Hello friend and Welcome!!

Before we dive right into the Audio Technica ATH M40x vs. M50x, grab a snack, sit back and relax because…

You’ve come to the right place!!

What I will bring you in this review

My goal for this article (and all articles really) is an attempt to outline everything you could possibly want to know about the stuff in question. In the case of today, it concerns the M40x and M50x, two highly regarded and extremely popular audiophile (or casual consumer) headphones, depending mostly on who you ask.

Today I will outline the M40x in great detail, and then compare it with the M50x. By the end, you should have a clear idea of which will accommodate your needs better!

With that, here’s the itinerary 🙂

Now without further ado, let’s get rolling!


For people who don’t want to read my in-depth discussion; I am sad, but I understand 🙂 Here are quickly the Similarities and Differences:

Similarities & Differences


Similarities

  • Both the M40x’s and M50x’s ear-cups rotate 90 degrees. The original M50’s rotated 180 degrees.
  • Both are closed back.
  • Both are Circumaural (Around-Ear).
  • Both have detachable cable features.

Differences

Price

The 50x’s are a bit more expensive.

Design/Build

The M40x has a different design.

It’s a bit more minimalist.

It’s smaller in stature and feels a bit cheaper.

I had a pair of M50s for 5 years and they took quite a bit of abuse. I have since sold the 40x, but it held up pretty well. Do keep in mind I never used it on a daily basis and it was mostly in brand new looking shape when I sold it.

An important note: The 40x’s have been known to snap around the hinge area because they don’t move/rotate as freely as the 50x.

Cushions

The 40x’s have softer cushions, making them more comfortable.

Bass/Sound.

The mid-bass on the 40x is more bloated, whereas with the 50x there’s a clear shelf but it feels and sounds more even from 20-200Hz.

The 40x by contrast is sloppily handled and doesn’t sound right.

The treble on the 40x is also metallic and artificial sounding vs. the more subdued nature of the 50x’s.

The mid-range is pretty similar, but overall I would say the 50x is a much better sound and easily stomps the 40x.

Cables

The M50x’s come with 3 cables: 1 coiled, and 2 straight of differing lengths (1.2m & 3m)

The M40xs only come with 2: 1 coiled, 1 straight. They are both also extremely long, which many people have complained about.

Impedance/Sensitivity, and Amp requirements.

The M50x has a bit of a higher impedance, meaning it requires more power to produce higher volumes, but it’s not enough to notice a difference to the casual listener.

The 50x also has a higher Sensitivity, meaning it takes less power to reach loudness levels (typically 100dB is the standard for loud).

Neither needs Amplification, but you could go with an affordable DAC if your PC/Laptop’s sound is poop.

Just don’t go overboard. An entry-level Amp/DAC like the E10K is perfectly fine, and I would not spend any more than around $75. It’s simply not worth it for a myriad of reasons that I won’t get into here.

Weight

The M50x’s are heavier, coming in at 285g as opposed to 240 for the 40x.

Indicators

The 50x’s have clear and classy indicators of the Right ear vs. left ear. They stand out considerably.

The 40x’s R & L indicators sit on the inside of the headband and aren’t as noticeable.

Color

The M40x only comes in black, while the 50x comes in different colors (Subject to change).

Read on for my official examination!

Introduction


Note: This article will show images of the original M50 but I have also demoed the 50x. I’ve simply never owned one.

I’ve since given away my M50s, owning them from January 2013 to April 2018, and I must say they are the most durable and time-tested cans that I’ve had the pleasure of listening to.

Of course, there are probably better models out there, with a flatter sound signature, less awkward frequency response curve, etc., etc. But who cares?

To my ears and thousands of others, they sound fantastic, all flaws aside.

Nowadays I will say that I do prefer a different sound signature than I did when I was first getting into the audiophile world.

I still enjoy the sound of a more bass-oriented type of can, I just don’t prefer it anymore if that makes sense.

In this evaluation, I will casually discuss the 40x and how it relates to the 50x. Should be fun!

How’s the build on the 40x?


Build Quality


Basking.

I really do enjoy it.

The build of the M40x is very solid, but it’s not quite on the level of an M50x.

Why do I say that?

Well for one very specific and important reason: The hinge. 

On the 50x, you’re able to rotate the ear cups completely 180 degrees. This allows the hinge to move freely with no restrictions.

What this freedom enables is a preventative measure from the headband snapping or cracking around that sensitive point where the ear cup meets said hinge.

On the 40x, this isn’t the case. They do not fully rotate like the 50x and therefore are prone to breaking in that very area.

The good news is that I haven’t had any issues with it personally, but your mileage may vary.

I do tend to take care of my headphones, but as mentioned in the open, I also didn’t use the 40x on a daily basis.

The hinge issue was the main concern from others about the build of the headphone in various online forums and review hubs.

Other than that, the 40x is built very well.

It’s smaller, more compact, and lighter than a 50x. It does feel a bit cheaper than a 50x but doesn’t feel cheap on its own if that makes sense.

The 50x feels more rugged and did survive 5 years of cold hard abuse from me.

When I first purchased it, it replaced my MDR-7506 for mixing and reference duties, but that’s a whole different story in and of itself.

All in all, both are very durable and you’ll feel like it was money well spent when you hold them in your hands.

I go into more regarding the build in my Video Review. More on that in a bit!

BUILD SCORE: A-

Back To Top

What about comfort?


Comfort


With a dash of green.

Comfort on the 40x is a bit of a mixed bag.

I wouldn’t call it bad or good; It lies somewhere in the middle.

For instance, the clamping force is a bit tight, similar to something like an HD600.

The cups do envelop your ears, but just barely.

I would say they’re roughly the size of the pads on the MDR-V6, but slightly larger.

Note: I do not consider a V6 to be a Circumaural headphone (Around the Ear), but rather a hybrid On-Ear/Around-Ear.

The 40x’s cups tend to dig into your ears a bit more than I would like and I do find myself making somewhat frequent adjustments.

That said, comfort overall is about average to pretty good.

It’s definitely not going to wow you, but from my perspective, it’s somewhat tolerable I suppose.

Compared to the 50x

Compared to the 50x, comfort is about the same although the 50x’s are a little more comfortable because their ear cups are slightly larger and do envelop your ears a bit better.

M40x COMFORT SCORE: B/B-

M50x COMFORT SCORE: B

COMFORT WINNER: M50x


How do they sound?

Back To Top


Sound


The sound of the 40x is definitely not neutral.

Bass

I would say the mid-bass here has a bit of a rise/bump in it, which can sound slightly unnatural to downright awful.

There’s a slight fuzz/bloat to tracks which can distract from not only the mids, but the overall clarity of the sound as a whole.

It feels like some type of thin cobweb or something.

Some will call this a bass-head can and others will claim it for reference.

I would most certainly never use these for reference and abhor the fact that they have been marketed as such over the years.

All in all, the bass response doesn’t look horrible from a graph, but it will likely start to annoy you after a while given that it’s simply trying too hard most of the time.

The mid-bass bump has been a longstanding issue in cheap consumer audio products, and unfortunately, the 40x suffers from the same problems.

Compared to the 50x

The bass on the 50x is going to provide more slam and impact, and I would definitely consider it more of a bass head headphone than the 40x.

The other thing I like about the 50x is that even though there’s a 5dB bass shelf across basically the entire low end, it’s handled much better and feels more balanced.

I don’t hear that bloat as I do with the 40x and I believe it to be a better overall portrayal of colored bass response.

Mid-range

Surprisingly, the mid-range on the 40x is very resolving and pretty accurate.

I don’t find it to be recessed (although it can be in certain areas) which is a welcome change from most closed backs with that V-shape type of sound.

Vocals and instruments have a nice clarity to them, with an overall sense of crisp excitement and detail.

V6 comparison

You will hear a clear difference between the mid-range of the V6 vs. the mids of a 40x.

I say that because I do a lot of mixing/critical listening, and going back and forth I was able to discern that the 40x sometimes has this weird way of pushing stuff back a little bit, while the V6’s mids are brought to the forefront, sounding more natural and nuanced.

Compared to the 50x

The mid-range on both of these is pretty similar, but the 40x emphasizes 1-2kHz a little more while the 50x opts for a rise around 4kHz.

Treble

The treble on the 40x to me is not good, at all.

It mostly sounds metallic and essy with an artificial type of portrayal that’s hard to ignore.

There’s a sense that this is indeed a $100 headphone as opposed to a $400 one.

To me, it’s palpable because of the fact that I’ve demoed over 120 headphones and kind of have a good idea about how different products sound in relation to one another.

For example, a particular high hat I used for a particular beat sounds great with a V6 but not so great with a 40x.

This is kind of disappointing and makes me want to either EQ it or scrap it in favor of something else.

This is what I mean by not considering the 40x first for mixing.

It simply doesn’t perform as well as a V6 and shouldn’t be your primary reference headphone by any stretch.

Compared to the 50x

The 50x’s treble was much improved over the essy nature of the original M50, and graphs show this as well. It’s much better handled than the 40x’s as well.

M40x SOUND SCORE: C

M50x SOUND SCORE: B+

What about Imaging?


Imaging


Utilitarian.

One thing that the 40x really excels at (that you may be surprised by) is Imaging.

These have a way of separating instruments and vocals very well, with a mostly natural-sounding character and some decent Timbre for the price. What is Timbre?

I definitely wouldn’t sit down and expect these to sound marvelous with Jazz, but they can work in some circumstances (good source files, etc.)

I think the Bass is too heavy for such an affair, but we’ll get into Genre in a bit.

The Soundstage is fairly narrow, but that’s to be expected.

Just don’t write them off completely though.

I do get an “out of my head” feeling at times which is completely awesome considering how isolating these are. I think Audio Technica did a fine job with this aspect of the headphone.

Compared to the 50x

I think Imaging on both is excellent and about the same.

I remember first hearing an M50 and being amazed at how good the Soundstage was.

A lot of purists might argue with me about that but I know what I heard.

I kept thinking stuff was going on around me and there was a very nice width to the image, despite it being a closed-back headphone.

I think this is one of the main reasons that the 50x is so popular and still remains relevant.

It does an incredible job of this and tends to win over the hearts of many who may not even be aware of what Soundstage is.

Update: A lot of this could have simply been due to the source file and how the track was recorded, and I’m fully aware of that.

Will you need an amp?


Amplification


The gang’s all here.

They are very pretty efficient at 98dB and have a very low 35 Ohm Impedance, and as mentioned earlier, I wouldn’t go any further than an E10K or K3 here.

Spend any more and you’re wasting money.

The M50x as mentioned earlier is 99dB. Not too big of a difference.

Here are some good options to consider:


The Budget Homie


FiiO E10K or K3.

FiiO K3 vs. E10K

Two peas in a pod.

Listening right now with the E10K actually, and it’s hard to believe this puppy is under $100.

For instance, the track “Over Sensitive” by Chelsea Jade, is so intimate that I feel as though the woman is speaking directly to me.

She sounds so close I could touch her face! Lol.

The E10K provides just enough power for an HD600/650, but you’ll have more than enough for the 40x.

With a gain switch and bass boost, you’ve got everything you need to enjoy music on a deeper level than simply plugging it into your phone.

The E10K is a fantastic value, especially considering how cheap and small it is

It comes with coaxial out, line out, and USB input for your PC/Laptop.

What types of music will these do well for?

Back To Top


Genre Pairing


Up close and personal.

Well, friend, you know what I’m about to recommend. Anything bass-oriented with these will shine given you understand the caveats of the 40x that we discussed earlier.

I listened to them with Indie Pop, EDM, Rap, and Hip-Hop.

They will also do well with Rock and Metal.

I would probably steer clear of Jazz, but Classical and Ambient-type stuff will sound very clear and detailed. I’m thinking of artists like 36, Claude Debussy, etc.

Compared to the 50x

The 50x and the 40x both do well with pretty much the same genres, so don’t become too concerned about this. Most anything you like will work with both (the big exception is Jazz).

So what’s the Final Grade?

Back To Top


Final Grade


I would probably give the 40x a solid C, and the 50x a B+/A- overall.

M40x FINAL GRADE: C-/D+

M50x FINAL GRADE: B+/A-

WINNER: M50x

What’s the Final Word?

Back To Top


Final Word


The 50x has been trashed quite a bit over the years without merit.

Back when I first owned the M50 around 2013, I fell in love.

It had its issues, but fortunately, the M50x improved upon the glaring treble flaw and made an already great headphone even better.

Don’t believe everything you hear from the snobby audiophile internet parrots.

The 50x is a solid choice for bass heads and I still think it’s a highly relevant product today.

It’s durable, sounds excellent, and also comes in a Bluetooth version nowadays which I plan to invest in at some point for the gym.

Take this recent testimonial from Patron and friend Stefan as an example of someone who’s happy with what he has and enjoys the sound immensely:

Thanks so much for your insight! And so glad to hear that my first impression wasn’t crazy or totally off. “It just sounds sublime” describes exactly my listening experience. Tbh I almost cried yesterday, when I was listening with the 50x to some very familiar songs. I read somewhere that this headphone can be a bit harsh in some highs and with one song I’ve heard that too, but didn’t seem like something that can’t be eq’ed. Finally I seem to have a headphone that works for listening to music and also practicing piano. I’m really happy with these ones.Stefan Rutkowski

Hey Stu,

Wonderful review.

Despite so many differences I still can’t decide which one is better.
M40X is lighter and quality of cushion makes your head not getting tired too fast – you can wear them for quite a time.
It appears that M40X is even a bit better choice of product – it’s more comfortable, tighter sound stage(if timing is good, then it’s okay).
But M50X has also it’s own pros – better ear-cup mechanism, if M40X snaps then it’s over. And sound quality doesn’t stand behind M40X either.

And if there is a problem with cables in both cases, you can purchase spare ones, since those are detachable.

Which one would you really choose without looking at the price Stu?

Reply
Stu August 12, 2016 - 12:52 am

Hey man!

They are each headphones that serve different purposes. So if I was just looking for something casual I would go with the M50x, but if I needed something great for mixing I would go with the M40x (if I had to choose between the 2). My top recommendation for mixing in this general price range would be the MDR V6’s.

Thanks for stopping by brother..

Blessings,

Hi Stu,
I’m wondering about the audio quality, bass and vocal, (i’m enjoying every type of music and also movies) which one do you recommend?
Thanks

Reply
Stu December 2, 2016 - 3:48 am

Vincensia,

I have both and I do prefer the 40x’s over the 50’s and 50x’s. The sound of the 40x’s is a bit more balanced overall, with more detail retrieval and less bass, but it still slams nicely. The 50x’s are probably more durable, but it’s close. The 40x’s don’t seem to move or rotate in quite as many ways, which may contribute to the build issues around the hinge.

Hope that helps! Let me know..

Blessings,

Hey!

Are you looking for a fun and lively sound, or a natural and more subdued sound?
Closed back or open back?
Price range?

Off the top of my head, the Sennheiser HD 598 is great for watching movies and casually listening to music. Does well with pretty much any genre. But let me know some more information and perhaps I could give an even better recommendation.

Nice review Stu,

If you were a guitarist who likes to play along to music and backing tracks and also records his own music with Guitar, drums, bass, keys. Which would you recommend? I had the Sennheiser hd555’s for years but when I bought the Sony mdr7506’s I couldn’t believe how much I was compensating for. The Sony’s are very natural but the Sennheisers are extremely comfortable. The Sony’s do win this battle on mixing but they seem to lack something for me. Would the M40x be that something? Or could you recommend something else?

Jamie.

Reply
Stu February 15, 2017 - 3:53 am

Hey Jamie!

I’d probably go with the Sony MDR V6, which is similar to the 7506 but less bass. Check out: Sony MDR V6 vs. MDR 7506.

A lot of people say the 40x’s are neutral but they do have a bit of added bass emphasis. You could do better for tracking, reference, etc. The V6 is very neutral.

Hey! I would like to know which ones better for This kind of music: Hotline miami Sountrack for example. Song: Run-iamthekidyouknowwhatimean, Or Crystals-MOON. (M40x with Brainwavz pads)

Reply
Stu June 21, 2017 - 2:50 am

Hey there!

Not sure as I don’t own the Brainwavz pads. I have the regular stock pads for the M40x. Basically the difference in these two headphones is the 40x is more balanced across the board, but still has a nice bass emphasis, while the M50x is definitely more bass heavy. The difference is subtle though.

Let me know if that helps!

Hey there Stu!

Thank you for your review. My M40x joint is broken and sadly the internal cable has snapped too. It sounded really great for me and I got used to it but I don’t want to buy another M40x. I’m planning to buy another headphone, and I was thinking about the M50x but I’m still not sure if it’s the best replacement. Do you have any recommendations for an upgrade? I will be using them mainly for audio production and mixing; mostly EDM and trailer music. Thank you.

Reply
Stu June 26, 2017 - 2:59 am

Hey Yazid!

I would definitely go for the Sony MDR V6. It’s the perfect studio headphone and it’s great for mixing/mastering! I have a pair and absolutely love them. Check out my Sony MDR V6 Review for more info and let me know what you think and if you have any other questions.

Hi Stu! Thank for the review!

My M40x joint is broken…. I really love the sound of those headphones. I was using them to listen to all types of music and watch movies in several different languages. The clarity of the M40x is outstanding and helps me keep up with the vocals under the dialogue. Which one of these headphones most resembles the balance, tight bass, and detail of the 40x? Is it the M50x or the MSR7?

Thank You

Hi!

Thank you very much for this review. I’m listening to music (with an iPod) for a minimum of 4 or 5 hours a day, often walking in the city. I listen to pop, rock and metal. I’m looking for closed headphones with a natural and detailed sound. Which one would you recommend, the MDR7506 or M40x. My budget is around that price range. Thanks again!

Hey Baris!

Between those two for portability I would probably go with the M40x. I myself prefer a straight cable when walking, but just know that the cable is a tad long for on the go purposes. I love the sound of the M40x, but I may recommend the Sennheiser HD25 for an extremely portable headphone. It’s awesome! It’s a tad above your price range, but it’s lightweight, indestructible, has a short cable which is ideal for being out and about, and sports a crispy, exciting, and detailed sound.

I also love the M40x, but you may not like the long chord for portable use. That’s all.

Let me know what you decide and if you have any other questions!

Hi Stu! Great article 🙂
I’m a bass player look to start into music production so my needs are three fold:
1. Mixing/Monitoring.
2. Maybe using to make bass tones/live on stage as in-ear monitor.
3. General purpose listening.
Priority of work is in same order.
I am caught between the M40x, M50x, and Sennheiser HD380pro and HD598pro. Which one is the best? I want something I wouldn’t have to replace over the next 4-5 years as I’m mostly buying headphones as a monitor.

Stu August 8, 2017 - 7:18 pm

Hey there!

The M50x is more for general purpose, while the M40x is good for mixing/monitoring, but also works as an all purpose headphone. The HD380 is more of a bass heads headphone like the 50x, but also has a bit of a recessed mid-range as well. The HD598 is a very flat headphone that’s more suited for airy music like jazz, classical, and lighter stuff generally. Its bass is very light and lean as well, so be forewarned.

Now, as for what I think you should go with?

It’s hard to say. The M40x does have the issue of cracking around the ear-cup/headband mechanism, and its pads tend to crack and peel over time. I haven’t had any issues with mine due to the fact that I have a lot of headphones so I have the luxury of not putting so much wear and tear on them.

The 380 is a V-shaped headphone, so it’s better for general purpose listening. It’s a bit harsh/grainy at times though.
The M40x is the most all around, and works as a mixing/monitoring can as well.
The 598 is great for mixing/monitoring, but not so much general purpose, unless all you listen to is lighter stuff.
The M50x is another bass heads headphone, not as good for mixing/monitoring, but good for general purpose.

With all that said, my recommendation is the Sony MDR V6. You will have problems with the ear-cups (like the 40x), but it’s a lot more durable and suited for the long haul. The 40x is still really good, and it’s a close call.

Let me know what you think!

They’re about the same to be honest. Are you looking for something to mix on or something to listen causally? 40x would be better for mixing, 50x is better for fun listening. 🙂

Hi Stu !
I’m focusing on hearing music , playing games , that’s all no mixing and magic stuff , what do you recommended ? I’m more of a bass guy I think but more prefer the detail of the music

Reply
Stuart Charles Black November 27, 2017 - 3:08 pm

Hey man!

I have the M40x’s and I’ve been listening with them intently the last week or so. I think they sound pretty fantastic for the price point, and provide plenty of detail that you’re looking for. The bass hits the sweet spot for the most part, and there’s enough of a boost in the upper mid-range to provide very good imaging and instrument separation for a headphone in this range. The 50x’s are good, but the bass may be too much. For you the 40x’s seem like the perfect fit.

The treble on the 40x’s is very controlled for the most part, but you will notice a bit of a metallic, “essy” flare from time to time. This just simply means they can sound artificial, but it’s so minuscule that you likely won’t notice. The mid-bass can sound a tad bloated as well, but again, it’s a relatively minor complaint. The bass thumps nicely with most tracks, and provides plenty of slam without getting out of line.

For gaming, neither the 40 or 50x’s are top shelf, but it’s hard for a closed back headphone to excel in the bass and soundstage department simultaneously. If you were looking for strictly a gaming headphone, I might recommend something like the Samson SR850, AKG K240, or Audio Technica ATH AD900x. But the catch is that none of those headphones have a lot of bass.

I fully recommend the M40x’s at their price, and find them to be almost a steal considering the sound quality you’re getting.

Thanks for stopping by and keep me posted!

Blessings,

Hi Stu!

Need some advice please. I’m currently looking for a headphone for home use. Mainly for music, movies, some gaming. I have a sennheiser momentum 2 wireless already and I wish to get something that is different from the momentum. I really like the momentum sound, but I want to try out something different. Previously I have used mostly In-Ear models. I am considering the AKG K240, K72, M40x/50x, Grado Sr80e, and Skullcandy Crusher Wireless. Which 1 should I get or do you have another recommendation. Thanks in advance!! Really good review btw!

Calv December 10, 2017 - 9:31 am

Hey Stu,

In the end I ordered the AKG M220 Pro from Massdrop, a similar headphone to the K240 studio. I read a lot of reviews that the pads on the m40x and 50x wore off after awhile and I read your list of recommended audiophile headphones and saw that the m50x and momentum 2 both fall under the closed back, casual listening category. I wanted something different from the momentum. I listen to all kinds of music except for metal and country. I’m just wondering if i should get the FiiO BTR1 for the M220 Pro as it has a impendance of 55ohm. Unsure of Fiio A1, A3 or BTR1.

To add on: The headphones I have are the Momemtum 2 over ear wireless, AKG m220 pro (coming soon). For in ear: AKG n20u in ear, Nuforce edc from Massdrop, Jabra Rox and Soul x-shock. Maybe you can advise which amp gonna benefit me more.

Also I should mention that I’m mainly using a Samsung S7 Edge and a Samsung Tab S3 for music and movies through Spotify and Netflix. The reason I’m thinking of getting an Amp is because the S7 edge is really quiet and lacking power as compared to my previous iPhone.

Your site has been most useful! Thanks! Thanks for your time!

Stuart Charles Black December 11, 2017 - 10:26 pm

So I assume you will primarily be listening to the M220’s in a quiet home environment? You’re not going to be very happy with an open headphone out in public.

E10K seems a great option but i will be using the M220 with my s7 edge and tablet only. E10k seems more for PC/laptop usage due to its USB connection. I like portability so i ordered the BTR1 instead. Btr1 seems useful for my other IEMs too while on the go. Thanks for the recommendation!

Hey stu!
My BTR1 has arrived and been using them for the past 2 days. Its awesome! Added alot of punch to the bass and better instrument separation. Most importantly it amplifies the sound by a lot. I have tried with 3 iems so far – nuforce edc, soul sl49 and akg k375. They kinda sound like my sis b&o h5 now esp the akg k375. Lol. You should give it a try if you have the chance!

Thanks

Reply
Stuart Charles Black December 31, 2017 - 3:58 am

Hey J!

Hmm that’s tough. The 40x is phenomenal, but it’s more suited for mixing/mastering. The bass on it is somewhat lighter, with a more balanced response. The 50x has a deeper bass with more impact, but it’s overall sound signature is more V-shaped with a lot of peaks and valleys. The 50x may be better for you as far as bass, but I may recommend the 40x due to it’s clarity and detail. The only issue I have with the 40x is the mid-bass hump between 100 and 200Hz. It’s a bit bloated, but overall it’s not a deal breaker. Hope that helps!

Let me know what you decide.

Hey Stu,

Great reviews, nice detail! Quick question. My Denon AH-D1001’s are dying (one speak just went dead), so I am in the market for some headphones in the 100-150 range. Your review on the Audio Technica caught my eye. That said, I love the bass on these and I am looking for the same or better bass (mainly for house, ambmient, disco-tek, etc.). Do you recommend the 40x or 50x, another model or brand/model altogether?

Thank you for your time.

Wouldn’t bother with those. Got a chance to try them out and they’re pretty bad. The V Moda M100’s are very good however, but they are strictly for bass heads.

Sorry for all of the questions. Going with the M40X, I am going to be wearing these 8-9 hours a day, working at my desk….should I consider getting different earpads (ones that do not change the sound for the worse)?

Stuart Charles Black February 26, 2018 - 10:44 pm

I would say yeah on that. The 40x’s will get a tad uncomfortable over long periods. If comfort is a primary concern, you may opt for the Status Audio CB-1. It does have a better Soundstage and is more comfortable overall. Still, search out a good set of pads for the 40x first before going with the CB 1’s. Here is my review: Status Audio CB 1 Review.

One follow-up question. Would you say the M40X are the best over-ear headphones for house/heavy bass, between $100-$150?

Dood! Just received my m40X with the angled pads…..SWEEET! Excellent, crisp bass with VERY clear/deep sound. Before I switched the pads, I used the stock ones first, so I could compare. I am not an audiophile or anything close. I barely knew what to look for when shopping for new headphones. That said, I did notice much (if at all) or a sound change between the stock pads and angled pads. With the stock pads, I felt there was a tad more isolation/seal. I could actually feel a little more pressure on my eardrums because of it. The angled pads seal well too, just not to the point where I felt the pressure. I could have worded this review better, but, at the end of the week…this is what I have. 🙂 Thank you very much for your guidance Stu, I greatly appreciate it.

Hey, I’m about to buy one of them and I’m not sure which one will be the best for my use.
I’m not a DJ or something like that, just a heavy consumer of music (mostly at home).
Usually, I listen to Alternative/Progressive/Indie Rock, and Sometimes for some Metal and Electronic.
If to be more specific, mostly I listen for: Radiohead, Pink Floyd, Muse, Nirvana, Arctic Monkeys, Dream Theater, Porcupine Tree, Grandaddy, System of a Down, Bjork, Atoms For Peace, etc.
I really love to ear a clear and detailed sound.
Which one would you recommend me to buy?

Would you recommend the 40 or 50 for me? I plan to use them mostly for the gym while weight lifting and some occasional cardio? I read one of your earlier posts about part of the 40 peeling off and it starting to fall apart? That’s exactly what I don’t want as using headphones for the gym is going to get them constantly wet with sweat and put a load on them I want and need them to be durable to the point that they can withstand that wear and tear. If you could point me in the right direction it would be greatly appreciated? Also whichever headphones u recommend.

Reply
Stuart Charles Black August 1, 2018 - 4:22 pm

Hey man! The 50x’s are a bit bulkier so if portability is a concern, go with the 40x. If you would rather have more bass emphasis, go with the 50x. It’s really a trade off and what you prefer more. The 40x is a bit more balanced across the spectrum, while the 50x is more of a bass heads headphone. Outside of the cup issue, both are very durable although the 40x has been known to break around the hinge (hasn’t been a problem for me but your mileage may vary, especially if they’re going to be in a different environment).

My 50’s started peeling and cracking after about a year or two, but if you’re in the gym with them on everyday it may happen faster.

I hit the gym 4 days a week and use the Uproar Wireless. They may or may not appeal to you, but they’re extremely durable, pretty comfortable, and have a good sound while being ridiculously convenient. Battery life is fantastic as well, and I even wear them at the pool. The cups have gotten wet more times than I can count and they are still going strong. The longevity factor is extremely impressive with these. Now I realize you may want something more fashionable which is fine. They are also a bit outdated but I’m on my second pair (first was stolen) and I couldn’t imagine going to the gym without them. If you’re into what’s NOW, I completely understand.

In that case, I would just go with a Beats Solo 3 to be honest. They’re wireless and the cups are actually made of a better material than the 40 or 50x. Sound is similar to a 50x, so you’re still getting a very fun sound signature without the hassle of a chord and the cup issues. Plus they fold nicely and are very compact.

The good thing about the 40/50x is that you can replace the ear cups but you may not want to do that.

Hope this helps. Let me know!

Stuart Charles Black August 11, 2018 - 1:53 am

I’m really not too sure about that but I would think not as the 40x is a smaller headphone than the 50x. What exactly do the skins cover?

Reply
Claude August 23, 2018 - 9:36 pm

My 2 cents: I have both and love both. This is what I’d say soundwise: M40x for playing instrument, M50x for listening pleasure. The difference in sound is tiny but those small details (slightly boosted bass and treble) make huge difference in how much more impact music has while listened on 50x. 40x are bit too clinical. On the other hand: for long listening sessions 50x are more tiring due to emphasized highs. 40x give you real sound – exactly what you want when playing.
Comfort: 50x win hands down due to slightly larger cups, in 40x my earlobes hurt after a while (and my ears are pretty small).
I play guitar and a little piano and for playing always use 40x. For listening 50x (or hd650).

Reply
Stuart Charles Black August 25, 2018 - 1:16 pm

Hey Claude!

Love your comment but I definitely don’t think the 40x is clinical. I mean it’s a fairly accurate portrayal with some metallic sound in the treble which can be problematic at times. Also the mid-bass is a bit over-exaggerated but overall it’s just a crisp thumping sound and a whole lot of fun. The 50x like you said is def taking steroids while the 40x is a mostly natural body builder who takes like creatine or something. I guess that would be my analogy. Agree that the 40x is mostly a real sound but it’s still colored to a degree. You’re right about comfort as well the 40x is just smaller in all areas including it’s cups. I can deal with it but some people won’t be able to. Thanks so much for your input and let me know if I can help out with anything in the future!!

Hey stu! Thanks for the amazing review. I decided to buy M40X’s for general desktop use after reading it. Though while I wait for them, I was as wondering how prone they are to breaking? This is a pretty big factor to me.
If they do happen to break at the hinge, is it possible to repair them with some parts bought online? If not, would super glue/duct tape do the trick or would it make them too uncomfortable?
Thanks!

I would say from my experience not very prone to breaking. Remember though that I don’t use them on a daily basis but I would say with great care taken you should be fine. As far as repairing them, not too sure on that but hot glue has worked for me in the past with other stuff 🙂

So…wow… update time!
I just put them on 10 minutes ago and started playing some EDM music. I’m blown away. Keep in mind though that the best headphones I’ve had before these were the really crappy Sennheister 201s, which I used for a few years.

Here’s my first impressions:
1. I really enjoy the strong but surprisingly comfortable head clamp (compared to my previous phones which would kinda just hang on your head instead of actually sticking to it). The pads are spongy and soft, and my ears fit really well, too.

2. Sound quality really is amazing, especially for the price – I even got a 25% discount on them, so lucky me!

3. Noise isolation is so good that I can’t even hear my very clicky mechanical keyboard as I’m typing this, which is kinda messing with my brain, hah. It also works just as well the other way – I was playing some Eminem on max volume, and if I just smooshed the 2 pads together, you could barely hear it.

4. The cable is very nice and thick, and lighter than you’d expect for a cable like that. And it’s detachable so I can replace it for cheap if it does miraculously break (plus, you get a free first replacement with the other cable that comes with them).

5. Design wise, they look really awesome, much nicer than on the internet. Online pics don’t really do them much good! I was worried about the hinge, but it’s actually sturdy as hell. I don’t expect them breaking any time soon, at least without accidentally sitting on them a couple times, haha. The headband is soft, and actually pretty flexible, which lets you stretch it like this: https://imgur.com/QnKk5dX without much effort.

Overall, I’m impressed, and also thankful for finding this site and this review just in time before I pulled the trigger on the headphones. Couldn’t be happier right now.

Thanks for everything, Stu!
Peace out.

Stuart Charles Black September 12, 2018 - 5:30 pm

Hey man!

So glad you’re liking (loving) them!

1. Clamp is real good for me as well. They hug fairly tight but it feels good.
2. Awesome! Yeah you got them for a steal wow. Love the sound especially for a headphone in this price range. Price to performance ratio is phenomenal.
3. Isolation is indeed very good. Great for on the go where you may be in the company of people who don’t want to hear you blasting Tears for Fears. Lol.
4.Love the cable. It doesn’t feel cheap at all which is what I was really impressed by. In your hand it feels like quality. Plus you get 2, a coiled and straight version. Incredible value.
5. Love the minimalist design of these actually. Yeah if you take care of them the hinge shouldn’t be an issue. The only thing is that the cups don’t rotate quite as much as the original M50 or 50x. Notice how they “stop”?

Hi Stu!
Duuude, at first I just wanna thank you for sharing your thoughts and experience in this blog. Wonderful job – Keep it up!

I already have the ATH-M40x’s (which I love) and I’ve just ordered the HD600. When M40x is my multipurpose all rounder and HD600 will be using mostly for mixing/mastering, I’m considering something between for studio usage, that will give me a different perspective and some additional informations – even if it was V-shape.

I’m focused on the DT 770 (Pro or not) 250 Ohm, which I’ve tried, because:
– it has relatively wide soundstage
– sound is more like distant/open but also pretty clear and detailed
– the instruments separation is outstanding
– bass is tight AF
– neither cold nor warm sounding

Also thinking about cans I haven’t tried yet:
– DT880 250 Ohm (but I’m afraid it could be just colder HD600 with less bass and not as “different” as DT770’s)
– DT990 250 Ohm (even more unnatural and V-shaped than DT770’s)
– AKG 702
– AKG K712
– AKG K550

What headphones can you recommend me for my purpose I’ve mentioned above and why?

Cheers!
Mark

Stuart Charles Black September 15, 2018 - 7:21 pm

Hey man!

Thanks for the love! What kind of “perspective” are you looking for?

What is your price range as well? I have a few ideas in mind but they are semi expensive cans.

The headphone I’m thinking of that’s kind of in this price range that you’ve mentioned is in fact a HIFIMAN Sundara. It straddles a nice middle ground between cool and warm, but still very detailed, excellent bass response, and a somewhat darker sounding treble with a fantastic mid-range.

You’re right about the 880. Very cold, even colder than an HD600. DT990 is very peaky in the treble but I still like it’s open characteristics. K702 has an immense Soundstage that you may enjoy for something like Gaming. The K712 is the best out of that line. Also perfect for Gaming and it’s immensely detailed as well.

Are you looking for a can that matches those characteristics that you mentioned about the DT770?

If so, I do think The Sundara fits that criterion pretty well. I also really like the MrSpeakers Aeon Flow Closed as well as something like an Audeze LCD-X.

I think something like a K712 will also fit your description as well.

Check out my Sundara Review and let me know what you think!

I would narrow it down to the K712 and the Sundara for open backs. The Sundara will have more bass while the K712 is a bit more rolled off. Both fantastic sound signatures. With the Sundara you’re getting a bit more mid-range presence vs. the more relaxed K712. The K712 has a bump at around 2k while the Sundara rises a bit around 1k. Both immensely detailed and open sounding. Treble on both tends to be on the darker side which I have come to really enjoy out of my headphone experience. You can listen for much longer with little to no fatigue, and everything just sounds so much more natural and true to life.

As for closed back, I love the MrSpeakers Aeon Flow paired with a Chord Mojo. The sound is absolutely mind blowing, and similar to an open LCD-X. You will notice a peak in the treble which renders them a bit sizzly at times but it’s a minor nitpick. Here is my review.

Keep me posted on the decision making process!

I’m currently saving money for getting my first studio headphones, and I’m always reading your website because it’s a pretty useful guide.
I’ve been investigating a lot and now I’m in the last round of the battle, I’m in between the Audio Technica M40X and the AKG’s K712… yes, they’re surely not equal; different form, different prices…
But I need your help for choosing a Winnah!
Could you please lend me a hand bro?
The genres that I’m intending to produce are EDM, Christian Pop-Rock, and Rap Bass.
I’ve always wanted Open-Back headphones for not being myself entirely isolated from external noises, because sometimes you have to help at home by taking tuna cans from a top spot :P!..
But then I realised that maybe at some point I’m gonna need to record something, and Open headphones leak a lotta sound; when remembering K712’s +amp price, I really prefer the M40X’s (as a ‘closer’ option in price terms).

Right now I’m 10 bucks away to get the M40X’s, I want to keep learning about mixing, but I can wait enough time for saving more money and invest in the K712’s and an amp like Fiio E10K, and learn other things until the moment comes (here with ma Microsoft Lifechat LX-3000 headphones lol).

So, I’m asking for advice:
¿Would be the K712 superior in details than the M40X?
¿What do you think?
¿Which one will translate better with the JBL LSR 305?

Thank you Stu, you da best.

Eduardo.

Hey Eduardo!

Hmm. This is kind of a toughie. First I’ll answer your questions.

Detail wise, yes. The K712 will definitely provide more, as the mid-range is much more balanced overall. You’ll notice an increase in vocal and instrument transparency and intimacy most notably vs. the more recessed mids of the M40x. The 40x is no slouch though. For $100 it’s immensely detailed.

According to this question, I think you should probably save for the K712. To be honest, I personally wouldn’t use the M40x as my primary mixing can nowadays. There was a time when all I had was an M50 and it did well, but you’ll want something more honest like an MDR V6 for a budget option. More on that in a second.

As far as translating to the 305, for sure the K712 will work better. You ideally want a semi-flat bass response, and perhaps a bit rolled off but not too rolled off. If there’s no bass you’ll end up overcompensating on the mix. The 40x’s bass can be a tad problematic in the mid area around 200Hz. There’s a bump there which can sometimes sound a bit unnatural and fuzzy/kind of forced. It’s a minor thing but for mixing we need the best accuracy possible. For general listening it’s great because it adds some intensity and power behind the low end.

Something more inline with the reference quality sound of the K712 would be a V6 for certain. I recommend this first to most everyone that needs a flat reference monitor in the budget category, as it’s an excellent performer and a quintessential classic that’s been around for decades.

Here’s my review: Sony MDR V6 Review!

The V6 will also translate very well with the JBL’s as both have a fairly balanced response. I really like the FiiO E10K and it would make a perfect match with the V6 as well. For the K712, the E10K should be fine. I’ve been using one to power my HD600’s which have a Sensitivity of 97dB, right on the cusp of being considered “low”. Anything below 97 generally needs quite a bit of current to reach acceptable listening levels. The K712’s by contrast is 105dB so you should be fine with an E10K pairing should you save for the 712. I do tend to use the gain switch on the E10K more often than not with an HD600/650, but it’s not like mandatory. Overall it’s a fantastic unit and for under $100 an incredibly easy purchase.

Here’s my E10K Review for reference: FiiO E10K USB DAC Review!

I know you were set on the 40x but my personal advice is to get the V6 if you don’t want to wait on the 712.

I really hope all that helped. Please let me know and keep me posted on your decision making process!

Best Regards,
-Stu

Right now I have the Cowin E7 Pro headphones. They worked well initially, but they have gotten worse over time. I walked around campus with them on, but I think my goose steps have really worn down the sound volume. I crank the volume up to 100% and I cannot even hear my audio book. It is a shame. I shelled out almost $100 for them and now they are not as good as when I got them. It has been a disappointment.

I do have a question. With the ATH-M50x, will they hold up to walking around campus? I go to UC Santa Cruz and there can be some heavy hills and steep valleys, so I do a lot of walking. I probably do about 5 miles a day when I am on campus four times a week.

Thank you so much for all your help and I hope you make it a great day!

Yeah the M50x will definitely hold up Alex! In fact, both have good clamp pressure on your head and don’t move around at all. I use my M40x’s for mixing sessions from time to time, and the M50 way back when I had the original model. Both great headphones but a little different sound signatures.

You’re obviously leaning toward the 50x which would be a great investment. I think you’ll love the sound signature of them if you’re more of a casual listener. 

Side note: I think it’s really cool you go to UC Santa Cruz. If you’ve ever seen Pulp Fiction, Vincent wears the Banana Slug shirt after the scene where they accidentally kill Marvin, lol. I actually bought that same shirt and I wear it all the time! Pretty funny considering I never went to college there. XD

Anywho, keep me posted on your decision!

Dear Stuart,

This is a very thorough and comprehensive review post.

I loved how easy the review makes it for readers and no additional research needed. You left no stone un-turned in explaining how it all works. The comparison chart and the video you embedded is very helpful.

For sure looking for a headphone and Audio Technica ATH M50x is what I am planning to buy after reading you post.

Wishing you all the best!

Paul

I actually like that the cables are long as it gives you more leeway for movement, so not quite sure why people have complained there.

Seriously, these two products are very similar, and have quite a large price difference. I think I would go for the M40x if I had to pick one, however I would prefer something with a bigger piece to cover the whole ear, as in this way you won’t get too much outside noise coming through.

Thanks for all the trouble you have gone to to compare the two head phones. It is great that someone is prepared to do this for all the consumers out there so that they can make informed discisions.

Great comment Michel!

For me, longer cables tend to get in the way more often than not. I can’t tell you how many times I’ve run over my HD600 cable with my chair. Lol. Still comes out on top though!

Thankfully, the 40x comes with a coiled version which is awesome for the studio. I do prefer straight cables on the go though so I agree with you that they can be better in certain instances.

You’re right about the 40x; the ear-cup is a tad large for even an average sized ear and does become a tad “hot” at times when they’re on your head. I suppose that’s a small trade-off with more budget options and headphones around the $100 range. There will always be something you’re not completely on board with but overall it’s a fantastic headphone and worth the investment.

Thanks for stopping by! Don’t hesitate to reach out if you ever need a hand!

Hi Stu – really love your in-depth reviews! – I have a small home studio – ie a bedroom! 🙂 – and both record music and play music through a pair of KRK monitors. At least I like do. Due to ‘other people’ it’s not always possible. I have a pair of AKG K702 Reference headphones which I use when I can’t play through the monitors. I think they’re excellent and, being open-backed, I can hear if someone is shouting for me. Although I often say I can’t hear because I’m wearing headphones. Sh… 🙂

Anyway, I’ve been wondering whether or not to buy some ‘listening’ headphone just for listening to music rather than recording and mixing it. It’s an absolute minefield out there but ultimately it comes down to your ears and your own personal preferences. Although the sound of the AKGs is great, the cups aren’t the most comfortable, for me, for prolonged use.

So, these Ms are in the right price range and I’m thinking the 40s would be the better bet. Would you agree? Or is there something else about the two I should consider? Or even another set of cans altogether? Argh! 🙂

Also, one thing I wonder and worry about – I’m now used to the sound of the K702s so would mixing up my listening between the K702s and audiophile cans affect my perception when I’m recording and mixing with the 702s? I wouldn’t like to lose my audio perception. What do you think?

Awesome Ian!

Lots to discuss here – I think you make a great point about perception. Our ears do tend to get used to a sound but I’ve found from experience that they will quickly adapt. Your reaction to a new headphone may be something along the lines of “Wow. This is Bollocks.” But don’t panic just yet as the more your brain gets accustomed to the sound the more satisfied you’ll likely be (that is if the headphone is any good).

Fortunately for you the 40x is a great casual headphone that you’ll enjoy in most circumstances. It does have quite a bit more bass (especially mid-bass) than the K702 but I think you’ll find it a welcome change from the 702 even though that headphone is incredible in it’s own right.

Were you specifically wanting a closed back? You may really enjoy the Sennheiser HD650 for easy listening. It’s probably the best all around headphone I’ve heard and an easy recommendation for 99% of people.

Let me know!

Hey Stu:
Thanks for sharing this website. I love listening to music inside headphones. I wonder if they work inside smartphones.

I would definitely have to vote for the 50’s for one big reason…I just can’t stop snapping my stupid headphones.  Do you have any idea how horrible it is to try to tape them together and actually use them, but I’ve had to do that TWICE!  I am a spazz I guess, but I’m definitely willing to spend the $40 more for a better quality if it means they are less likely to snap!  Great review – you are so thorough.

Hello,

Have you had an opportunity to listen to the 50x Bluetooth version that came out not too long ago. If you have, please share your thoughts. Thank you!

Stuart Charles Black January 14, 2019 - 7:19 pm

I have not but I really want to get my hands on a pair. In fact, I’m looking to sell off most of my headphones and just purchase that one for the gym and keep a couple others for studio (Probably will keep V6, HD600 and 9500) but I’m still undecided. I will keep you posted!

Hi Stu, do you still have this cans? I’ll post my quick review after listening to them and comparing with graphs from rtings, they are pretty accurate. (i do not own any, but planning to get one, just still can’t decide which) 🙂

m40x:
– Low bass is suffering because mid bass and high bass is overemphasized (from around 60hz to 250hz), mid bass ~5db and high bass ~6db in average.
– Mid range is ok with small accent in 1-2khz range, around 3db peak.
– Treble is so artificial with 9db pick at both 10 and 15khz, looks like a huge ‘”W” 🙂

m50x:
– Bass range is way better than on m40’s, it’s more accurate with average ~1db peak in mid bass and ~3db in high bass, also has better extension in low bass probably due to slightly bigger driver.
– Mids are almost perfect, the range is flatter and neutral than m40x.
– Low treble is perfect while mid has around -9db at 6khz, and high treble almost doesn’t exist lol, i mean there is a peak at 10khz (~4db) and after that nothing, roll off till 17khz, and that’s why m50x sound lifeless and harsh, high treble is way underemphasized…

Tbh, both m40x and m50x sounded bad to me m40x because lack of sub bass and artificial highs and m50x high and mid treble are underemphasized, they need EQ or some mods for a “fix”. i just wonder which one is better for EQ, m50x looks more durable, and have better extension, but how it will perform if you put some big gain in those dips, did you play with EQ on them, or is there any better choice in this price range today? Have a nice day!

Yeah 40x is horrible lol. Your impressions are right in line with mine. Metallic highs, boomy mid-bass, terrible mid-range, artificial sound. So glad someone else is pointing this out. It’s been ages since I heard an M50/M50x. I used to own the M50 and the highs were super harsh but I still think the sound is way better than the 40x and I still recommend the 50x in certain instances. They fixed the treble on the M50x (which I’ve also heard via a friend some years back) but I’ve never owned it. My plan is to get an M50xBT for the gym (and as a way to revisit the sound) because all these BT earbuds and headphones companies have been sending me are pretty bad haha.

You should leave a comment on my official review about how trash they are LOL. I don’t know if it’s just me but it seems like people are still saying these are good when they are actually objectively dog shit. xD

Hi Stu,
I was thinking of getting the M50x and came across your review (which was very useful btw). But now I have found out about the M50xBT and on their website they claim it to have the same clarity as the M50x. Are these two the exact same in terms of quality but with the plus of the BT? Which one do you recommend for a balanced use of mixing and sound design but also personal use (music, movies, etc)?

Reply
Stuart Charles Black June 5, 2023 - 2:27 pm

Hey Santiago!

Aw, man! I’ve been wanting to buy the M50xBT for quite some time, but I don’t know for sure since I haven’t actually put the BT on my fat head. I want to say yeah but don’t quote me on it. That said, from the graphs they look pretty similar. There’s still a dip in the low mids around 400Hz, and there’s also still a bass shelf from 20 – 200Hz. The upper mids and treble look very similar. I’d say if there is a difference, it isn’t enough of one to worry about. I think you should go for it!

Let me know what you decide. 🙂
