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 to your needs better!

With that, here’s the itinerary 🙂

Why Should You Trust Me?


Because I know what I’m talking about. I haz an education!

Lol. I’m being funny but I’m also serious.

I don’t have fancy credentials like some people (and I don’t think that automatically means you’re legit by the way), but like Craig Boyles said about me on his website Mage Audio,

“Stu knows headphones. He’s reviewed over 70 of them on his website.”

I’ve been a headphone enthusiast for as long as I can remember, ever since I had a pair (or 8) of Sony MDR V150’s. I’ve loved music and everything about it for equally as long. I’ve been making and producing music for over 10 years, and have learned a lot about EQ and sound a long the way. I’ve sold beats, I’ve given them away, I’ve collaborated with a lot of people, and I’ve had a lot of fun.

I’ve had plenty of experience with high end amps, entry level ones, and anything in between. I don’t claim to know everything, but do I know what sounds good and what doesn’t. I know what’s worth your money and what can be glossed over and discarded.

See what I’ve demoed on my Reviews Page!


The Main Reason

The biggest reason to trust me is that I’m just like you! I do an exhaustive amount of research before I purchase anything, and don’t stop searching just because I own a product. I keep up with trends, reviews, blogs, and stay immersed in this niche because I’m truly passionate about it and care a great deal about it as well.

My Goal is to Help You

In addition that, I receive emails, comments, and testimonials fairly frequently from people thanking me profusely for what I do here, and for making such great recommendations specific to their need. It’s refreshing to be able to connect with people from all over the world and help them make the best decisions possible with regards to studio equipment and anything music production related! I truly love and enjoy conversing with you all, because I’m passionate about this stuff!

With that let’s get into the meat of this thing!


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 and M50x’s ear-cups rotate 90 degrees. The original M50’s rotated 180 degrees.
  • Both are closed back, Circumaural.
  • Both have detachable cable features.

Differences

  • Price. The 50x’s are more expensive.
  • The M40x has a different design. It’s a bit more minimalist.
  • It’s a little smaller in size than the M50x.
  • The M40x is much lighter than the 50x, and they feel even lighter on your dome piece.
  • The 40x’s have softer cushions, making them more comfortable.
  • The bass on the 40x is tighter and more integrated into the sound, whereas with the 50x it’s a bit more in your face/hard hitting. The 40x still retains it’s V shape but is overall less aggressive than the 50x.
  • The M40x’s have a little less bass, a flatter response, and a bit of a tighter Soundstage. What is Soundstage? The M40x is a more accurate can overall.
  • The M50x’s come with 3 cables: 1 coiled, and 2 straight of differing lengths (1.2m & 3m) The M40x’s only come with 2: 1 coiled, 1 straight. They are both also extremely long, which many people have complained about.
  • The M50’s possess a much better build quality. The 40x’s have been known to snap around the hinge area. The 50x’s are more free in this regard to move around.
  • 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. What is Headphone Impedance?
  • The M50x’s are heavier, coming in at 285g as opposed to 240 for the 40x.
  • The 50x’s have clear and classy indicators of 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.
  • The M40x’s only come in black, while the 50x’s come in different colors (Subject to change).

I would say if you’re more of a critical listener, and prefer a more balanced sound, the 40x is the golden ticket. Think you would prefer it?

The 50x is for the more casual listener, with a more immediately accessible and enjoyable sound. It’s a fun experience for sure! Interested?

Introduction


I’ve since given away my M50’s, 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. If you’re interested in the differences between the original M50 and 50x, there aren’t many, but here it is: Audio Technica ATH M50x vs. M50

Learn more: Closed back vs. Open back headphones.

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 like 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.

That said, the 40x’s are a pretty similar sounding set of cans to the 50x, but with some subtle differences that you should be made aware of.

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


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 remain free like Nakey Tommy Pickles.

Lol, Chuckie looks mad bro

What this freedom enables is a preventative measure from the headband snapping or cracking around that sensitive point where the ear-cup meets the 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 though. This was a 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 it’s 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-

What about comfort?


Comfort


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 clamp force is a bit tight, similar to something like an HD600.

Learn more: Sennheiser HD600 Review!

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. 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. 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 tolerable because I do enjoy the sound so much.

COMFORT SCORE: B/B+

How do they sound?

Back To Top


Sound


The sound of the 40x is definitely not neutral, but it is fairly balanced, all things considered.

Bass

I would say the mid-bass here has a bit of a rise/bump in it, which can sound slightly unnatural at times. There’s a slight fuzz to tracks which can kind of distract from the mids as well as the overall clarity of the sound as a whole. It feels like some type of thin cobweb or something. I’m kind of nitpicking however, as I find the character of the low end to have a lot of nice impact and clarity.

To be honest, some will call this a bass head can and others will claim it for reference. I think the truth lies somewhere in the middle.

I probably would not rely on this headphone as a primary mixing can, but I also wouldn’t toss it aside if it was the only thing I had lying around. I do prefer the V6 for that as far as closed backs are concerned, and this 40x more so for general listening purposes, which it really excels at.

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.

50x comparison

The mid-range in comparison to the 50x is definitely more natural, while the 50x’s is a bit more recessed. The 50x is your typical V-shaped can, and should be treated as such.

Treble

The treble is mostly very good, with a small concern. They can sometimes sound slightly metallic and essy, but it’s kind of faint and you may not even notice with the majority of tracks. Still, 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 70 headphones and kind of have a good idea about how stuff sounds in relation to another.

For example, a particular high hat I used for this one 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.

SOUND SCORE: A-

What about Imaging?


Imaging


One thing that the 40x really excels at that you wouldn’t think is Imaging.

These have a way of separating instruments and vocals very well, with a mostly natural sounding character and some nice Timbre. What is Timbre?

I definitely wouldn’t sit down and expect these to sound marvelous with Jazz, but they can work in some circumstances like good source files, etc. I think the Bass is too heavy for such an affair, but we’ll get into Genre in a bit.

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 here.

Will you need an amp?


Amplification


They are very pretty efficient at 98dB, but I still may consider some sort of amplification as it will help with clarity and resolution to a great degree.

With that said, I wouldn’t really worry too much about which Amp/DAC combo or Amp + DAC (separate) you go with.

Here are some good options to consider:


The Budget Homie


FiiO E10K.

Listening right now with the E10K actually, and it’s hard to believe this puppy is under $100. For instance, on the track “Over Sensitive” by Chelsea Jade, it’s 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 into your phone. The E10K provides a ton of clarity, crispness, and detail that really does impress me considering how cheap and small this thing is. It’s good! You like! Comes with coaxial out, line out, and USB input for your PC/Laptop.

A Step Up


Audioquest Dragonfly Red

Audioquest DragonFly Red Review
Dragonflies are found outside, right?

I really like the Dragonfly as sort of a step up from the E10k. You’ll notice a bit better clarity, Imaging, and Soundstage, but the differences are fairly subtle. What’s great about the Dragonfly is that it’s much more portable and convenient. You can literally stick it in you pocket and take it anywhere!

If you do a lot of traveling around like me, this will prove to be very valuable as you don’t have to worry about wires, or the size of the amp and DAC. Just toss it into your laptop bag and away you go! Once you reach your destination, whip it out and stick it in the USB hole. If you desire to pair it with your phone, that’s cool too. You’ll simply need this adapter which is very cheap and gets rad reviews.

I wouldn’t worry too much about Amps outside of these two great options as far as this headphone in particular is concerned.

What types of music will these do well for?

Back To Top


Genre Pairing


Well friend, you know what I’m about to recommend. Anything bass oriented with these will shine.

I’m enjoying them right now 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.

So what’s the Final Grade?

Back To Top


Final Grade


I would probably give these a solid A, maybe A- because of the sometimes essy treble and slightly over-exaggerated bass.

You may think that those are too serious of problems for an A, but they aren’t. They’re minor issues that in no way detract from the wonderful overall experience that these headphones provide.

What’s the Final Word?

Back To Top


Final Word


After owning both for a significant amount of time, I believe the 40x to be a more realistic representation of the music. It’s still got a lot of bass impact, but it’s more “true” sounding than the 50x if you will.

The 50x is definitely a bass-heads can, and possesses the typical V-shaped response: Lots of bass, a recessed mid-range, and a sparkling treble. I owned the M50 from January 2013 – April 2018, so I have a pretty good idea of how it sounds. I ended up doing a giveaway which you can check out in this article on the HIFIMAN Sundara.

Anywho, it’s not much different than the 50x which I have also demoed in the past.

If you’re looking for a more honest sound signature, the M40x is phenomenal, and does come across as more balanced and true to life. I consider it a fantastic all around solution that will handle most any type of music you throw at it.

SEE THE M40x FOR YOURSELF ON AMAZON!!

As mentioned in the open, the 50x is for the more casual listener, with a more immediately accessible and enjoyable sound. It’s a fun experience for sure! Interested?
