Build Quality
The build quality of the Sennheiser HD650 is roughly the same as the build of the HD600.
In other words, very good.
There aren’t any glaring deficiencies in either headphone.
The 650 is lightweight but doesn’t feel cheap.
It simply feels economical.
Its weight is perfect for long listening sessions;
it doesn’t tire you out at all, and the clamping force, once broken in, is perfect.
The padding is a soft and plush velour for the ear pads and a foamy type of material for the headband.
Like the HD600, almost every part on the 650 is replaceable.
The headband adjustment is somewhat flimsy, but it doesn’t feel cheap.
The material is simply thin and unique.
It’s not a mechanism I’ve ever seen before.
The earcups move a little bit, but they don’t rotate inwards and outwards outside of a couple of inches. Just enough to get a good fit which is fine.
These will primarily be your studio headphones, and really shouldn’t meander outside very often (if at all).
The Wire
It comes out of both ear cups like the HD600, and it’s the same type of connector.
The difference is the connectors on the 650s are slightly larger and much easier to insert in and pull out.
Unlike the 600’s connectors, they aren’t color-coded.
The 650 terminates in a 1/4″ jack while requiring a 3.5mm adapter.
All in all,
the cable feels much more solid than the 600’s cable. It’s thicker and has more girth to it.
But, the trade-off is that it’s a 1/4″ connection with a 3.5mm adapter.
I personally would rather it be the other way around, but your mileage may vary.
All in all, it’s a well-built set of headphones that should stand the test of time without question.
Build Quality SCORE: A+
What about Comfort?
Comfort
Comfort is phenomenal.
As mentioned above, these play really well for long listening sessions, and will not fatigue you in any way.
They fit securely on your melon, and the cups themselves leave ample room for your large, Ross Perot-sized ears. 😛
They are oval-shaped and contour nicely to the natural shape of the ear.
The driver is also just far enough away from your ear not to obstruct or otherwise hinder your listening experience.
Do keep in mind the clamping force at first – an almost unanimous nitpick amongst audiophiles and enthusiasts alike.
The HD600/650/6XX series of headphones will hug rather snugly on your melon at first, but they do open up over time.
Still, you’ll likely come to really love the way they feel.
I’ve likened it to receiving a warm hug from an old friend, and I still feel that way to this day.
In fact, the 600 series ranks rather highly on my Most Comfortable Headphones Of All Time list, and you’ll likely agree – there are simply not many other headphones on the planet that feel quite as good.
COMFORT Score: A+
How do they sound?
Sound
This is Pleasantville all the way, man.
The sound isn’t dull, it’s just very laid back.
This pretty much confirms all of my research prior to this updated review.
The sound is warm.
It’s lush.
It’s fairly thick like that girl from the gym you have a crush on.
DUMMY THICC.
The best way I can describe the HD650 is that the sounds emerge distinctly, forming cohesively according to a strict process.
It’s much like how a plant grows or a person develops over time.
Sound does not randomly appear as with lesser headphones but instead is given ample room and space to articulate itself fully, with an impeccable sense of timing and decay.
Instruments and vocals are given free rein to dwell and express themselves thoroughly and completely.
Bass
The bass doesn’t roll off quite as much as an HD600, which is kind of cool.
It’s still in no way muddy, overbearing, or out of line.
This is an articulate, textured affair and simply knows its place.
If the song calls for more, the HD650 will reveal it in a tasteful manner.
For the most part,
the bass sits down in the mix where it should, and adds to the mix rather than hinder it.
It is a well-known fact that the 650’s mid-bass is a tad more forward than the 600’s, and this is certainly true.
You’ll notice a bit of extra weight/bump/thump, but it’s fairly subtle at the end of the day.
Mid-range
Of course, the mid-range on a Sennheiser is going to be fantastic, and this headphone is no exception.
Detail retrieval is phenomenal as well.
There’s so much clarity that you miss out on with other lesser headphones.
Echoes especially give the song that added depth and intimacy that we all love.
One of the most notable aspects of the mid-range is the 650’s ability to render vocal passages with stunning accuracy and realism.
In listening to Rage Against the Machine’s “Bullet in the Head” I was taken aback at how different Zack De La Roca’s voice sounded.
It was almost nasally as if he had a cold.
It was revealing and strange all at once, with almost uncomfortable clarity.
Likewise,
instruments and seemingly extraneous sounds really came to life as well and took on a personality all their own.
Rage has this uncanny ability to make a guitar sound like a torture device at times.
With the 650 those traits are exemplified in a way that demands your attention.
It’s like the sound is so crystal clear that it takes center stage for a second.
Treble
The treble is a nice change of pace from the usual, overly bright, metallic, sizzling treble that you’re going to get with 95% of headphones.
This treble is darker, and some call it veiled. What is the Sennheiser Veil?
I will admit, these sound a lot livelier with the gain switch on high out of my Oppo HA-2.
What I love most about a headphone like this is that it just never annoys me. I can sit down and listen to it for long periods of time without taking it off.
Every sound is intricately placed and I think that is what sets it apart from other cans.
You really begin to hear music rather than just feel it.
There’s something about both the HD600 and 650 that make you just want to sit there and listen to music for as long as possible.
Instrument Timbre is absolutely astonishing with certain tracks.
For instance, Touch Sensitive’s “No Other High” sounds pristine like Claire from the Breakfast Club.
Overall?
SOUND SCORE: A/A-
Why? Because I said so! Just kidding. Because they may sound a bit dull to some people.
In other words,
at times they lack a certain energy.
Let’s take a look at some photos…

How’s Imaging?
Imaging
The imaging is absolutely lovely, and may just be the 650’s best overall quality.
It’s funny, you tend to get really spoiled with these and the HD600s.
Whenever I go back to them after a long time without listening, I’m completely amazed all over again at how well they do, well everything.
Imaging, as well as Instrument Timbre, is particularly noteworthy.
Instruments and voices just come alive in a way that’s both genuine and exciting.
Whereas some headphones have that disappointing, thin layer of mud and clamminess covering the song, the 650 renders music in a way that’s wet and dense.
The word I’m looking for is succulent, like a juicy, tender steak from your favorite restaurant.
There’s no rivaling that sensation once you experience it firsthand.
There’s a certain tenderness that the 650 has and it’s unmistakable.
It’s almost like that girl we talked about before; you just know she’s the one when you see her.
You may have pushed aside hundreds (if not thousands) of other girls before you met her. The answer was always “No” for some reason or another.
But this time it’s different.
You don’t look for excuses or reasons to write this girl off.
You don’t look at her as an object, but rather as a real person with feelings and emotions.
You respect her in a way that can’t be measured, quantified, or even understood.
It’s simply felt on a level that’s somewhat foreign to you.
You may not even know her that well.
Doesn’t matter.
You feel something different when she’s around.
She’s not perfect, but her imperfections are what make her so.
She’s like a beautiful painting – you may not like every single color the artist used, but you really don’t have to.
When you stand back and consider her as a whole, she’s breathtaking.
All of the colors come together to form a cohesive, stunning image.
Her personality, spirit, mind, body, physical features, drive and ambition, sense of sophistication, professionalism, and the list goes on.
The 650 is similar in that regard.
Taken as a whole, it’s a nearly perfect headphone.
It doesn’t do everything 100% right, but it comes darned near close my friend.
The Other Gold Standard.
Pros
- Extremely accurate and transparent, with a forward and engaging mid-range + a tight and authoritative bass response. The bass, rather than being bloated and loud, is accurate and precise. You will be able to hear the tone of a kick drum as well as different textures in frequency.
- Not too picky about which amp you choose to pair with it. Sounds pretty fantastic with most amps.
- Very versatile in terms of genre, handling a wide range of musical styles. Rock music is its strongest suit.
- Comfort. The velour ear pads make it so you can wear these for hours and not get fatigued.
- Replaceable parts that ensure longevity out of your purchase.
Cons
- Too smooth. Like Fonzie except not, these headphones are so chill that they may make you fall asleep!
- Treble is lacking a bit. This is the “veiled” sound that people talk about in regard to Sennheiser headphones. Somewhat lacking in air and harmonic content.
Will they need an amp?
Amplification
The great thing about the HD 650 is that it isn’t too picky about which amp you choose. How to choose a headphone amp!
At 300 Ohms Impedance, it does need one to reach its full potential.
That said, it’s also fairly efficient at 103dB Sensitivity and thus not that hard to drive. This is one reason why many pairings theoretically work well!
Video Discussion
Don’t forget to leave me some love! <3
If you need help deciding on something, just let me know down below in the comments!
As for my top recommendations, I mostly lean towards the ATOM, K5 Pro, or Zen for the bulk of my recommendations to people just starting out.
Genre Pairing
As alluded to in the open, this is a very versatile headphone that handles a wide variety of genres including:
- Rock
- Jazz
- Classical
- Hip-Hop
- Soul
- Acoustic
Its bread and butter are most definitely Rock music.
This is in part due to the mid-range as well as the bass not drowning out other frequencies.
The treble also has a lot to do with it.
There simply aren’t many genres that I don’t like with these headphones.
The only real exception is Jazz.
It’s not that it sounds bad as just maybe it’s not open-sounding enough.
This was an issue with the HD600 and unfortunately, the trend continued here.
Final Word
Since 2003, It’s been one of the most beautiful-sounding headphones around.
It’s extremely accurate, has a really great mid-range, accurate bass, and is very comfortable over a long period of time.
The treble is lacking a bit in the upper registers, and it has been criticized for being a bit too smooth, almost lulling you to sleep.
However, what you are getting with these is a brand-new music collection.
Why?
Because they revolutionize everything you own, plus the music you haven’t heard.
It’s like hearing all of your old favorites for the first time again.
You will start to notice things in music that you never knew were there.
This is one of the best things about the jump from entry-level to mid-fi.
A headphone like the HD650 makes you realize what you were missing!
Feels good, man.
Hearing the 650 is like kicking back with a glass of fine wine and taking a relaxing bubble bath.
It just feels so good man.
While the HD650s are phenomenal headphones, I think the original HD600s outclassed them just a smidgen.
They are snappier and livelier, and their bass doesn’t slam as hard but remains more textured and in its place.
You actually enjoy the bass more because of its quality over quantity.
The 650s aren’t muddy in the slightest, but: side by side you will notice a difference in bass quantity. The 650s have more of it, and it’s a bit thicker and syrupy.
Now, you may actually prefer that!
The important thing to remember about these guys is that they aren’t all that different. There are some differences there, but they are rather subtle.
If you’re into saving money, I would probably just recommend the 6XX, as it’s a fraction of the price and in my eyes, sounds like a perfect cross between the somewhat overly syrupy 650 and colder, more clinical HD600.

A great deal of technical information, much of which is over my head.Loved your description of what good headphones should be, as if the band was there and the music from outside your head. From this I can tell that I’ve only used low quality headphones in the past.I hope someday to experience the phenomenon you describe but for that kind of money it’ll have to wait.
Hey Jack!
Thanks for the comment! I agree, a purchase like this should be thought about for sometime.. however the 650 is more than a worthwhile investment. I myself am highly considering it as my next studio piece. Appreciate you dropping by.. Take care..
-Stu
Hi Stu, what a great article! So much detailed information, and also the videos are very professional.
I used the Sony MDR-7506 and I thought that they were very professional, but now, reading your post, I wonder how these Sennheisers sound… The price is VERY different, so the quality must be too!
But can I ask you, how can good quality headphones have such different prices?
I mean those Sony’s are not cheap headphones, and to my ears (I’m not a pro, but I produce some music with my PC and in the past recorded instruments with my band) they sound good. Is the $350 difference really worth it?
Hey Matteo!
Funny you mention the 7506’s. I had them for a while and really liked them a lot. They aren’t without their flaws, but they provide a very analytical, almost cold sound. They really improved my mixes ten fold. The problem? They are a bit harsh/shrill in the treble range, and the ear-cup on mine fell off. The ear-cups also peel like no-ones business. I think in another article I mentioned it was like aged sunburn peeling. Lol.
I still recommend them because they’ve become an industry standard and the sound is quite neutral overall. They do have a bit more bass emphasis than necessary for reference headphones, but it makes them an enjoyable listen for casual tunes and what not.
As for your question:
How can good quality headphones have such different prices?
This is a very loaded question, but I want to clarify.
It really comes down to the sound, the comfort, and the overall build. When the sound is very close to neutral, but clear, accurate, and precise.. the value goes up. Imagine if you could hear everything going on in a track, even the stuff you never knew was there! That’s what it’s like having higher quality headphones. When nothing is muddied up or indistinct, you have an almost religious experience. I’ve seen people give amazon reviews claiming they were brought to tears with a good pair of cans and an amplifier. It happens all the time, and a good set will revolutionize your music collection. The sound-stage is a huge factor here. People love it when they feel like the music is surrounding them, not unlike surround sound speakers. It gives the cans a more 3-d like quality, and you can really start to place exactly where musicians and instruments are on stage. What is Soundstage?
The build also increases value. A lot of time you may hear someone complain of poor construction in a cheaper set of headphones. Well, you get what you pay for, but there are exceptions of course. Generally the higher in price the better the materials used. Comfort is very similar as well. Pretty much all of the open back headphones use velour ear padding, which is extremely comfortable, and a lot more so than pleather or something similar.
Lastly, longevity comes into play. Materials break down over time. That’s an unavoidable fact. However, if the components used are replaceable but still last a long time, you have an exceptional product. The Sennheiser HD 600 and 650 are perfect examples of this concept. They can literally be taken apart to the core, and nearly every thing inside can be modified, fixed, or replaced. Given proper care, these headphones could last you the rest of your life.
All this being said, I do recommend the HD 600’s over the 650’s. The reason:
1) Signature. You basically are paying $100 less for a superior sound. This is arguable, but most people will agree, the 600 is more neutral, and has a crisper sound. The 650 borders on TOO warm. Like too much of a good thing. It does have more bass though, and that may attract a different demographic. Regardless, both headphones are phenomenal. Check out my Sennheiser HD 600 Review!
Hope I answered all of your questions! If you have any more, let me know!!
God bless,

Very well written page. Thanks for sharing and giving these important tips. They are definitely helpful for newcomers and aspirants looking into having a great musical career path.
Your website will definitely be bookmarked by many musicians and look forward to check often. My instrument is keyboard and this instrument does need other accessories to build a proper studio and your site will be a guide for me for sure. Thanks.
Hey Hamza!
Thanks for dropping by! What kind of keyboard do you have? I’ve only had one since I’ve had a studio, and I was a relative noob at that time. I didn’t even really understand how it communicated with my computer, or even what I needed to do for it to produce MIDI that I could then use for a song. It was fun to mess around on, and I may invest in one in the future.
I mostly sample with the KORG padKONTROL, and it’s been a workhorse for me since 2007. You’re right though, a home studio isn’t just one piece, although it starts with that! Check out my How to build a home studio guide when you get a chance.. and Contact me for any reason as well.

Great Article.
I used to have my own studio and a pair of 600s.
I think they are the most “honest” phones I have ever experienced. In studio work, that is what you need. I like the fact that there are those small differences in attack in music, it makes it more human.
I was surprised at the frequency response you quoted: 12 Hz is subsonic and anything over 22,000 Hz is weigh above most peoples range. They say you can “feel” the touch of a triangle up there, but 39,000 Hz Wow! That’s in the region of cats and dogs hearing.
If I had to choose, I would definitely go for the 600s but have a pair of 650s for general listening. My hearing has deteriorated with age anyway, but I still love the presence of a good pair of phones.
Thanks Happy!
I really like the 650’s for general use as well, and do find them the more “enjoyable” listening headphone out of the two. The 600 is definitely for reference as it tends to be more sterile, while the 650 smooths out the rough edges of the sound, akin to something like sandpaper to wood.
You’re right; companies tend to over-exaggerate the FR response but like you said we really can’t hear much over 20kHz so it’s essentially useless.
Thanks for helping clarify the differences for people who may not know!!
Blessings,
-Stu
Hey Stu,
Long time no see. Not too long ago, I was contemplating whether I wanted to purchase the Sennheiser HD 600 or 650. Plus, the possibility of upgrading my headphone amp/dac setup. After spending some time listening to Z Reviews’ sound demos of both the 600 and 650s and other in-depth analysis, I decided on the 650. As an aside, I was really torn between the two. From what I heard, the 600 were slightly more neutral and intimate. Whereas the 650 seemed slightly spread out in sound plus being somewhat more resolving. One of the other deciding factors were that pricing of both headphones were very close around purchasing time. Much closer than the 100 dollar price gap as listed on Sennheiser’s website.
Funny enough, the price of the 600’s on Amazon dropped below $300 in fact closer to $250 less than 2 days after purchasing the 650’s. From my research, I did come across the subject of the “Sennheiser Veil”. Which came about partially when the 600’s came out during the mid-late 1990’s. In that the 600’s were considered a departure from the norm of high end headphones having a bright top-end. Then there’s the supposed differences between black driver and more recent silver driver 650’s. After having the 650’s for approximately 2 weeks, a few adjectives come to mind when describing the 650’s. Effortless in regards to sound, startling “natural” tone/timbre, and versatility. The 650’s really shine with very dynamic music. From my perspective, the 650’s are equally adept in critical and causal listening circumstances. While it won’t bite one’s head off with sub-optimal recordings like Beyerdyanmic DT880’s or AKG K701/702’s, it won’t mull over compressed recordings.
As an aside, I demoed the 650’s on my FiiO E10K. While they did reach more than adequate volume levels; it did not push them with as much authority as I would have liked. I dropped coin in a TEAC HA P-50 SE headphone amp/dac. While it may not be the permanent fixture for the 650’s, it does drive them with aplomb plus good headroom.
Anyway, keep up the good work Stu.
Hey man great to see you back!
That’s funny; I’ll have to try the E10K out with the 650 again. I demoed them for a quite a while (a few weeks) and found that with the gain switch on they got really loud so I’m not sure. I do agree now that I think about it though – the “authority” isn’t quite there and I do see what you’re saying. The 650 however is such a laid back headphone but your assessment of the sound is spot on. It’s a headphone that I want to recommend to 99% of people (maybe even 100%). I don’t think there’s another headphone out there that so perfectly understands the needs of the majority of people as well as this headphone. Everything about it is effortless as you’ve stated. In fact, the Timbre is what I was most impressed by; there’s a level of grace that’s simply unmatched.
I kind of do prefer it over an HD600 because the 600’s mid-range can be very irritating at times although it’s still a phenomenal headphone (especially after putting it down for awhile and coming back to it).
Did you happen to see my article on The Sennheiser Veil? I want to go back and add some things to it.
Thought about it some more and I think as a permanent fixture you should definitely get an Objective 2 from JDS Labs. I can’t recommend it enough as it’s going to create some nice air and spacing, but come across completely neutral and retain all the great characteristics of the 650’s sound while making it seem borderline incredible.

Let me know what you think!
Hey Stu. Long time no see. Previously, I commented on purchasing the Sennheiser HD 650 plus initial impressions. Fast forward 6-7 months, my thoughts have largely unchanged. Especially in regards to how effortless they sound. Anyway, one of the things I have noticed overtime is that the right ear pad for my headphone has in some spots flattened. I was previously aware of the fact that pads on these and the HD 600 can flatten overtime. The left ear pad remains fairly stiff though very comfortable without being a vice grip. While there has been no detectable effect on overall sound, it’s somewhat odd that the right ear pad is more flat than the left though not like a pancake. Additionally, I do have a fairly large head which might play a role. My question to you Stu is how have the overall condition of the ear pads on your HD 600 have changed since owning and using them? Keep up the good work, Stu.
Hey man great to hear from you again!! I’m looking at my pads right now on the 600 and upon close inspection I have the same issue!! Lol I never noticed that before until I really examined it. So my left cup is actually a bit more flattened out than the right one. Keep in mind I don’t use these everyday, but I have been using them more lately. I actually tried to fluff them up a little but to no avail. Fortunately for us, the pads are replaceable but I don’t feel as though I need to right away. I will take a picture and send it to you over email. Also it’s interesting you mention your head. Mine is actually more narrow width wise but longer vertically. In all honesty I can’t think of a good reason why one pad would flatten out sooner. That’s kind of strange. Thank you for your nice comments!
In my case, my head is a bit longer vertically speaking vs width. That being said, I don’t have a melon like Mr. Potato-head 🙂 Anyway, I found it intriguing on how as aforementioned my right earpad/earcup is more flat vs the left one. The best analogy I can give pertaining to the earpads are that the right one is more springy whereas the left earpad is closer to how the pads were fresh out of the box. More of late, I tend to use the HD 650 it as my daily driver for multiple purposes. Listening/analyzing music, watching films, etc.
Lol this girl at Walmart once told me to “Shut up with yo apple ass head” Lmao. When I used to grow my hair out it made my head look weird like an apple I guess. 😛
Anywho, did you get my email? I love the 650 for Gaming and movies actually. I think it has better Soundstage than an HD 600. The image seems to be wider and more immersive. But: an ifi xDSD or xCAN brings out the best in the 600 in terms of staging width. I found it to be a great pairing.
Thanks for (as always) honest, professional and entertaining review. I am also a very happy HD650 owner. I’d like to add that switching the pads to Dekoni velour makes a HUGE difference in sound: soundstage gets wider and deeper, bass gets tighter and stronger (while not detoriorating mids and highs). Try it for yourselves, folks!
Hey Marcin!
Thank you for the kind words 🙂
I don’t have a 650 but would love to try that if I ever do get one here again. Your comment should help others who read it though so thank you!!
