Sennheiser HD 600

  • type: open back
  • fit: circumaural (over ear)
  • impedance: 300 ohms
  • frequency response: 12 – 39000 Hz
  • material: metal grilles, carbon fiber, velour ear pads
  • color: speckled blue finish, black


What more can be said about these? Well I’ll tell you! For starters, they may be the best reference headphone that you can buy. This is across the board pretty much a consensus among-st audiophiles. I will never forget the first time I read this review on amazon. The reviewer claimed that buying the HD 600 would revolutionize not only the music you may listen to in the future, but also what you already own! It’s a very powerful concept that stuck with me. Being able to re-discover old sounds is something that is truly priceless and timeless. Everyone loves music. Imagine if the feeling you got from an old album was like hearing it for the first time again, only better and completely amazing?

That’s what these headphones provide. They provide the subtlety and details you’ve never heard before in recordings. They also reveal quite a bit of flaws in a mix/master, so be weary that these headphones were made for good quality recordings from good sources. Also make sure to purchase a decent enough amp to power these correctly. At 300 Ohms, it is pretty much mandatory. I will get into amps more a little later!


  • Great bass and low end. It’s not overpowering but rather strong, clear, and well defined.
  • Build quality is solid.
  • Gold standard for neutrality and accuracy in studio. environments. Everything sounds exactly as it is, with very little coloration.
  • Great sound-stage. What is Soundstage?
  • Airy, open, and detailed but at the same time doesn’t sound thin.
  • Velour ear pads make these extremely comfortable.
  • The price to performance ratio is virtually unmatched. Buying these may be the best investment you make, with audio equipment or otherwise.
  • Detachable cable. If your cat decides to munch on your chord, you can simply buy a new one!! 😀
  • Great mid-range, very natural (their bread and butter)
  • Great vocals, especially female.


  • Sub bass lacking.
  • A bit “veiled”, meaning the upper registers and treble frequency may be lacking as well.

What is the Sennheiser Veil?

Check out Metal571’s Review! I have the utmost respect and admiration for him. His reviews are honest, straightforward, informative, thorough, and insightful. Just the facts.

What they are good for/with:

  • Critical listening and mixing
  • Jazz and classical
  • Acoustic
  • Soft rock
  • Instrumental music

They sound good with just about every type of music, and have been called a genre master..

What they aren’t good for:

  • They are really honest and will reveal flaws in your everyday recordings. This reviewer mentioned that he was tempted to throw away all of his old badly mastered stuff. Make sure your source is of good quality!
  • These aren’t really good for bass-heads.
  • Office and portable use, etc. They will bleed sound and aren’t really made for on the go situations or where there’s the potential for disturbing others.

Amp/DAC requirements

These are going to need a good amp to deliver optimal sound quality and volume. I have done a bit of research and a few great options are:

  1. The JDS labs 02
  2. Magni/Modi combo
  3. E09k paired with the E17
  4. Bottle-head crack

These across the board are considered the go to options in regards to quality and convenience. Of course, you will encounter really high end amplifiers if you look hard enough, but for your first foray into the world of audiophiles, any of these will more than suffice. The Magni/Modi combo in particular is quite popular and of amazing quality!


Perhaps the most transparent and honest set of cans you will find. The bass is clear and precise, but doesn’t really hit as hard as some would like. Just be aware of your sound source before passing judgement on the headphones themselves. Also a good amp is highly beneficial, if not mandatory to bring out the best in these.


Sennheiser HD 650

Sennheiser HD 650 best price

best price: check amazon! | check eBay!
type: open back
fit: circumaural
impedance: 300 Ohm
frequency response: 12 – 39000 Hz
material: OFC copper (kevlar reinforced), velour ear pads
color: grey and black metal flake finish


These are some of the most accurate and well respected headphones on the planet. They are a little warmer, lusher, and thicker than their younger brother, the HD 600. They are also a bit more refined.

They are also a little less neutral and more enjoyable to listen with. As an open back model, these will leak sound so be weary of that and know that they perform best in an isolated studio environment, absent any extraneous noise and distraction.

Another thing to note is the impedance level. At 300 Ohms, these will need an adequate amplifier to reach their full potential.

More on amps a bit later!!

They take a bit of burn in time to really get acclimated, so prepare to really be impressed after around the 50 hour mark. Things start to open up considerably and everything kind of settles in. The sound becomes focused and tightly in place, which results in a very clean overall signature.


  • Extremely accurate and transparent.
  • Great body, warmth, and smoothness.
  • Nice sound-stage and imaging. You are able to place where the musicians are on stage, and being an open backed can, the sound won’t get trapped in your head and leave you fatigued.
  • A forward and engaging mid-range. helps with the presentation of the male voice.
  • Tight and authoritative bass response. less neutral than the HD 600. 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. An important thing to remember is to make sure your sound source is of good quality. These will reveal flaws in haphazard mix downs and masters.
  • 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 it’s strongest suit.
  • Comfort. those velour ear pads make it so you can wear these for hours and not get fatigued.
  • Replaceable parts, which ensures longevity out of your purchase.


  • 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 regards to Sennheiser headphones. Somewhat lacking in air and harmonic content. What is the Sennheiser veil?
  • HD 600. Many people prefer the more neutral HD 600 over the laid back sound signature of the HD 650. Others like the fact that the 650’s bass has a little more impact and weight behind it.

AMP/DAC Requirements

The great thing about the HD 650 is that it isn’t too picky about which amp you choose. At 300 Ohms, it does need one to reach it’s full potential, and a few good options would be:

Schiit Magni + Modi

  1. The JDS labs 02
  2. Magni/Modi combo (very common and a great option)
  3. E09k paired with the E17
  4. Bottle-head crack

Pricier options include:

Who this headphone benefits?

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

It’s bread and butter is most definitely for 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.


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. It’s 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. Regardless, 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 higher end headphones. They make you realize what you were missing!

Similarities & Differences


  • Both headphones are open back. Check out the differences between Open back vs. closed back headphones.
  • Both headphones have 300 ohm impedance, and do well with similar amplifiers.
  • Both headphones have a circumaural fit (around the ears).
  • Both headphones have that nice velour padding, and are very comfortable.
  • Both are amazing mixing cans in studio.
  • Both have an open, airy sound, and provide great sound-stage as well as instrument separation. Be aware that the soundstage, while good, isn’t particularly wide like an AKG model. You’re getting more of a pinpoint accurate sound.
  • Both have detachable cable.


  • Color. The HD 600 has a blue speckled finish, while the 650 sports a grey and black metal flake finish.
  • Price. The 650 comes in at a higher price point than it’s younger brother.
  • Sound. The sound of each is very similar, but you will notice that the 650’s are a little warmer & more colored. Their target audience is people who prefer a more enjoyable listening experience rather than the critical one that the 600’s provide.
  • Bass. It has been said by many that the bass hits a little harder on the 650’s, contributing to that overall more “fun” sound that we talked about.
  • Hip-Hop. The 650’s do a little better with this genre because of that slight bit of extra bass emphasis.
  • Construction. The 650 improves on the durability and overall build. The 600 is solid, but less so.

Final Word

The HD 600 and 650 are two very similar sets of headphones. If you are planning to do more mixing in studio, and need a revolutionary reference can, look no further than the HD 600’s. They just may be the finest example of an open back model that has ever been made. Don’t believe me? Out of 58 headphones reviewed, only 4 from this man’s collection received an A+ price to performance ratio.





If you prefer a more colored sound, and want to enjoy the experience rather than be too critical of it, the 650’s may suit you more. They are less analytical overall, and have been called the more “fun” sounding headphone out of the two.

  1. Thanks for this review Stu, my brother bought me a pair of (entry level) Sennheisers and I’ve been a fan of the brand ever since. I think I’m more partial to the 600s for a mixing application – the 650’s sound like they’d give a brilliant listening experience, but it doesn’t make sense to mix using these if everyone else listening to your tracks is going to be listening through below average speakers/headphones! I’ve heard before that Sennheiser’s have a warranty on all parts (or maybe it was that all parts are individually replaceable?) or something like that.. have you heard anything like this before?

    • You are totally right. The HD 600’s will most likely be my next purchase. I went from the MDR 7506’s, to the ATH M50’s.. I also have a pair of Sennheiser HD 280’s (a great set)..

      Yeah while the 650’s are amazing, they are mostly for just listening.. I have heard about the 10 year warranty/guarantee! Is this what you’re referring to?


  2. Hey Stu, in your opinion, is there any value of getting the HD650 if I already have the HD600 or are they too similar?

    • Hey Eddie!

      It depends on what you’re using them for, but the HD600 is more known as being a true mixing/reference can, while the 650 has more bass and is generally considered the headphone to get if you want to enjoy the music rather than be critical of it. The good news is that you can still mix with the 650.

      Tyll from Inner Fidelity once said that he preferred the 600’s because they were a bit “snappier” and lively. I’ve heard that the 650’s are so smooth they may lull you to sleep!

      Hope that helps! Let me know if you have any other questions..


  3. Hello Stu:
    I really like your comparisons on HD600 and HD650. Basically, I had HD600, and HD800. I have really wondered how the HD600 and HD650 differ in terms of soundstage? I mean from your comparisons. You do mention the soundstages. I guess I could say HD650 soundstage is better according to you saying we can point out where and what…

    • Hey Jack!

      It’s pretty much the same in each. Neither has a very wide soundstage like say the AKG K7xx, but you’re getting incredible instrument separation, clarity and detail with the 600 and 650. But yeah, both have pin point accuracy. Thanks for the comment!
