Ah, such beautiful detail shots. 😍 Thanks for this video! We're liiikely biased but would agree... STILL one of the best headphones, no doubt.

My OG 1997 HD 600 is still going strong. Everything but the driver and cup assembly has been replaced, and should last another 25 years. 😊

Probably one of the safest buys in headphones. Both in terms of sound, and also in build and longevity

Another hugely underrated point about this line of headphones is the sheer longevity of the design and build, save for the padding (which is easy to replace and has ample availability in basically all markets). I have a second-hand, original HD 580 that is quite literally a year older than me and has been in day-to-day use for most of its lifetime, and still is. As with so many other things, we have a word for this in Germany: unkaputtbar 😌 Now compare this to Hifiman's spotty QC for the Sundara as well as frequent product iterations/subsequent improbability of spare parts into the distant future, and that alone is another massive additional selling point.

Its staggering that 25 years ago they came out wity a headphone so well tuned before any of current target adherence stuff even existed. Kinda sad there is so few headphones today that are so well tuned, while you can get iems tuned to practically every adherence target there is.

Looking forward to the comparison video!

Owned this 15 years ago when I was into headphones and it was my fav after trying many of them. happy to hear It’s still considered amazing. Must sound sick with the new age dacs and balanced amps!

I've had mine for 20 years now (and I bought them used, production date is 1997). Still going strong.

I just got some for mixing and mastering. Cant wait to get them!

I had a bit of a wild journey with open-backs. Starting at the X2HR years ago, before taking the jump to a Sundara and HD650 combo in 2022 (wanted to try them both), then acquiring an AKG K702 (just wanted to know what soundstage was like), and then selling the Sundaras in favor of Meze 109s. Eventually I picked up an Edition XS (Did not like the Sundaras too much, but missed certain planar characteristics), which I enjoyed a lot more than the 109 Pros, and then finally a pair of HD600s to see what they were like compared to HD650 and my other headphones. I had always used the HD650s as my "everyday" sort of headphone, but really only attributed to the comfort, I never really wanted to use them over Ed. XS or 109 Pros, I was expecting the HD600s to be so similar to 650 that they would also fall into the same kind of use case for me. But to my surprise, I enjoyed the HD600s tremendously. Compared to the HD650, it was as if the 650s had the stage curtains closed between you and the performers, while the HD600 was presented with them wide-open. Suddenly I started liking an HD6** pair for more than just comfort, and began questioning why I had spent so much money on headphones when the HD600s at $300 were my preferred sound signature, I think mid-range just matters more to me than low-end and treble. After much deliberation, I finally went through the effort of selling the K702s, 109 Pros, and the HD650s, ending up with "just" two open-back headphones. The HD600s which I use nearly all the time, and the Edition XS which I pretty much use exclusively for gaming, good orchestra recordings where I want some more staging, and high-energy music where bass makes a difference. I think they are a really good combo, however, while I can see myself eventually upgrading my Edition XS to a more expensive Hifiman or maybe even Audeze, I think the HD600s are here to stay.

I'd love to see a review of the HD 580 Precision. Obviously it hasn't been in production for years, but I think it would just be a very entertaining video. I'd love to see it included in the comparison video as well as the HD 58X!

Proud owner of a pair since 2000 and they are still going strong. The pair stayed in the box for 7 years in an area of the apartment subject to fairly large changes of temperature (from 12°C in the winter to 35°C in the summer), but I only had to change the pads and it was good to go. The plastic shows no signs of cracks despite the pair falling on the floor from the top of my PC tower on a regular basis. It's just a good sounding, no fuss headphone.

In 1999 I had no idea what I was ordering without hearing first. I still have the same one and have gone through 3 sets of ear cushions and a couple head cushions. I think at least two sets of cables in addition to a set of Oyaide silver ones I got when I lived in Japan. I still enjoy them a lot! The other main set I use is a LCD5 for a little over a year. Currently fed from a RME ADI 2 Pro FS. Oh and currently have Dekoni pads. Top tier in my book. Thanks for another great video. One regret is I wish I still had the original box.

I got hd600 recently. The amount of detail is unbelievable!

I literally ordered the hd600 today after receiving some advice from listener a few days ago.

Brother! this type of information videos is what I absolutely like! NO background annoying soothing/music

great content. Succinct well articulated and super informative. Fabulous

Next year will be 10 years for my pair. Still works and still is absolutely amazing. I got it for $350 at that time and it still is worth every penny even back then. It really is great for more vocal music and footsteps in games. I love them.

Thanks Much !.......for the review.

If you can get past the boy racer mag wheel styling, the FT3 by FiiO is a really nice example of an open-backed headphone with a balanced sound signature and sub bass extension. I love my HD600's, but I haven't been reaching for them since i got the FT3's. Incredible package for the price, too. Not sure why more people aren't talking about them.

Old but gold, love mine, perfect match for my chord mojo dac 👍

How do these compare to the PC 360? I plan to replace them with something similar and am considering these.

Great review is the imaging good on these??

Man this guy has knowledge. Thanks for all the information!

Thank you for the detailed review! I wonder if you could provide the info for the amps that you use together with the headphone?

You're not kidding. I bought one of these shortly after they came out, just before Y2K, and they are the only audio componant that I still have and use from back then. (Currently my top headphone is the Audeze LCD-5). For exceptional midrange -- think recording or mixing a Jazz vocalist, acoustic instrument ensemble,, that sort of thing -- they are shockingly accurate and translate exceptionally well to any high-end playback system. If you like music where pounding deep bass is not in the mix, these are hard to beat even at a way, way higher price. I'll be interested in your coming comparison!

got them after watching some of your reviews and how often you mentioned them as one of your all time favorites... i use them for mixing and mastering (classical, jazz and world music) along with a pair of Audeze lcd-x 2021, powered by a Rupert Neve RNHP Precision headphone amplifier. I have to say i prefer to use the Sennheisers for critical listening! they are that good! sure, i won't get the level of detail and bass the Audeze offer (they are also awesome for studio use, no question!) but being so intimate and neutral on the mid frequencies is a delight; you just have to dial your mixes perfectly to sound great on the sennheisers! ...and once you achieve that, chances are your mixes will sound GREAT anywhere! they are Not fatiguing and ridiculously transparent! thanks so much for what you do... still would like you or any of your colleagues to review the Neumann NDH 30 under that critical listening (professional use) perspective! maybe one day?

I got these on an open-box sale on your website and I couldn't be happier. $130 off. They were brand new, someone cut the seal on the box and didn't even take them out! 10/10 Would buy again.

The Sundara was my 1st dive into hifi last year. I recently got the HD600 and it's been amazing. When paired with my Fiio K9 and Shanling M3 Ultra, I can't get over how good it sounds and how well it scales with my gear. I can see why it has been around for this long. Great buy and an easy 1st recommendation!

Hoping you will compare the HD 600 with Neumann NDH 30 (for what i've read, Neumann, being part of Sennheiser, took a lot from the HD600 &650 to produce the NDH 30). If anyone owns both, would love your take!!

love my marble blue HD600 have been using them for gaming for several years, and just replaced my earpads cause I wore them out. I always recommend it to my friends all the time.

Hello, great review - I'm looking for a more V shaped sound as you mention here - what would you recommend for that?

Hi, I tried the HD600 at a local store. It was balanced, but my right ear hurt from the treble, also, I felt like the HD600 was a little bit grainy. Is this normal, or maybe I tried a faulty unit? I also tried the HD650 which was not grainy and did not hurt my ears, but it wasn't flat and the vocals got pushed back. I was also thinking about trying the AKG k361/371, but read/heard that the perceived frequency response on this models changes noticeably depending on the position on the head, compared to other headphones. I need it mainly for mixing (closed or/and opened), and any insights will help me. Thanks!

Had mine for about 25 years and never desired any other headphones I've tried over the 600s. I've replaced pads of course, also the cables and drivers once. That's another nice feature, easy to find and replace parts. For tonal balance and detail the 600 is all I want.

Definitely in my top 3 of headphones I'd like to hear and probably own

Thank you, it has been a long time since I've listened to my HD600's. I've pulled them out today to listen to them. Two points, I feel worth mentioning. 1. TUBES. These things do fantastic when tubed. 2. They scale very well. Their flavor changes a bit from amp to amp, which is fun for an audiophile who likes to change the sound a bit depending on their mood.

I own older HD580s black silk version, they are most expensive headphones in my collection and I love how it is so old, but still so good.

This is hardly a mystery. It is still great now. And it will still be next year, and yet I'm sure it will be revisited by someone by then. That's a sign of a true legend.

Any recommendation about a good dac/amp combo for HD600? Thinking about Mojo 2 but too expensive? Which do you prefer? Thanks

I bought HD600 more than 10 years ago and this is still my main daily driver. Definitely the BEST purchase I've ever made. Purchasing of a HD-25, my go-to headphone for DJ gigs for years, can get close, but nothing else.

Great Review. I have one question and it's a bit nerdy. I have a pair of Bose Soundlinks that I absolutely cannot get the earpads replaced. They have a groove that I can't get the pads into. I've seem many videos' that show that the Sennheiser pads just pop into place with a little pressure. I just want to confirm this. Ready to buy but don't want to spend $300 if I'm going to not be able to replace the pads. Thanks much for a response. Much appreciated.

Thanks for this, are the LCD-5 & MM-500 not the HD 600 but with full bass extension?

Love your videos. Always articulate and thorough. Would this be good for KZfaq podcast live streams as well as video editing? Thank you.

Sorry in case this is a stupid question, but how could I EQ a HIfiman Edition XS. I listen to them using Roon on a Zen Streamer into a ZEN DAC V2? Also, can you suggest an amp for the HIfiman Edition XS, based on your review?

6:12 I’ve always love the brand form my first pair HD 414 in 1970 on up through the 6XX, and a few in between. Thank you for the great review of a great piece of headphone tech

can you share your EQ settings for the 600?

Appreciate you stating what is EQable and what isn't. So many "purist audiophile" reviewers leave that out. It's literally a way to alter the dynamics of the sound and can be extremely beneficial. Good review mate.

These are fantastic headphones, even to those of us with high-end headphones. When I sold my mid-level headphones to get my Susvara, I kept the HD600 because it just offers a great listening experience. Add Tubes for a bit of flavor, even a Schitt Vali 2 is fantastic.

For a mixer how does MM-500 or NDH30 compare? I do own hd600

What sennheiser headphone would you suggest for a good sub bass response ? Thanks

My first headphone, truly beloved, still in my collection in company with Focal Utopia, Hifiman HEK V2, He6, HD800S.

Great video but can I ask, how do I compensate for the lack of low end when mixing House Music in Ableton?

im new to all this and was wondering if the audient evo 4 mixer would be good enough for hd 600 or should i get the atoms lab amp + and would i need a dac aswell thanks in advance for the help

I love my hd600. Is there an adapter to run iem 2 prong to this 2 prong? I just ordered a Bluetooth neckband with iem plug. These headphones on the go, around the house, gaming without wires.

I have the OG HD600 plus the HD650,HD660s, HD660 S2,HD58X Jubilee, and if I only had to keep one it would still be the 600🙏 Plugged into My Tube Rolled Dark Voice they still have been my End game Listening experience. Simply Stunning Sound all around in my opinion and the Tube Amp Sound actually helps the Bass.

The HD600 is one of the best headphones you can buy regardless of price, I highly recommend them.

These are the most comfy headphones I owned. Upgraded from ATH M40x and then upgraded again to Beyerdynamic DT 1990 Pro which is a bit clampy and heavy. I can wear the HD 6XX all day with no issues.

will you be doing a review soon of the audeze mm100 headphone?

What mic are you using… I love it

Would love the 600 series comparison video out soon please 🙏

Do you have some measurements for AKG K240 MKII and how to eq them? Thanks.

So the 660s2 and the 600 are around the same price right now. Which would you buy? Note that I own the 650 and the 660s. On just about every review someone mentions how great the 600 are and so I keep thinking that I need to listen to them. Thoughts?

As a music producer these headphones have absolutely changed the game for me being able to hear compression propperly and being able to place elements are great i pair these cans with my studio monitors and dam. Just awesome. Great set of headphones

I have HD650 for music mastering. Need another pair, should i stick to 650 or grab a 600?

plesae , is HD 600 better audeze mm-500 ? is HD 600 more neutral sounding and better detailed than audeze mm-500 ?

I have a a pair of the HD-580 the predecessor to the HD-600. They are great!!! But, they are quite old, and I´m thinking of replacing them with the HD-600, or HD-650. What are your thoughts? Have you any experience with the HD-580, which by they way aren´t made anymore. Also, what are your thoughts on the Neumann, which are also owned by Sennheiser? Thanks for the great review!!!

what would be a closed back equivalent of this headphone? similar sound signature

Fellow creative professional here. Thank you SOO much for this review. I subscribed just becuase I enjoy how you explain things and you don't sound as biased in one way or another. I was referred to these headphones after asking someone for the best bang for my buck and level sounding headphones and this is the video that popped up right away. I wont be able to snag through the headphones site due to back order. I'm moving back to Europe and need to snag them ASAP Thanks again !! - jake

Do they work good with smaller devices such as smartphones or tablets?

I can tell by just the sound of your mic and the overall production quality, you have good ears. Subbed. Also, HD600s are awesome.

Can you share your EQ settings? I’m sure I’m not the only one looking one to try them

I would like to test your EQ profile for the HD600, so I was wondering if you would like to share it here?

WAY back when, I started with the HD540 reference 600 ohm, then the 580 , then the 600 (you guessed it - blue marble which I still have ) & now a 2nd new 600. I use Dekoni fenestrated sheepskin pads on the marble for added "something" for my home movie experience & stock pads on the new one for more neutrality. Do you happen to know why they would advertise 1.8 mT magnetic field strength (Edit: neodymium mags). Is that bragging OR warning? Thanks for the great vid.

This was the first pair of audiophile headphones I ever bought and they hit what I like from a sound signature position so well that since then I’ve only bought iem’s lol

Have them. Love them!!

I've had the HD650 as my baseline reference since the start of my audio journey some 13 years ago. Its the headphone that has outlasted many others which have come and gone, and scales immensely as I upgrade my electronics. 20 years since the HD650's release, itself and the 600 are timeless, highly reliable workhorses and are legendary status HPs that are worth much more than their price.

Hi! I'm in love with my 560s. Would the 600 be an upgrade? Mostly from the classical music point of view. I really like wide soundstage. Thanks

There is a headphone like the HD600 but with noticable more bass extension: The Sennheiser HD58x. It sounds close to the 600 but the bass goes down below 30 Hz at -3dB, that's pretty good, I think. Did you ever try it?

Still rock my Senns HD 380’s for that neutral output/monitoring when I’m doing video/audio edits. The 600’s are just another level of fantastic

Is the 6xx/650 comparison still in the works??

Greetings to you! Please advise the top 3 full-size headphones up to $ 700 in your opinion to purchase. Need universal headphones for Music, movies and games.Thanks for the advice! 🤝

agree, hope that near future the legendary hd600 would have some nice round looow

Definitely agree. Even though there are slight FR changes I like to make, this always sounds the most "correct" to me. My opinion always gets reaffirmed at CanJam shows when I can listen to headphones at many price points.

I just got them. My first 'real' headphones and my first open backs. I'm in love. Both bass and soundstage (which are just fine for me in the first place) can be improved significantly if you get an iFi ZEN stack, preferrably Signature. The Xbass and Xspace on my CAN Signature amplifier make these headphones sound sublime. Also, definitely recommend ZMF subpads for them, particularly the Perforated Suede ones - they improve both SQ and comfort. And a balanced cable won't hurt either, personally using the Hart Audio HC-5 Dual Senn cable.

My cable broke in about 2 years and the headphones developed a rattle. But the rattle was from hairs going inside and vibrating in the diaphragm which can be very easily cleaned off.

May I ask where I can buy that headphone stand in the beginning of the video?

Still rocking Sen’s 65O’s 🤟🏽

How would you compare the hd600 to the dt1990? I don’t know which one to get and it’s kinda a big purchase for me since I’m going to get the fiio k7 dac/amp as well

Been considering buying these, but how do they stack up with my trusted Sennheiser HD 598, the 598 cans Ive had 12 years now and they are great, are my go too for gaming long sessions, movies and certain music, I also have the Fidelio X2HR set, that one i prefer when listening to more bass heavy music, like trance or melodic techno, but they arent as comfortable as the sennheisers. What I like about both cans is that they are easy to drive, I have a sennheiser GSX 1000 dac and it has no problem with either headset, but I have a feeling the Dac would struggle with HD600 300 ohm, so not sure they for me after all, not in the market for a amplifier aswell.

I just got my HD 600 they sound awesome but they clamp on my head so much tighter than they need to be! Does anyone know which Sennheiser open-back model has a gentle clamp on the ears? Or has anyone tried to bend the headband to ease the pressure?

Are they good for all music genres?

As a happy owner of hd560s with ifo zen can (with Xbass) I'm still tempted to try Hd600s and see if and what I'm missing to my hearing taste.I picked hd560s due to praise and recommendations rather than $$$ limitation,therefore I have to test it on my own to leave it behind eventually.Will Hd600 sound better with zen can when it comes to bass lack or I"m better off the way it is now.Let's find out

What's the tonal difference between this and the 650

Have you compared them to the new HD 490 Pro yet?

I'm mostly wondering about the HD-6XX tbh as everyone talks about them and they sorta seem like the most popular in the 600 series? I'm not sure if that's true but I'm wondering about the differences between the HD-600's and the HD-6XX's because I own HD-600's and I'm wondering why people tend to buy 6XX instead?

Which iem is the HD 600 of iems ?????????

100% agree on every points you've made on these headphones. To me the biggest downside is definitely the dynamics, they can sound a bit compressed on heavy transient music. I don't exactly know how they were built but I reckon this might simply be explained by a small driver.

If you have to choose, this or the 6xx?

I just got me a pair of them. I love them imaging in gaming however is there a way to clean up the muddiness of them in the bass? I am using schiit fulla e. Would a better dac/amp help or just how they are?

Would a motu m2 be able to drive it?
