Sennheiser seals its reputation as the classiest name in headphones with the stunning HD600, a stylish and high-tech headphone that's exquisitely pleasing to listen to and nearly as pleasing to wear. A near-perfect mating of art and science, the HD600 uses an open, over-ear design to eliminate unwanted resonances and optimally position its large, dynamic drivers just outside your ears--so they work more like miniature speakers than traditional in-ear or against-ear drivers.

Granted, all this comes at a pretty hefty price for a headphone. But the lightweight HD600 represents one hefty value. It so far outshines other headphones in sound quality, build quality, and comfort that despite its price it's still a strong value.

Of course, with a headphone like this and a name like Sennheiser, it's the sound you're really after. With stand-alone loudspeakers, the goal is generally to provide balanced sound across as much of the audible sound spectrum as possible (roughly 20 to 20,000 Hz). High-frequency reproduction is easier than low, simply because low-frequency reproduction requires a speaker to move so much air. Speakers capable of rendering deep bass usually use large speaker cones--8 inches or more in diameter--to help move the necessary volume of air.

Headphones, of course, are restricted in the sizes of the drivers they can use. Being so much closer to your ears, the amount of air they need to move to convey bass frequencies is much smaller, but still a challenge for what are basically tiny speaker cones. And anyone who's listened to a lot of headphones can tell you, there's almost always a tradeoff in what a headphone driver is capable of. Some produce balanced overall sound with little in the way of bass; others aim for bass at the expense of natural-sounding midrange and coloration-free treble.

The Sennheiser HD600, we're here to tell you, manages--through its extremely high-grade parts and exquisite engineering--to bring home truly full-range sound with remarkable timbral balance. Rich, deep, effortless bass grounds the listening experience while the headphone's airy midrange and treble help render everything from acoustic bass to soprano saxophone and electric guitars with a haunting degree of realism.

The HD600 doesn't offer the lush midrange favored by tube-amplifier enthusiasts--tube fans may find the headphone somewhat bright and maybe even strident in tone. But the rest of us will revel in the expanse of crystalline detail and snare-snappy dynamics.

The exceptionally natural quality of the HD600's overall sound bears reiteration, since so many headphones with "fat" or even "slamming" bass response deliver the low-end goods with a degree of emphasis that, while pleasing to bass aficionados, grossly distorts the frequency balance, limiting the range of music and recordings that will sound good on those headphones.

How does Sennheiser do it? Through computer-optimized magnets--critical to driver operation--that minimize harmonic and intermodulation distortion, granting the HD600 its uncanny clarity and spaciousness. Furthermore, the headphone's advanced diaphragm design eliminates standing waves in the diaphragm material, preventing unwanted emphasis at otherwise resonant frequencies.

As good as this headphone is, however, we don't recommend it to those seeking a stellar headphone for portable use. While this unit is capable of amazing sound, its best performance requires more amplifier power than most portable devices can muster. The HD600 owes its strength in part to its large drivers, which just can't be moved as easily as those in smaller headphones.

Furthermore, the HD600's open-ear design means that sounds pass easily into and out of these headphones, which would in all likelihood prove irritating to you and to those around you in libraries, on buses, and even at the office. These are only our suggestions, however; the fact is your MP3s will probably never sound better than when you're playing them over this headset.

We'll just leave you with one last suggestion, then: if you're after the best-sounding, most comfortable audiophile headphones you can buy at anything resembling a real-world price, look no further than Sennheiser's HD600. --Michael Mikesell

Outstanding, if pricey, headphones
Most people have probably never thought of spending ... for a pair of headphones, but if you care about the music you listen to, this is actually quite a bargain. I considered both the Sennheiser HD600 and the nearly identical but less expensive HD580 headphones; I chose the HD580 which gives nearly all the quality at about half the price, but sadly those have been discontinued. Nevertheless, I do agree that the HD600 is probably the best dynamic headphones available today; listening to music, especially well-recorded acoustic music like jazz and classical is an experience you will never be able to approach using anything near the same amount of money, certainly not loudspeakers in this price range. Although there have been comments... that these headpones may be a touch bright, I feel that they are actually simply more accurate, without the boominess in the bass or extra "presence" in the midrange which are designed into many other headphones. Also, these are open-air headphones; the open-air design has the advantages of being more comfortable (your ears don't get hot) and offering a cleaner and, well, more OPEN sound. The disadvantage is that they provide next to no isolation from external noise, so forget about these if you want headphones for the commuter train. If you turn up the volume people in your immediate surroundings can hear the music, but unless you're listening to rock and roll at ear-bleeding volumes in bed while your significant other is trying to sleep, this shouldn't be a problem. All in all, a great investment in musical enjoyment.

You will start smiling!
I just bought the Sennheiser HD600's and was able to compare it directly with the Sennheiser HD580's and an old pair of Sony MDR-V6's.

One of the best CDs to use in listening is the Buena Vista Social Club CD. Ry Cooder, et al. did an excellent job miking and mastering, capturing the natural sounds of voices and instruments.

The Sennheiser HD580s were rated as a "B" component by Stereophile Magazine, and the HD600s receive their top "A" rating. The HD580s (discontinued) sounded wonderful -- very spacious and detailed; however, the higher frequencies seemed a bit too high, making cymbals sound a bit harsh. Since the HD580s use basically the same components as the HD600s, I was expecting the two headphones to sound very similar. But when I put on the HD600s, I was floored. The headphones seemed to disappear and I was listening to the instruments directly. The HD600s had all of the spacial qualities of the HD580, but the sound was warmer, closer, and more realistic. For example, the piano on Track 4: Pueblo Nuevo sounded pretty darned good on the HD580s, but it seemed like I was really in the same room as Ruben Gonzales when I listened with the HD600s. The HD600's presentation of the piano timber was spot on. Track 12: Murmullo was incredible -- you can hear every detail, every nuance, every whisper, of Ibrahim Ferrer's voice. Once in a great moon, a new product will bring a smile to my face...the HD600s did that.

After listening to the Sennheisers, I wanted to throw away the Sonys. You will also be tempted to throw out all of your CDs that aren't recorded and mastered well, because you'll hear all of the imperfections. If you don't have enough money for the HD600s, then do a little overtime to earn the bucks...the delayed gratification will be worth it, guaranteed.

WOW!!!! THIS THING IS AWESOME!!
Wow! I just got my HD600 and I cant say enough how pleased I am. This thing is AWESOME!! Word just cannot describe enough how great this headphone. Please, do yourself a favor and get this thing immediately. I GUARANTEE YOU WILL NOT BE DISAPPOINTED!!!!!!

Sennheiser HD600
I bought these Headphones just yesterday, have been using them for Multiplayer gaming and Music on my PC. The quality of sound is outstanding, highly recommend these.

The price leaves a bit of a hole in your pocket though!

Creme de la Creme of Headphones
I purcased these and was simply blown away with the outstanding detail, exeptionally comfort, and surprising bass quality.
I hooked these up, and cranked up some "Rush" and when normal headphones (and speakers) fizzle out on too much sound, these heaphones maintained every note while the music played at high volumes.
These headphones make you feel like you are standing next to the recording artists. I am still astounded by the amazing accuacy and quality these headphones produce. A++!!

I give these 11 out of 10. ... Read more

Great headphones except for a design flaw.
The headset is nice except for the fact that they broke after 2-3 weeks of use. I can only hear out of the left side and the microphone no longer works. I guess I get to find out how good sennheiser is for support.. the main construction is quite good (hard to break them) except for the tiny little cable that comes in on the left side. I suspect that my headset failure is related to the small cable. Other than the weak/tiny cable this is a really good headset.
The microphone and audio quality is quite good. It is more comfortable than other behind the head headphones I have worn. I had many great gaming sessions with this headset. People heard me clearly and I could hear everything clearly not to mention they remained comfortable for many hours of play.
Hopefully my next pair will last longer.

Poor quality
Headphones broke two weeks after I bought them. Can only hear out of one side of them, only plus side to them is that the microphone hasn't broken yet. ... Read more

This is undoubtedly the battery for you
It's pretty hard to write a review of a battery; it either works or it doesn't. This one does. It also fits the unit for which it was intended. So that's two points right there.

If you have a set of Senns, and the batteries that come with it aren't enough to keep you going (I actually find that they last closer to five hours than the four advertised), then this is the product for you. You might even want a recharging unit too, since they take at least fourteen hours to recharge, and the headset stand only holds two batteries. The spare battery can be crucial if you're like me, and often use the headset all day at work! Go for it!

Always have an extra battery on hand...

Don't waste your time.
I guess Sennheiser assumed that only DJs would use these phones, in bass-heavy dance club environments, because they completely neglected the low-end response from the phones themselves. The mid-range (vocals, etc) sounds excellent, the highs are a tad bright, and the bass response is non-existent. If you listen to rock, dance, hip-hop (basically, any type of music with pronounced bass), you will hate these phones.
On the plus side, I guess they are comfortable. Sennheiser should take the headband from these and use it to replace the horrible headband on the 280 Pros, which sound great but are horribly uncomfortable.

Sound alright but cheap processing
These headphones have a nice sound - very clear. But they start to give up when you turn your stereo up a lot and the bass starts to crackle. Further they can't not be used with a little device like a CD player - there has to be something stronger to drive these headphones. I've tested them with my personal computer and my home stereo and they worked nicely until you turn up the sound to a certain level.

I expected a little bit more of these headphones concerning their processing - they look like the a lot cheaper Sony MDR-V300.
But, despite the cheap look, they are very solid and stable. And they have a weired feature with one of the earcups - you can turn it 90 degrees but I have not found an advantage yet.

Overall, I don't find a lot of use for them in my daily life (with CD player which is ont strong enough to drive it) AND my home recording experiments. If you use headphones like me and you want to have good ones, I'd recommend Sony MDR V700DJ (yes, I have had the Sennheiser HD280 which are great but not as comfortable if you want to use them in your daily life). ...

Professional Audiophile Quality
These new model Sennheiser headphones HD-515 sound have a sound that has much depth and richness. There are no others in their price range that sound as good. These are really very comfortable, lightweight, and reasonably priced. They are easily adjustable to comfortably fit any type of head!. The quality of the HD-515 construction is an obvious upgrade when compared to many less expensive models of headphones. The headband pad on the HD-515 is a comfy foam padded cover. At 9oz the Sennheiser HD-515 headphones are fairly light-weight. The ear paddings are comfortably large and are made of soft velour. Long use comfort of the HD-515 is very high. Thanks to the new ultra-efficient drivers it doesn't take much amp power to drive these Headphones to give you a full loud sound. So they should work well with portable audio devices. They are perfect for the high demands of audiophiles who listen to CD,SACD,DVD Audio. Sennheiser is right to call the HD-515 audiophile quality. These headphones are also the first to incorporate a new feature that Sennheiser calls Eargonomic Acoustic Refinement system. Which slightly angles the acoustic baffle within each ear cup to assure that sound projects precisely parallel to the ear. This improved acoustic coupling is meant to help optimize the ergonomic participation of ears in the listening process. The bass is very clear and not muddy like some headphones in this price range. But it is not really deep sounding bass. Treble is sharp, crisp and clean,not too forward. For best results I really recommend giving any headphones a break in period of a minmum of 40 hours. After this break in period you will fully appreciate these headphones outstanding sound quality.

Horrible
These are horrible. I wouldn't recommend them to anybody. A lot of people I know don't even fit into these. I have a friend name Carly, she has a very awkward-shaped head. Her head won't fit into these and when she puts them on they just fall off her head.

Nothing but the best!!!!
I just got these a couple days ago. Wo!!!!!!!!! This was good stuff. Let me tell U. The sound is incredible like your really at a concert. I used them for this one classical song and I could have sworn I heard people pressing down the valves of their instruments. These are great for the price!

Great with Home Stereo, Not So Great with portable Audio
After much research and deliberation I decided to pick up a pair of the HD 515's through target.com Put simply, these headphones are extremely comfortable, stylish, and produce a phenomenal sound with rich treble and bass when connected to either a home stereo or computer system. I originally bought them thinking they would be driven and sound adequate with my 15gig ipod, however, the ipod doesn't seem to have enough power to fully exploit the headphones. Again, great for home stereo, not so great for portable audio...*I would recommend the sennheiser pmx60's* however, as a great headphone for portable audio!

Very good headphones
These a one of the best headphones for the price. They have great bass reponse and low distortion at high volumes. I use them mostly to listen to movies not to disturb others and they are almost as good as my surround sound system. I am very pleased with HD-515s for the price and the comfort I could wear them all day even with glasses on. And a plus is you can replace parts if you need to. ... Read more

Amazon.com Review

Sennheiser's HD570 headphone replaces the discontinued HD545 model. Like the model it replaces, the 570 uses an open-ear design that lets you clearly hear environmental sounds but also allows other listeners in the room to hear the music being played. The 570's earpieces also have a sharply pointed bottom, designed to more closely encircle the ear--those with particularly large ears may even find these snug. However, like all Sennheiser headsets, the 570s are extremely comfortable to wear for long periods of time, assuming the fit is good.

And, like almost all Sennheiser headphones, the HD570s have a rich, seductive midrange and deep, authoritative bass response. Where this set differs from most of the line is in its top end. The 570's high frequencies are more pronounced than the usual Sennheiser sound, as typified by the glorious HD600 and now-obsolete HD580. If you find the sound of those headsets on the dark (high-frequency restricted) and unexciting side of accurate, you'll likely be delighted with the tonal balance of the 570. On the other hand, if you find those models just right, you'll hear the 570 as bright, possibly even extremely bright (with accentuated treble response).

Of course, this also depends upon the source components you listen to. Cassettes and underpowered portable CD players might actually benefit from the 570's high-frequency boost, whereas most receivers or separate headphone amplifiers don't need it. Because the HD570 wants a fairly substantial signal to sound its best, however, it should not be used with most portable players. Dedicated amplifiers produce the best sound.

This is a comfortable headset with a different tonal balance from most Sennheisers. We suggest careful consideration (abetted, perhaps, by a 30-day return policy) before committing to living with the HD570. However, if this is the sound you're looking for, the HD-570 is rugged and extremely well constructed. You'll get a lifetime of use out of them. --L.V. Phillips

Pros:

• Lightweight design and padded headband make them comfortable forhours of listening
• Low-distortion Duofol diaphragms provide exceptional detail andclarity
• Single-sided cable makes it easier to move around while wearingheadphones

Cons:

• 64-ohm impedance level makes headphones difficult for most portableplayers to drive; works best with dedicated headphone amplifier
• Somewhat bright (trebly) tonal balance may strike some listeners astoo much of a good thing

Features

• Over-ear, open-back stereo headphone
• Single-sided, 10-foot OFC (oxygen-free copper) cable
• Proprietary Duofol membrane reduces diaphragm distortion at edges
• 18 to 22,000 Hz frequency response
• Designed for comfortable long-term wear

Very impressed...
Another Sony switchover.... gotta say, these are some really great headphones... what everyone says is true - you do hear things you've never heard before, even in music you are familiar with. There isn't too much I can say bad about these things - the bass isn't as deep as I would like it to be (using an EQ fixes that, and these headphones can definately handle deep bass without a sweat, but they dont have that to start with), but the audio is exceptionally clear among the whole spectrum, especially on highs and mids, and distortion really isn't a problem. At first, the sound seems to crackle a bit, but this was in part due to some of the lower quality stuff I was listening to, and in part that these were new. After letting them play overnight and wear in, I am hearing much less - this is just my second day of using them, and every hour the noise decreases more. They seem to sound better as I wear them in more with my types of music - rock, metal and trance - so those who say they dont work well with these genres are often those who have tested them right away and not wait a few days before making a consensus. Also, these things - rated at 64ohms impedence - could hardly be heard on my portable player... so for portable use, consider your device before you buy these headphones. What are the plusses? Well, everything but that which I have already stated... they are very lightweight and sometimes I forget I am wearing them, the detachable cord is handy (since I have already pulled it out 3 times, which wouldn't have really been good on the cord if it wasn't detachable), and the quality is excellent... plus, if you look around, you can get them (comparably) pretty cheap :) I dont know how I avoided good headphones for so long!! :)

Great Headphones
These headphones are so, so comfortable! It's unbelievable. I know the top-of-the-line ones are probably more so, but they darn well better be if they cost upwards of three hundred dollars! Others say that these headphones are only good if you listen to symphony. I listen to techno, rock, jazz, hip hop, blues, and symphony. These headphones perform well above average in all types of music. It is true that they sound especially wonderful when listening to symphony, but that just makes then sound RELATIVELY bad with other types of music. If you're a symphony lover, a pair of headphones won't make you like hip hop any more than you already did. The fact of the matter is that the bass, midbass, midrange, upper, and treble, (as well as any other range) are excellent. Personally, I am a Bass head. You know, those guys that drive down the street with 1000+ watt stereos in their cars, registering multiple points on the richter scale as they pass. These heaphones are satisfying to me because I can crank up the bass on the EQ and they'll take whatever you give them. Normally, they are very well balanced, and the signal can be tailored to anyone's tastes.

Upshot: for the price, these headphones more than earn their keep. If I had a little more money to spend, I would definately come back to this company for my next pair of 'phones. The HD600's are calling out to me!

Yep, the tonal balance is different, and the volume is lower
I have two HD-545 headphones and have gotten quite addicted to their lovely, rich, and incredibly clear sound. They were getting a bit worn however, and I have already replaced the cords on both of them. So I decided to try this headphone, mainly because the Amazon.com review said that the HD-570 was supposed to replace the HD-545.

Well, the HD-570 definitely has a different sound compared to the HD-545's. The Sennheiser website shows a frequency response chart for this headphone that describes it best, basically a dip in the midrange frequencies. And that's what I hear - the highs are quite sharp, the lows are definitely there, but the middle frequencies just seem to be dulled. And so the sound that comes out of these headphones lacks the rich fullness and ringing clarity of the HD-545's. With the highs and lows both registering fully, the sound can be both more shrill and booming at the same time, depending what's in the music that you are playing. "Muffled" isn't quite the right word, since the highs still come through, but yes, these headphones sound muffled.

Anyway, if you listen to the HD-570 exclusively, you can get used to the sound, it's not as bad as some of the reviews would make it. It's only when I do a direct comparison with the HD-545's that I kind of regret getting these headphones. Definitely, I like the HD-545's sound better, but then, I've been listening to them exclusively for about ten years or so.

(...).

Finally, there is a difference in the volume of the HD-570. It's not horrible, but on one computer, I have to max out the volume just to get it loud enough.

Not Private Enough
First - the cons. Although the specifications do state "open dynamic", they're more open than i thought. You will have no privacy , and may upset commuters trying to catch 40 winks if you turn up the volume. If you want loud, ferocious headphones, look elsewhere. These have a mellow full-range, full-body sound, that can never be called "ferocious".

Pros - Excellent bass, mid-range and treble response...mid-range being the weakest. For those complaining of a weak bass, two points to think over -
1) Breaking them in makes them sound better over-all.
2) The 64 Ohm impedance means they are basically intended for receiver/amplifier/Hi-Fi use, and not really for small MP3/MD/Walkman players.

These really sound amazing when driven with sufficient power. Repeat - not the best with portable audio, although that is what i use it for. I was sold on the comfort and lightweight-inspite-of-large-size factors.

Despite the by-line, these are not Over-Ear (Supra-Aural, in the lingo) in design. They are in fact Around-The-Ear or Circum-Aural which is why I bought them. In theory (and in practice) they do not touch any part of the ear, greatly contributing to the comfort quotient of the product.

Don't Waste Your Money...Seriously. Bad.
These headphones are incredibly horrible. I would give them zero stars if I could. I would maybe pay $10.99 for them... if I was short on cash and I wanted really crappy headphones. There is absolutely ZERO bass (although there's buttloads of treble! [I can't even hear the bass guitar in most all of my cd's]). They sound like everything is being filtered through a tin can. If you listen to rock music or you need accurate sound reproduction, don't even consider buying these. The only thing I would ever use these for is MAYBE listening to talk radio (but i never do that anyway).
