SennheiserHD 600 - Audiophile Hi-Res Open Back Dynamic Headphone

My road to the Sennheiser HD 600's has been a little long and filled with some interesting twists and turns that have, or so I hope, led me to a better understanding of what are a great set of headphones. Naturally it is very typical to wish to compare these to other headphones. After all, isn't that how we so often make purchasing decisions? We try differing products until we find the one which works best/right for our needs. So my review is going to work on two fronts: a review of the product itself, and a review against some competitors I have acquired in the last year in my quest to find headphones that are right for me. And hopefully for you.Regarding the HD600's themselves I have mostly nothing but excellent news to report. Personally, I like the way they look. The mottled black and blue coloring is different, but not garish in any way. The large and deep oval ear cups are precisely what one wants for an over-the-ear design. At 6'4" I'm certainly sporting a larger head than the average male and fortunately for me my entire ears fit comfortably inside the ear cups. My ears do not touch the protective cloth over the drivers, but the outer edge of my ear does touch at places around the inside of the ear cup. This is a minor annoyance and goes unnoticed some of the time. Those of you more average of height and head size will likely never have this issue. The ear cups themselves are very comfortable, seal well to my head and do not get hot even after a good number of hours of use. This also means the head clamping force is perfect for me; I never feel like my head is being squeezed. Everything about the headphones seems to indicate they are well-made, but I cannot help but feel the plastic seems a bit thin. Maybe cheap even. They do not creak and nothing flexes, but it's the only part which lets me down at all about the headphones.The included box, while awesome for storage, is clearly not oriented for travel. But I would argue these aren't portable headphones meant for the on-the-go user. They do not fold up. The ear cups do not turn to lay flat. And considering the amplification needed to properly drive these, using a typical portable music player (your cell phone, iPod, etc.) isn't ideal anyway.Now for what I consider to be the more important part of how I came to select the HD600: research and listening. Let's first be clear about something... audio equipment is not unlike some other equipment markets in that you often spend exponentially more money for an item just to gain minor, incremental increases in some important criteria. To you speaker X sounds better than speaker Y, all other things being equal. It's likely speaker X costs more. Most of the time it will cost more, but not all of the time. But how much more does it cost and how much more quality of sound are you receiving for that additional cost? It's almost always a matter of diminishing returns... loads more money for a bit firmer bass or slightly clearer treble. But this is the nirvana for which we seek in audio equipment.Over the last year I purchased two other sets of headphones: Grado 80e and Sennheiser Momentum. Clearly the Grado's at $100 are the least expensive with the Momentum jumping up markedly to $299, while the more recently acquired Sennheiser HD600 hit the $400 mark. Comparing my first two purchases, the 80e's and Momentum's, the differences were pretty straight-forwarded. To me the Grado's sounded brighter with good bass and sligthly harsh mids ("smeared" is the word which came to mind as I compared them in listening tests at home). The Mometum's sounded more laid back (not as bright) with great bass (that could be a bit smeared itself in the upper bass) and definitely superior mids (thinking men's voices here - became painfully obvious will using a live track from Morrissey between the two headphones). And so it was I came to find myself using each pair for different purposes.The Grado 80e's became my preferred can for classical music (a genre into which I am becoming more deeply involved of late) as I felt, for my personal preferences, the brighter qualities enhanced the instruments typical of classical music, while the bass was more than sufficient. But when I wanted to rock (or alternative as is more often the case) I broke out the Momentum's. The accentuated, but not overblown bass, was quite welcome and I noticed less the laid back nature of the treble, especially as I used them more and more.But with the also recent purchase of some better home audio equipment (Marantz CD6005 CD player and a SoundEngine D1 DAC/Headphone amp for my computer - listening to ALAC encoded tracks) I found myself thinking both the Momentum and 80e were somehow lacking. That I wasn't getting everything I could from my music via this better equipment.From all the research I had done previously I elected to spend the money and purchase the HD600. I don't think I have found a single bad review out there in the Internet sphere. A few have thought them a little warm or laid back. But most every review hits upon how, and especially for the money, the HD600s hit all the right notes (sorry). Having had them burned in for 30-hours the listening tests began. I had considered this purchase principally for classical music. I really didn't think I'd get more from them for rock/alternative than I was already getting from the Momentums and so it was the classical CDs came out and I plugged into the CD player. I also plugged in the Grados to the Marantz A/V receiver, direct mode engaged. Adjusting for volume as best I could (this is hardly scientific) I played a handful of very familiar tracks from very familiar CDs; swapping back and forth between the HD600s and Grado 80e.It too almost no time to hear the difference. I'll concede that it's sometimes difficult to put into words the differences heard, but I'll try. The first thing I noticed were the violins. When a number of them are playing notes together the Grado's sounded smeared compared to the HD600s. Not unlike a poorly created JPEG from a digital point-n-shoot versus a well-made JPEG from an original RAW processed via Adobe Lightroom. Details are are lost in the former, but the latter does a far superior job of keeping the detail even in the process of losing information. The HD600 left me feeling like I was actually sitting there in the room with the musicians. I'm not referring to placement of the instruments (the HD600 do a good job, but I've read reviews for other cans that do better), but simply how clear, precise, concise and live-sounding are the violins. Actually, it was true of all the stringed instruments. The resonance of the strings... their very clear nature... was a welcome and astonishing difference.Granted, the Grado's are one-quarter the cost and I shouldn't be surprised the HD600's sounded better. Markedly better. And I didn't have to listen long or hard to notice the differences. They are obvious; not subtle. That said, I can't say I was every displeased with the Grado's. It was only in comparison to the HD600's that it became possible to hear and understand the Grado's limitations.And like the stringed instruments, voices also became sharper, clearer, more focused. I had found what I was looking for regarding my classical music interests: a pair of headphones that while generally neutral (which some would consider to be 'flat' and flat has, I think, a negative connotation), are not at all boring or flat. I feel the music is more alive than ever in comparison to the Grado's.So... I also broke out some rock and alternative music (the recently remastered Led Zeppelin discs, some Nine Inch Nails and Pet Shop Boys) to see what the HD600's could do. Here I feared the Momentum would just kick butt thanks to the fuller bass, but I must say the HD600's continued to impress. All the good things they brought to mid and higher frequencies (clarity, precision) were still present, but, surprisingly, the bass was rock solid as well. I may hate myself for saying it, but I think the bass was a bit better. The upper-bass bloat in the Momentum's doesn't appear on the HD600's, which tends to make the lower-bass stand out more because they aren't overwhelmed by the enhanced upper-bass. I'd still say the Momentum's have more punch and who doesn't like that when listening to rock or alternative, but I could find myself readily using the HD600's just as often for The Smiths, The Cure, Skinny Puppy, etc. as I would the Momentum's.And here I think I have found a most excellent trio of headphones. Finding one perfect pair of headphones for all needs and opportunities is probably impossible. But I think I have accidentally stumbled upon a most excellent hat trick of cans that meet my various needs. I like to listen to music when I'm on the go; I have needs for portability. And while not truly the most portable of headphones, the Grado's for classical (and still quite reasonable for rock and alternative) and the Momentum's for rock and alternative (I confess I don't like them as much for classical as I do the Grado's for rock and alternative), AND the HD600's for more critical, at-home listening with audio equipment that has enough amplifier ooomph to properly push them.Add my name and voice to the long list of of folks who think, dollar for dollar, the Sennheiser HD600 are the best value in headphones out there.

It's easy to forget that, next year, the HD 600 will turn 20 years old. Admittedly, audio transducers have a funny way of sticking around longer than just about any other piece of electronics equipment. A line of speakers will, usually, be in production for at least several years. Even when they've been replaced, they usually aren't even close to obsolete, because even mid-fi has gotten pretty far into diminishing returns. But, even in this alternate timeline of audiophile-dom (others might call it an alternate reality, an insane asylum...) the HD 600s are freakin ancient. I can only think of a few other cans with this kind of longevity:The Sony MDR-V6; so old that it still has "for DIGITAL" emblazoned on the side. A quick trip through audio theory will reveal that this is meaningless, but in 1985 it sounded really cool.The Beyerdynamic DT770/880/990; so old that they still have shag carpet earpads.Various Grados; so old that it's too late for anybody to admit they sound like trash. Instead, they just mumble something about "sparkle" and then go buy something else.And yet, 20 years later, the HD600 is still the headphone that, within headphone circles, everybody talks about and everybody has heard. There's a reason for that: it's not just really good. Purely on the strength of its sound, it stands out as excellent. When price is considered? It might just be the best headphone in the world.THE SOUND:Inevitably, whenever anyone tries to talk about the HD600 or the HD650, someone brings up the "Sennheiser Veil." This so-called veil was a kind of muffling of the sound, and the people who complain about it would have you believe that the HD6XX sounds like Apple Earpods.I cannot state emphatically enough how much the veil does not exist. It is either a product of the imagination of people who wish the AKG K701 was a bit brighter, or the result of people trying to plug the HD6XX straight into an inadequate source, i.e. most phones, MP3 players, iPods, laptops, etc. They need an amp. More on that later. At any rate, these headphones are as veiled as Eva Green in The Dreamers. You. Will. See. erm, Hear. Everything.That's both a blessing and a curse. Lesser headphones - even my Sony MDR-V6s, for instance - can mask the flaws in a bad recording. All of those 128kbps MP3s you've pirated because you're a bad person? They're gonna sound awful. If your father-in-law-to-be hands sends you some recordings of his garage band, grab however awful a set of backup cans you need for it to sound good. Because these will tell you the truth. Yet, to a good recording, they are shockingly flattering. If you put garbage in, you'll get garbage out. Give it something good, though, and you'll get magic. I've listened to just about my entire music library with these, and there are a few recordings in particular that really demonstrate how well these shine:-In the Air Tonight (Phil Collins, Face Value, 1981): On a decent-to-good set of headphones, this song sounds ominous; it sounds cool. Whatever. On the HD600s, it's a religious experience. Sounds swirl around your head. The crescendos and diminuendos blow you away. The vocals sound perfect. Incredible.-In Your Eyes (Peter Gabriel, So, 1986): The entire album is fabulous. Listen to it over and over again. But there's a reason this song is singled out. It's a sibilance nightmare. On my MDR-V6s, it's unlistenable above a moderate volume. Enter the HD600s: there's no hiding how much sibilance there is, but they handle it as gracefully as possible.Enough ink has been spilled over how these handle classical and jazz (spoiler: fabulously), and their vocal presentation in particular is spot-on.THE STUFF YOU'LL NEED:To get all of this brilliant sound, you're going to need a few things. First and foremost is an amp. This can get crazy pretty quick, so first let's draw a distinction: solid state vs tubes. The HD600 has a high enough impedance to really get along with OTL amps (ie, most headphone tube amps). This will color the sound somewhat, get hot, be unreliable, need to warm up, etc. If you want to go down this road, you can. There's also a lot of really expensive solid state amps.Or, you could just get a Schiit Magni or a JDS Objective2, both of which sound... well... about perfect.Next, you'll need to think about a DAC. Now, a lot of people just assume they'll need one. That may not be the case. If you have a Retina Macbook Pro, for instance, skip it. You'll never hear the difference between it and whatever you get for 150 bucks. Same deal if you're plugging a (good) CD player or receiver or whatever straight into the amp. If your source is something else, like a midrange PC, you'll need to evaluate this yourself. Unfortunately, I can't help you with that.If you decide you need a DAC, there are a lot of expensive options out there.Or, you could just get a Schiit Modi or a JDS ODAC, both of which sound... well... about perfect.(Side lesson: The internet audiophile community fights back and forth all the time about whether the O2/ODAC or the Magni/Modi is the better setup. Realistically, their performance is nearly identical. Buy whichever you think looks better.)(Another side lesson: You seriously probably don't need to spend a ton of money on DACs and amps. The O2/ODAC was designed by some wacky internet crusader who wanted to prove that the performance of the Benchmark DAC2 and HPA2 could be achieved without spending thousands of dollars. From an engineering perspective, this is obviously possible. If you look into this further, you will still find people who insist that the O2/ODAC doesn't sound as good as significantly more expensive gear. Just remember that these are audiophile crazies, who think they need 192kHz recordings because Nyquist-Shannon doesn't apply to special snowflakes. The two most important things in any digital-to-analog system are the input file and the transducer.)Finally, you're going to need good recordings. iTunes is sufficient. Vinyl is pretty good (repeat after me: vinyl does not sound better than CD, it is objectively worse, a record will only sound great 25 times, and will be the equal of the CD never). CD is your best bet, particularly those mastered before the "loudness wars" started up in the late 1990s. However, the world isn't perfect; fear not, the Senns still sound good with stuff that has a compressed dynamic range (within reason). Anything beyond the Redbook CD standard is simply a ploy to get you to spend more money for things you can't hear, and that your dog can't either.SOME REALITIES:The way that the Senns achieve all this great sound is by being "open-back" headphones. This means that, on the side of the driver opposite your ear, there's just some mesh to protect it from damage. This means that you can't really use these outside a quiet environment, because you'll hear everything around you. It also means that you probably won't want to listen to them in public, because it's really difficult to look cool when everybody knows you're blasting the Bangles.Also, they're ugly as sin. But they aren't leaving your house, so who cares?A WORD ABOUT THE HD650:Released several years after the HD600, the HD650 at first glance looks like an upgrade. That... depends. The HD650 is darker and smoother at the expense of detail. That's all. I prefer its sound signature. But, it usually costs between 75 and 150 dollars more than the HD600, and so it wasn't worth it for me. It probably isn't worth it for you, either.So, yeah. These headphones sound just about dead neutral, wonderfully crisp, and yet smooth enough that you can listen at high volumes without fatigue. They can usually be had for less than 300 dollars. And for the price, they have no equal. Now we just have to hope that someday the HD800S can be such an easy decision to make.

just wow.yeah they clamp a bit when new and do need a break in. but then omg everything sounds amazing. i just thought all headphones are the same.......nope. even while gaiming they are amaizng. currently playing final fantasy 7 rebirth and the soundtrack and game sound like jesus when hes singing chris stapleton lol. buy 10/10 would recommend.

Bought these in October of 2014, over 10 years ago. I returned here to see the price has dropped by $50 as I had paid $399. These are by far the best phones I've ever used. I'm a professional musician and I wear these almost daily. The only sign of wear is the small thin screen that covers the inner speakers. These headphones (HD600) have fallen off the desk onto a wood floor several times, the cord has been stepped on and rolled over by my office chair yet there's no signs of wear not even the felt which covers the ears. Highly recommended.
