What our customer's say!

"Great cans for the money", These are great headphones - neutral, smooth and easy on the ears for nearly all types of music. I've got a few sets of cans including the Audio Technica A900, Shure E2C and Future Sonics Atrio M8's. The new Senn's are easily my favorite, particularly after breaking in for a few days. Typical use is with a Zune 30gb, powered by a Little Dot MK1 portable amplifier. The amp really helps drive the Senn's well although the Zune is capable of decent sound on it's own if you don't have any amplification.

The Senn's are very comfortable for extended periods of listening, my longest is about 4 hours at this point. They fit nicely over my ears without any trouble although do slightly pinch my head. I'm not a small guy so this may not be a problem for everyone but be aware they do fit pretty snug compared with the Audio Technica A900's at least. No problems with sweating or getting warm, the earpads are cloth, which I suspect helps a great deal.

Build quality seems fine, although the cable seems pretty flimsy (it can be replaced but get your wallet ready) and the marbled plastic look isn't necessarily my favorite. The box it comes in is very nice, and Amazon did a great job packing in a very large box with plenty of packing material.

"Fantastic headphones", I could go on and on about these phones, the umpteen reviews you read on this site indicate what you already suspect, these are phenomenal quality for the price. They are comfortable, sound fantastic, and have stood up to abuse by me and my two teen age sons. I got them on a whim, wanted some nice headphones to listen to classical and jazz music without disturbing my family. They quickly disappeared into my two teenaged son's bedrooms who listen to a variety of music, rock, jazz, pop, choral, everytihng. You can spend a lot more and not get any better. Just buy them and enjoy, you won't be disappointed. they will produce anything you want from the deepest 32 contrabombard, jaco pastorius, the Flecktones, the Stones, the Guarneri quartet, to Joshua Bell and Izthak Perlman. These are the best. Not to be missed!!!

"Good set for mixing and portable studios.", There have been so many reviews here I almost didnt write one but with the lack of reviews by producers I decided to add one more to the list.

If you're producing audio like myself you already know theres no replacement for a good set of monitors. That said there's a few reasons you may be mixing through a set of cans.
My reasons are that my studio is sometimes mobile and that I'm often mixing in my apartment (I've found that boxers and a t-shirt are a superior choice for studio apparel).
I'm running an Mbox2 with Pro-Tools 7 (sometimes switch to Nuendo... don't hate me... hush now Abelton users).
I also use these with my Ivory Keys VST and it sounds pretty nice, I think they add a bit of warmth when compared to a set of Mackies, could be the spatial difference, but I actually like it better through the Senns, a bit more personal I guess.

That said, I feel pretty happy with the sound from these cans.
I've been using them for almost a year now, extensively.
They're a bit lacking in the low-ends when I push them, but when you pair them up with an analyzer you can usually compensate pretty nicely with a combo of visual and audio reference.

They are open-ear, so dont expect your vocalists to be using them in the sound booth or you'll be recording the sound coming from the headphones along with the vox. For the producer, the only real place for these is in the mix down if you're trying to be quiet... or your one of those weirdos who uses cans for some bizarre voodoo mixing ritual.(I've heard of these guys but never met one)

They are definitely more comfortable than some of the other headsets I've tried, Grado's being the least comfortable, Sony's aren't bad.
Sometimes I seem to put them on wrong and my ears start hurting pretty quickly but if I slide them around on my head a bit so my ears are good and centered I can wear them for a few hours before I need to take em off.

I think the most important thing to note here is my experience with Sennheisers customer service.
Recently I snapped the headset in half, dunno if it was from cheap plastic construction or just lots of use. Regardless I contacted Senn and asked what I needed to do, assuming I'd have to send them in and wait a week to get them fixed. Instead Senn offered to just send me a new headband and I could replace it myself.
Because of the modular construction of these cans that will be pretty easy to do and lets me keep using them while I wait for my replacement.
Needless to say, that made me pretty happy.
The cords firmly snap in and out of the cans via 2 pronged plugs, nice for those who accidentaly step on the cord while they stand up.

On a consumer level note, if you are listening to MP3's or any compressed audio format in a portable device... or any device for that matter, dont buy these, you're wasting your money.
I'm not insulting you, I'm being serious.
There are cheaper alternatives for compressed audio.

If you like your music and can't blast your speakers for some reason or the other, then I'd say these are a pretty nice set. Not the best for sound but close enough that the price and comfort make up for the slight difference you may hear in a set of (very uncomfortable) Grado's.

For those of you who are worried about reproducing the "original sound" of a recording, you need to laugh at yourself for a minute and realize that we process those sounds pretty thoroughly before we even bounce them to a track. Compressors, EQ's, Verbs, etc., sometimes before the signal even hits the sound card it's gone through a pre-amp. Aside from that the difference between audio still in the DAW and a bounced track is pretty dramatic. You're just not going to hear what we hear in the studio. Go with what you like.
Some like it crispy, some like it warm.
If you can listen to your favorite track through the headphones before you decide to buy them, do that.
Leave em on your head for a while see how they fit.

I recommend trying them out if your searching for a set.
They work nicely for my purposes.

"Exactly what I expected", I've been wanting to buy a HD600 for many years because it seemed to be the benchmark for a lot of professional studio engineers and reviewers, not to mention budding audiophiles. But I hesitated because it's pretty expensive in Australia (A$600-700) and wasn't sure whether I wanted an Open headphone. Until recently I only had Closed ones including Sennheiser HD280pro. But I bought Koss KSC75 and Alessandro MS-1 (a tweaked Grado SR80) open headphones and liked the sound. Given the recent fall of the US dollar, I decided to purchase HD600 from amazon - even after a hefty shipping charge of US$54, it still only cost me US$349 (about A$385).

I burned it in for about 200 hours using a variety of source materials including a couple of audio test CDs. I mostly listen to my music collection (re-ripped in either ALC lossless or AAC 256kbps) in my iPod Classic 80G via line-out to my Minibox-E headphone amp (which is a fantastic little amp I got from Head Direct for US$159). (It's not a good idea to connect your amp to the iPod's earphone output. Buy a line-out connector.)

The HD600 is beautifully built and wonderful to look at. Its clamping force is a bit too strong initially but it gets better with use. It's now one of the most comfortable headphones I tried.

The sound is exactly what I expected after reading so many reviews over the years. It's very clear, neutral and musical. It highlights any inadequacies of the source material. Low-bit rate MP3s are painful. But it lets you discover your music collection all over by bringing out the details you never noticed before.

I also use it with my computer sometimes. I connect it directly to an external soundcard (Creative Audigy 2NX USB with separate power) and it seems to drive HD600 adequately. I might purchase a dedicated DAC unit later. Also on the wish list is a balanced rig (amp & cable with XLR connectors). It costs about US$2000 but it's supposed to make HD600 sing. The question is whether I can justify the expense to my wife. :)

"Great sounding cans", As a New York recording a mixing engineer I've had the opportunity to listen to quite a few pairs of headphones. The Sennheiser HD600s are the clearest, fullest, and most balanced headphones I've heard so far. While they wouldn't work for a performer in the studio because of the open-air design and considerable leakage, they have become a must-have as a mixing reference, especially when mixing in a new and unfamiliar room.

Grado makes some wonderful headphones that sound nearly as good as the HD600s but the up-against-the-ear design makes them uncomfortable after less than 15 minutes, whereas the HD600s, even with their snug fit, are still very comfortable for long periods of time.

If you know of a better pair of headphones, I want to know about them!

"best I've ever heard. lyrical, sweet, wonderful", I have used these for years and I feel that they are truely wonderful, lyrical, sweet, non-fatiguing.

They are very very detailed without being harsh (a difficult trick). They accurately produce ALL 10 audio octaves 20-20k Hz, and more important, much more important, they are ruler flat, no rolloff in the bass or treble octaves. (Many other components, while claiming 20-20K hz response, have a very uneven frequency response and are rolled off in the high treble and low bass) The highs are sweet and the bass is warm and full without being thumpy. They are also comfortable to wear for many hours. They will show you, with a good amp, exactly what is on the recording, (warts and all if its a bad recording). From what I've heard Sennheiser makes the most listenable headphones in every price class on the market - down to their $25 model 100. I have listened to most of the other brands (without mentioning names) and nothing can touch them.

Beyond measurable stats, they are really MUSICAL and NATURAL. (it's possible to make a product that measures well and sounds dreadful. That show how little the measurments the industry uses actually measure what we hear!)

I have NOT found that the 300 ohm impedience limited their performance. I listened once with a 3 watt vacuum tube amp (yes 3!) and they sounded great, more than adequately loud. I have heard them with Sony walkman, discman.

I have not heard the new model (HD 650) but I imagine it's even better, if that possible. With a good amp and preamp etc, they will give you the sound quality of a pair of high end speakers 100 times their price!


Highest Recommendation. A perenial Stereophile favorite.

"Beautiful Sound, Great Comfort", These are great headphones, given the right environment. The sound is silky smooth, as good as your source material can deliver. Not super efficient, so are better with a home audio equipment headphone jack than lower-powered portable player outputs (though listenable on these as well). These are best used in a quiet environment, when you won't be disturbed by others, and you won't disturb others. Because these are "open" headphones, you can hear sounds around you, and other people can hear what you play on these headphones. This, along with their size and cost, argue strongly against using these as portable headphones - don't bring them on a train or airplane trip.

For over a year, I wore them 5 - 8 hours a day. They were as comfortable as headphones can be, and I heard all sorts of details in my music that I had never heard before. It would be a shame to waste the quality of these headphones by using them on compressed MP3s, because with these headphones, you may well notice the difference in quality.

No complaints at all on acoustics, except that I wish I was more often in an environment appropriate to use them. Occasionally the wires get loose, and one side will lose its input, but one can pull the wire out and reinsert it to fix that.

"Long term Listener, Big Time Value!", I bought the HD 600 from Amazon.com in Summer 2004 and I have never looked back. I use my HD 600 with a variety of inputs; turntable, SACD/DVD-Audio/HDCD/CD and even my Sansa portable player. Everything is still new, fresh and alive sounding even the compressed 192kbps wma files. For most listening sessions I use a simple dedicated headphone amplifier. Two and one half years later and the HD 600 still makes me smile no matter how bad the day has been. Pure audio joy with no fatigue... What else is there to say?

"balanced delight", I'm a professional producer/engineer for 25 years. These are a bargain, full range, and not fatigue inducing.
I'm powering mine with a creek obh 11 and it's beautiful. They're 300ohms - you need a decent amp!
Be warned - the only Sennheiser models I've been able to do critical mix/imaging work on are these HD 600 and
the less expensive HD 555. The other models, 595, 650, etc. are all bumped on the bottom and/or hyped on top. Fine for consumer listening, but a definite no go for audio work.

"Great Product!!!!!!!", I bought It for my husband to use to play games on the computer he says the sound is the best ever.
