Sound Quality did not disappoint.

The quality is phenomenal

Honestly out of the box the sound quality was great, definitely some of the best I've heard from a number of headphones and at the price range knocking out with ease even other more expensive ones

The sound quality was infinitely better than when it was plugged into the mixamp, which is the exact opposite of what I expected

To get the optimal sound quality for these phones, I use a mp3 software player capable of ASIO or WASAPI playback

Second, the build quality as new seems on par with the current asking price, but I do wonder about long term longevity since the plastic, while thick, feels kind of brittle.

Overall the headphones are comfortable, of good quality and easily maintainable to address long-term wear-and-tear (earpads, etc) issues

The build quality is great, though they are a bit more plastic-y than I would like

The cable is detachable and is very good quality

awesome quality headphones .. but with that huge price tag, it's quite an investment.

Well, initially it was to ensure that CD's produced as good a quality as the analog phonograph records - and that was the competition

Unfortunately very few recordings, especially mainstream commercial ones, have really good sound quality.

THEN I started to appreciate the DVD quality

I was skeptical before my purchase regarding the quality and look as it was open box

Pretty good sound quality, very crisp sounds

Sound Quality is incredible, and imaging is so good you can often times hear how the drummer has his kit set up

These are headphones that revolutionize all the music YOU ALREADY OWN!But be warned: remember how when CDs first came out there were all those pretentious warnings about how the superior quality of the recording may expose flaws in the master that you could never make out before

Sound quality is A+ and I suspect that these headphones will last for years to come.

Great sound quality and they are very

If you are listening to digital media, you will want to make sure that your music is encoded with sufficient quality.

The open back style headphones are honestly incredibly important for having a good quality sound, too, and I don't think I can ever go back to closed ones.

Everything about the sound is quality and each level does not overwhelm the other.

excellent quality

Sound quality is simply amazing.

The board still drove the cans, however they were not giving me the proper $300+ audio quality experience

Definite must haves for audiophiles and those seeking great sound quality.

The quality of sound is outstanding, highly recommend these

The audio quality is superb, with good detail and extremely flat response.

I mostly use the headphones with an iPod Classic 160Gb, a Pioneer VSX-23TXH AVR, and sometimes with an old Dell laptop, all of these sources provide marvelous sound quality

The HD598 have been my favorite set for that energetic quality, but they can only handle so much

These are headphones that revolutionize all the music YOU ALREADY OWN!But be warned: remember how when CDs first came out there were all those pretentious warnings about how the superior quality of the recording may expose flaws in the master that you could never make out before

and I love this quality in my headphones

They are very comfortable and the build quality seems solid so far

In my opinion the quality of the sound improved by about 30-50% depending who you are and how unblocked your

There is a difference between great sound quality and extremely loud volume levels, and only those people that want very loud volume levels will need an amplifier in addition to their portable player

I always used Sony headphones since the sound quality is quite nice and it is priced reasonably

soundRelatively cheapBuild quality is phenomenal

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

However, make sure you have decent quality music or they will exaggerate the "bad" in the quality

The static and distortion in anything lower quality will be really annoying

unbelievable sonic quality, never thought a headphone could sound so good.

Terrific sound quality

The sennheissers can deafen me quite easily as it stays clear and unstrained WITHOUT boominess until the loudest levels thereby you sometimes don't realize how loud they are until you take them off and go DAMN!Build quality is very good

I am still astounded by the amazing accuacy and quality these headphones produce

Honestly out of the box the sound quality was great, definitely some of the best I've heard from a number of headphones and at the price range knocking out with ease even other more expensive ones

Also the build quality and packaging feel excellent, but it's hard to give an honest review of the build quality after only a few weeks of use

By far the best audio quality i have ever owned

Amazing Quality Headphone when paired with amplifier.

The velour pads feel awesome and the sound quality is much better, than any other headphone I have

Once you start to use the Sennheiser HD 600 headphones, you will most likely feel that this was one of the best music listening headphones at the price point of approximately $350.00.To obtain the maximum sound quality of the Sennheiser HD 600 headphones, you will need a good quality stereo pre-amp and or stereo amplifier

An excellent pair of headphones from durable quality of construction to incredible bass and clarity.

The sound quality is excellent with everything I have plugged these into and in my opinion most adults will be more than satisfied with the volume level an iPod, laptop, or other portable player will produce

Overall I'd call it a laid-back listening experience, the highs are detailed but not fatiguing, and the bass is good quality but not overemphasized

Very neutral but still manages to be fun with a surprising amount of rich high quality bass

Excellent sound quality, good cable size, not that beautiful but not ugly

The build quality is good, I've dropped them and snagged them a few times and are still in perfect condition.

These also require good quality ancillary equipment to shine, just like the HD 600's

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.

It just adds to the richness/quality of the overall sound.

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

Great quality sound

These headphones are the current best quality headphones on the market (without spending $1000+)

If they were all u had to work with

I have around 7 pair of professional/audiophile headphones and these are as good as it get's in my opinion

i really wanted a very nice pair of headphones for checking my mixes on as well as for listening to music on without throwing off my ears

In short: These are as good as it gets -IF- if your reason for wanting headphones doesn't include recording

I use these in my home studio for late-night composing and mixing, as well as for pure enjoyment.

These headphones handle it all as well as you can imagine, and will expose items in your favorite songs you had never heard before.

Not to mention their open-back design and 300 ohms of impedance mean you shouldn't be using them while traveling, though this doesn't bother me as I use the at home

Although there has not been sufficient time for burn-in the phones are superbly accurate (especially in the midrange: vocals, woodwinds, etc.) as well as in the wonderfully detailed highs (in an odd turn of events I happened to find that the HD 600 was not much less in the highs than my Koss electrostatics)
