Beyerdynamic DT 770 Pro-80 Closed Studio Headphones

Boy, where to begin with these bad boys. I think I'll start with a strong statement: these might be a candidate for best headphone ever made. They have so much to offer it's pretty wild. Probably the best bass I've heard on any headphone. I don't doubt that there are thousand dollar flagships out there that do even better, but in an objective sense, I think any headphone would do incredibly well to get even close to the 770's in this regard. The bass thumps, it goes deep, it has good articulation, it's awesome. Plus it surprises you all the time, because it happens even in music that you didn't think needed bass so much. The thing is, whenever I pull out some other headphones, like the Senn HD58X and I listen to those for a few weeks, I enthusiastically feel like hey that's nice bass! I mean and it really is, the 58X has a very nice bass response. So why do I even bother with the DT770's if I can get bass like this from an open back..? But then you go back to the 770's after a while and the right tracks start coming on and it really hits you. There's just no denying the difference.

The other thing that makes me love this headphone is the almost cavernous feel to the music. It being a closed back, the deep bass, the somewhat withdrawn but highly detailed and smooth mids, the excellent soundstaging and imaging... I do think there is something special about these headphones in that way. All of its aspects come together to really give you a particular sound experience that other headphones categorically don't. Closed backs don't usually come with soundstage, and honestly you can't even keep most closed backs on your head for longer than half an hour, but the latest revision of the 770's is very comfortable indeed. And the sound is just so enjoyable. Vocals are excellent and very well separated, guitars are crisp, violins and flutes are to die for, drum snares are energetic but not too sharp, but mainly it's that you get a fair representation of the actual recording. If something sounds bad, it's usually because the recording has issues, not because there's something wrong with these headphones. There's no shoutiness in the mids, no bloat in the bass, no harshness or grain in the treble, no thinness, no muddiness, nothing. The sound is incredibly cohesive and tight, in a way that contrasts notably with for example the Fidelio X2. The only thing you might criticize is the amplitude of the treble, but it's very easy to remedy. It's so easy in fact that I'm kinda sad to see how maligned both the 770's and 990's are for it, while they're such incredibly good headphones otherwise. I guess that's what you get when you rely on amps rather than EQ to solve problems... Ahum, anyway!

And then you also look at the other aspects of this thing. The affordable price, the light weight, the replacable and washable pads, the reliable build... Every single aspect that could tank an otherwise good headphone is accounted for. No replaceable cable but who needs it? The cables on these old Beyer models have no history of failure.

All in all this is everything a headphone should be. By introducing no problems of its own it gets out of the music's way entirely and lets you simply hear what's there. They're plenty analytical, but they're also engaging and immersive. Pick your ohms version, put on your music and away you go. Recommended for bass lovers in particular, but really anyone who likes audio should probably give these a try.

I have owned two pairs of DT770 Pro’s in my life. The first pair was from when I was a teenager, and the second pair was from last year, in my 30’s.



I didn’t like my DT770’s as a teen. Perhaps I was feeding them the wrong kind of music back then- I was looking for the grandeur of Beethoven symphonies at that age, and those closed headphones certainly couldn’t compete with other headphones I had at the time, such as AKG K701, Stax SR-003, and eventually Sony SA-5000 in my 20’s. Afterwards I got into the planar thing and have owned a couple of Hifimans. You’d think they would totally spoil my ears, but no, I actually really like my second pair of DT770’s.



I noticed the material inside the earcups has changed from this annoying, itchy foam material to some nice fabric. My ears are quite large and do touch that material, so it was a relief to find that it does not irritate my earlobes. I didn’t open them up to inspect the internal mechanics; it’s been over a decade since I heard my last pair of DT770’s, therefore I can’t really comment on whether they sound the same. I also don’t really use them as a pair of headphones for listening to music, but rather a workhorse for on-location recordings.



On a remote location recording kind of scenario, all of the pros of the DT770 really shine through. They are built like a tank (there was a photo of the earcup under a car’s wheel floating around on the internet), and because of the mechanics of the headband, the earcups press against each other when not worn, and this gives me a lot of confidence to just throw them in my gear bag and not have to worry about drivers getting damaged. The comfort is great thanks to the valour earpads, and the clamping force strong enough to make me feel secure during a recording session. This is probably a very personal thing, because I know I like a good clamping force, but some people can’t take even a little force, so please take my words with a grain of salt. The isolation is okay, not as great as Sennheiser HD280 Pro’s, but those Senns don’t sound nearly as good or as neutral as these Beyers.



In terms of sound, there isn’t much to write about. They are neutral enough for location use, sound unoffensive under any situation, has enough resolution for me to make decisions on-location, and generally are a pleasure to work with. I have sampled the contenders at this price range (Senn HD280 Pro, Audio Technica M50x, Beyer DT770) and these are clearly the keeper for me. Large-scale classical music can sound congested on these, but anything from solo to chamber music sound lovely.



I don’t usually listen to music with them (except for commuting, occasionally). Sometimes if I wanted to watch a movie at home, they provide just enough isolation from my cats to provide a good, immersive experience.



About the cable design- I don’t have any issues with this single-entry, non-detachable design. I do have six cats, and I do see some teeth marks on the cable. So far I haven’t had any sonic issues, but perhaps a detachable design (like on the M50x) can be a nice addition, just in case something happens. If I didn't have those naughty companions, I can't imagine anything would really happen to the cable.



I do have other, more expensive closed-back headphones at home, and have tried bringing them to location recordings. However I reach for the DT770’s most often because they are hassle-free, and at this kind of price point, I don’t feel bad to abuse them a bit. 9/10 very satisfied.

                      Beyer dynamic DT770 pro Review
                                                           
The Beyer dynamic DT770 pro-80 ohm headphones is one out of the three DT770 model’s with a low ohm..  A simple sound card like an Asus Xonar DG/X or a sound blaster Z with their headphone amp IC’s will work. The DT770 pro-80 still benefit from a standalone headphone amp.
The DT770 pro-80 is made out of hard plastic’s which in my hands feels like it can take a beating. The Headband pad on the top might work for some people. But might not for others, the weight of the headphone was very light on the top of my head which is a plus. Since my primary Headphone the HE-500 is heavy. One issue I have with the DT770 pro-80 is the ear pads, they are not deep enough for my ears. So my ears touches the driver’s which over time is uncomfortable for me, Also my tip of my ears touch the ear pad top and my earlobe touches the ear pad too. People with smaller ears won’t have an issue with the ear pads.
The wire is very long which is good for when your moving around the room doing other things, when you are listening to music, Or when you are sitting back far from your computer or home audio receiver watching a movie or playing a game.  The wire looks like it’s very durable
 
The Specs
 
 
The Setup
The gear that I will be using for this review will be the Gustard X12 Dac connected to a Burson Audio Lycan thru RCA, which will have the LME49990MA’s op-amp installed, in a two single op-amp setup. The Gustard X12’s USB input will be used. The Lycan is a transparent amp and will let you hear the sound of the op-amp. The reason why I going with the LME49990MA is it is a neutral and transparent op-amp. Which I find so far work well with the DT770 pro-80 letting it shine thru.
 

 

 
 
The Sound
Eddie Bitar – Kaboom (Original Mix)
The song starts off with a lot of bass before strings and then the rest of the beat. In this song the bass is impactful while being controlled, the bass is not one note as there is other tones of bass in the song that is heard, and another part of the song has bass that’s accurate and not impactful.
 The bass doesn’t out do the rest of the freqs and the other parts of the song is detailed and clean. When there’s more instruments they can be heard from each other. The drum kit can be easily heard that starts in another part of the song and the snare is detailed and echo’s away from the center. The sound imaging is good.
 
Kong Speaks – Tooth & Claw
The song starts out with the bass hitting deep with the drum kit being clearly heard alongside with the detailed snares. The bass really sound good in this song. This song is also clear you can hear everything besides the deep bass.  The separation is really good in this song like the first song.
 
Speo – Penguin
The drums and the snares are very clear and detailed at the start of the song. The drums hit hard in the next part of the song. While there is bass it also hits hard and deep, the simple voice note is heard. When the bass stops. The drum kit and the snares are clearly heard and the instrument that playing afterwards sounds really good. Over all I like the way this song sounds with the DT770 pro-80s thru the lycan. Sound really nice. Everything clear.
 
Said the Sky – Clouds
The bass in the first part of the song is kind of impactful but clearly heard and the piano sounds like it spreading thru out the sound stage while having some weight behind the notes which makes it sound good. The electronica note that is playing along the piano sound really good, just like the piano playing by itself is very good.
 
Another part the bass is deep and hits hard and the strings.  Over all I like this song as well being played thru the DT770 pro-80s. There are voices in this song that keeps making me turn around to my door thinking someone said something, or the sound in the first part of the song which sounds exactly like a fire alarm, that reappears thru out the song. Get me really good too.
 
I didn’t think I would get such a bargain with the price I paid for these as I got these cheap. I didn’t know what to expect. I been using them for a week and a half. Originally these was going to be my laptop/tablet headphones. Now I will use the DT770 pro alongside my HE-500s since these isolate really well.

I made a video review of the dt770 80ohm  quite sometime ago and was finally finished it. I got them on sale at Guitar Center for $179.99 , the deal was better than anywhere on the web so I jumped on it. When I auditioned them in-store, I was quite impressed.  I'm not much of an over the ear headphone person, but these were comfortable and sounded amazing.
 
For most of my listening life I've used only in-ear headphones because I live a very active and mobile lifestyle.  
 
As I began to use them more and more I noticed that they weren't providing me the "umph" I was looking for in certain kinds of music.  I also ran into so me issues with sibilance that was bothering my ears for female vocals. Not that it sounded bad, but quite the contrary, they sounded great!  But it seems that my ears are sensitive to that.  I used EQ'd it towards base and fixed many of my issues, in fact it sounded better for my tastes.
 
I've read great reviews about how noise cancellation and noise isolation was great.  They were, but not for noisy environments like a gym.
 
I've read so many great reviews about how it was like having 2 pillows on your head - amazing comfort and amazing sound.  I need more volume so i purchase the creative e1 portable headphone amp. 
 
And I'll tell you that it made such a huge difference.  Based on my experience, if you get these headphones, you need to purchase the this headphone amp.
 
It turns out my head and ears are either too big or too sensitive (probably both).  So it would hurt my temples.  I've asked the forums here and they suggested stretching it out, and it did help a bit, but not enough to justify keeping them.
 
Although my written review here seems a bit negative, my video review expresses my enthusiasm for them - however my issue is that, for my lifestyle, they weren't a proper fit.

1.) Using this on a portable device: IPhone 5s/6/Ipad/Android Phone:
        The portable devices are able to make the DT 770 Pro work, but the result is an emphasis on bass, and the volume is only enough to listen to in a normal environment.  If you're trying to drown outside sounds, you really need an amp.  The high trebles are also not very pronounced with an amp. (Siblance did not occur with portable devices)  So overall use for a portable device is not really recommended.  You'll probably get a better sound and experience from the standard IPhone 5-6 earbuds. 
 
2.) Using this with amp.  I tested with my Yamaha home stereo amp as well as a portable Fiio E12 Mont Blanc.  In both situations, the DT 770 Pro was able to bring out the clarity of the music, and show the depth of the sounds.  The comfort of the headphones wrapped around my hear was so good, I could hardly feel it around it, giving the sound presentation that the music is all around you, rather than a cup stuck to your ear with music pointed in your canal.  
 
The break in for me was about 120 hours before the muffled bass started to level off and the mid and highs started to be more pronounced.   The DT 770 Pro 80 was still more even than the Audio Technica ATH-M50x, with a better sound stage feel.  The DT is also not as bright as the Shure SRH840, especially with the amps.
 
Overall, it's a wonderful headphone, but if you prefer something bright (like you prefer Yamaha pianos over Kawai pianos), then you might want to stick to the Shure SHR840 or the Sennheiser HD598.   If you're more into Rock, then the ATH-M50x.   DT770 is something in the middle, not as well refined as both of the previous cans.  The DT770 Pro 80's equilibrium is well placed just..... slightly south of the mid, with a good reach all the way to the low and most of the highs.

Warning. Not your avaerage audio geek review. Just Joe Smith sort of review. PC sound card drive only. Limited experience with many headphones. But I know what I like. 
 
Well after some happy years with the SEN HD598 and being so comfortable with their use and their sound why would one change? 
Well SHE is more and more in the PC room, more and more complaining about the sound leakage and for my part isolation was zero! 
However the natural sound is unbeatable in my opinion so what are the options? So I was looking around for a closed over ear headphones to supplement the Sen's.
Choice then decision. 
 
The Beyerdynamic DT770 80 ohm arrived and it was hate at first try!
What's going on here. Disappointment plus. Hmmmmm.
Bass sounding lumpy, and isolation I think is poor at first glance. Headband seems a little too tight. 
 
So after a couple of weeks of listening and tuning we have reached a mid-ground area. 
 
Trimmed the EQ on my Aimp3 player to drop the bass in a nice slope down to about 6db, slightly less roll off on the high frequencies. Increased the average drive level as these seem to need much more drive for a given output and lots of listening under the belt, or is it absorbed?
 
Now we can say it is an enjoyable sound, a bit sharper than the HD598, isolation is adequate but not great, level from the MB soundcard adequate. 
Situation in the home is now calm and resolved. She has the HD598 and I have the DT770's. 
 
Who says women are not smart?
 
 
Minsik

DT770 Pro/80  has an excellent bass response and i mean really huge bass! although it is fully controlled and will not leak into mids.
fairly comfortable and easy to drive.
the recessed mid-levels is the only issue for me but it's acceptable. therefore it's not recommended for monitoring vocal details.
soundstage is surprisingly good for a closed pair of headphones.
i wish they had detachable cables but not a major issue for me.
 

I was lucky enough to find these headphones at a pawn shop, buried underneath a pile of beats/bose headphones, and boy am I glad I did.  I rated the value of these headphones based on their Amazon price (which I think is good), but for what I paid, the value is absolutely fantastic.
 
For potential buyers, I'll just point out what I hear, since one man's pro is another man's con.  These headphones have a good amount of bass, and is relatively well controlled.  The mids, especially upper mids, are very recessed.  The treble has a nice sparkle to it, but is a bit on the harsh side for certain music, and tends to get pretty sibilant in the female vocal range.  Basically, as many others have already noted, these headphones have a rather pronounced "V" curve to them.  They are still very fun to listen with, for certain music genres.  Rap, House, Dance, Metal fans should like this phone (Those are the genres I like them for, anyways).  Vocal, Jazz, Classical fans should probably look for a more balanced set.

Words can't do it for me, i went from a cheap headphone like the JBL Tempo to DT 770s , it would be an understatement to say it was a night and day difference.

These are are really versatile, i listen to EDM, DNB and kinds of electronic music along with Metal, Hard Rock, JPop and these haven't let me down, i heard about these having recessed mids and are kinda bad for classical music, but doesn't really bother me as i don't even listen to classical.

Initially the Bass on these is a little over the top but still controlled, give em some time to get burned in and the bass gets tighter and the highs become more prominent.

All in all, if you are like me who wants a fun headphone which can give you all the bells and whistles while still being highly detailed then look no further, these are for you.

Ah almost forgot, these are also very very good for gaming, the soundstage is really wide despite these being closed cans.

Sorry for no actual review as i have just got into audio recently and this is my first pair or good headphones. But even i could tell there was alot of sub bass not loud but its definitely noticeable.

Hey All,
 
This is my first head-fi review and I am proud to say that these Beyerdynamic DT770 Pro 80 are wonderful!  I currently own a pair of Bose QC2 and the ATH-M50x and wil be using those to compare.
 
The 770s are built tough, rugged plastic and mostly metal here.  The velour pads and headband seem sturdy enough and I have already seen you can buy replacements from Beyer for quite cheap.  The build on the M50x and QC2 are mainly plastic with the only real metal being in the headband.  They are still well built and nice looking though, nothing against them.
 
The Dt770s leak a bit more sound because of the velour im sure but both do a good job of blocking out noise with the edge going to the M50x here.  
 
In terms of sound quality I am not sure if I know all the right terms to describe it, and I am still training my ears as I am new to the hi-fi world but I will give it a shot.
The DT770s have crisp, clear highs.  I can hear more minor detail through them in terms on hi-hats and clicks and whistles like that than on the M50x.  The simbalence (not sure if right term but the piercing notes) can be a little harsh if played loud but I have not been bothered.
 
The mids of the Dt770 are more forward and noticeable but compared to the M50x the detail seems to be similar just more recessed mids on the M50x to my ears. I really love listening to rock, indie/folk on them because of the more forward mids allowing me to hear guitar and vocals better.  The M50x mids are still very nice however and I am not bashing them.
 
The bass of the DT770 is great.  It extends very low and does not roll-off on the low sub bass which is great for when i listen to my dubstep like Skream.  It is punchy and impactful and does not seem to suffer from too much boominess.  The punch and impact seems a little stronger on my M50x but it is better controlled on my DT770s.  Either way, both are known for the bass they produce which is why I went with the 80ohm version over the 250ohm But I am very interested to hear how the 80 and 250 sound side by side now.
 
The comfort is great for the Dt770, I had some uncomfortable pressure on my left ear for the first week or so but now I can wear these for quite some time without having to adjust at all.  My M50x however I find much more uncomfortable for longer uses.  After about 30 mins I have to ajust the headband around as no matter what I do i cannot seem to get rid of the pressure. 
 
I power both of these currently with the fiio e6 but I am soon upgrading the schiit magni/modi.
my sources are spotify premium and itunes but I cannot wait to start building a lossless collection of some sort
 
Overall I could not recommend these enough, I managed to find mine for $130 on cyber monday but if you can find these for about $200 I would go for it over the M50x because of the comfort and better mids.

So I bought this BD DT770 pro because I am in the middle of mixing the tracks we've recorded with my metalband. Because I am a truckdriver, I spend a lot of time in my truck, dragging along my laptop whereon I do the mixing. I definitly needed a good headphone for studio use. By doing some homework I decided that The DT770 pro was the one I couldn't go wrong with, so I ordered it.
 
Before these headphones I owned a Pioneer SE650 and a Sony MDR CD570. The Sony is decent but a bit too strong in the treble departement and has good subbass but not enough mid-bass. You can imagine that the DT770 was a huge step up for me. It's tradionally build, with a steel headband covered with a removable padding, big sturdy plastic cups, velvet removable earpads and an old school adjusting system with clickpoints.
 
The sound was the best i'd ever listened to and I was really happy with it. It has only been used on the laptop and to do the vocal recordings on a multitrack BOSS device. The singer never heard a better set of HP than this one !
 
But it was after a bought a used AKG K271 studio, it's in the same price catarory, that I realised it's flaws.
The DT770 has this soft, almost absent, mids. This results in mixes with too much guitar in it. It also has a stereo image that seems to put instrument outside your head instead of inside. This is hard to explain for me and very subjective. But the image is completly different compared to the AKG, which seems more logic to me.
 
Bottomline: great headphones but not the best, in the pricerange, for my needs.

Was looking for a overal headphone (I mean one that works with all genres of music, movies and gaming) that didn't needed extra equipment like amp or dac, a headphone for a lazy person.
And of course a bang for the buck.
 
Let me tell you I found all that in the Beyerdynamic DT770 Pro 80.
 
Plug it in your pc, hifi set or portable and it starts doing its thing; sounding great and let you have fun listning. Doing this it's also very comfortable on your head for a long time.
Tried it with mainly music genres like classical, jazz, blues and rock. It's just very fun. Maybe the classical it could be a bit more "clean" in its sound.
With movie and game its a perfect match.
 
Then I added a dac/amp, the FiiO E10. This really showed me what the DT770 was capable of. So much depth in its sound.
 
Of course you can find better sounding headphones, but in this pricerange its a star.
But, every headphone has his own sound and it can be a matter of taste. This one is, so I thought, very couloured in its sound. You like it, or you don't.
I love it.

 
Sound:
This is what I wrote about the 250 Ohm version... "Overall good sounding. My DT880 might sound somewhat more refined in the mids and highs, but in the lows and especially in the low-lows the DT770 beat em. They are probably my 2nd favorite closed headphone, right after my beloved Denon AH-D2000 (which seem to outperform all other headphones I tried). I think it's a good idea to EQ this cans, by slightly raising the mids and minimally taming the highs you can really improve the sound of this cans."
 
Amazingly the 80 Ohm version sounds even better to me as the bass has even more impact and the mids + highs sound smoother. I love em!
 
Comfort:
The DT770/880/990 Pro are the most comfortable cans i tried...
 
Recommendation:
If you are looking for "sanely priced" closed cans capable of delivering a good amount of bass but still sound good overall, get em!

Spoiler Alert:
I like them
 
Link to thread: http://www.head-fi.org/t/658422/ich-liebe-dich-dt770-pro

Well, I  was looking for raplacement of my HD380 PRO at work.
 
The environment:
 
- music type: heavy metal (Slayer, Kat, Metallica, Paradise Lost, My Dying Bride, Candlemass, etc...)
- music source: laptop flac/high res m3
- DAC: Fiio e17
- AMP: depends: Fiio e17 or Fiio e17 docked into Fiio e9.
 
So, in comparison to HD380PRO, I find  DT 770/80:
 
- weaker in bass 
- better in mids
- better in highs
 
So probably I will not win Nobel prize quite obvious...
 
Overall hearing dynamics of HD380 is much better then DT770/80. however:
 
- HD380 just crashes my head with bases, while DT770/80 simply delivers it
- HD380 is much less comfortable after 1hr+ listening then DT770/80. Much. Really MUCH. 
- Mids were much better in  DT770/80 then in HD380
- Highs were much better in DT770/80 (I was able to hear separate clappings in concert recordings, while on HD380PRO I only heard noise)
- BUT!!! - HD 380Pro provides much more power of the sound. It is simply louder and much more dynamic... MUCH more then in DT77/80 case
- It is very hard to adjust EQ and AMP settings to different records in DT770/80 then in HD380 case. DT770 seems to be very very sensitive to EQ and APM settings, while HD380 takes anything and plays good.
- isolation of HD380 seems to be a TARGET which other closed headphone might only wish to reach (I use DT770/80 at work, and my collegues claim that they are louder much more than HD380PRO).
 
 
In general - DT770/80 gave me much more details what is happening in mids and highs. The sound is very clear in comparison to HD380PRO.
 
Am I satisfied ? NO. I expected much more power and more loudness&dynamics. So sooner or later I will find appropriate CLOSED headphones stuff.
 
 
 
 

These cans were my first set of higher fidelity audio and since been have been enjoying music much more because of what they bring to the table. I have owned these headphones for about 2 years now and they have a decent amount of use. Unfortunately when i first bought them, my only extra piece of audio equipment was a FiiO E7. But recently I bought the FiiO E9 and a Schiit Audio Modi DAC. That pairing has even more so brought up the potential in these headphones. 
 

 
Treble/highs
Nice, it is non-fatiguing which makes listening to music on these very easy and enjoyable for hours. The highs are clare but a little rolled off. They have a good sound to them and because the cups are so large, the instrument separation is quite nice for a closed back pair of cans. 
 
Mids
Unfortunately this is the worse part of these headphones. Not to say the mids are terrible but they could be much stronger. They are recessed and not as clear as the other spectrum. They are not colored and sound quite neutral but they are not impressive. I also own a pair of Shure SRH 840's and those blow the Dt770's clarity and mids out of the water. I love my beyers but for most everyday listening i prefer the shures
 
Bass/low
This is where things get quite good, i bought these headphones for the bass. I was going to get beats (SO ******* HAPPY I DIDNT) but my friend told me about this website and to check out these headphones and i am beyond grateful for his help. I love the bass on these cans. Because they are not the most efficient and easy to drive phones they will sound good not great coming from a laptop or phone but connected to my amp.... they sound pretty damn good. I love some house music or electronic, these cans really shine in that respect
 
OVERALL
they are a great pair of headphones and are well worth the money just for the headphones. Oh and did i mention are they build like a tank... they are some of the most comfortable headphones i own and love using them for their main purpose. If you are looking for a more efficient and everyday pair of phones, check out the SRH 840's wont regret those. As for these, they are fun and a great buy for what they offer. True German Engineering

 
[size=13.0pt]While they have a slight v-shape to their sound, I would not say mids are overly recessed, to where the sound suffers. I love the sound for the music I listen to! Build quality is really good and they have no visible signs of damage. Comfort is a big deal with these particular cans, the large velour ear pads are amazing.  [/size]

I am not an audiophile but I have some basic knowledge so forgive me if I make a mistake.
 
First of all, these headphones have a very excellent design and the build quality of these is outstanding. I can easily see these things lasting a long time.  The comfort is very good as well due to the velour pads and giant earcups but I found they clamped too hard.
 
These are certainly a bass lovers headphone. Bass is fun sounding and has good impact while being tight and controlled. The treble is just a tad sparkly. The mids are probably the weakpoint as they are shadowed by the bass. Soundstage and imaging is great (almost fantastic). These things like a LOT of burn in. They really start to sound good after 100hrs of burn in.
 
I really enjoy these headphones. These could be the last headphones you ever own. I would recommend them if you like something more fun and engaging.
 

[size=small]If you listen to music at work or at home and LOVE LOVE LOVE to hear the minutia and background details of your music, then this is the headset for you! While many headsets from $200-$500 deliver amazing music, very few, if any, separate the music quite as well as these headphones. They create a sound stage that is hard to beat.[/size][size=small][/size]
[size=small][/size]
[size=small]If you are familiar with the car commercials where they show you an engine working, then the moving parts fly apart while still working.... other headphones deliver the engine/music-which is nice but these headphones make the instruments fly apart! Most places that carry these headphones have a return policy... do yourself a favor and at least listen to these headphones before making a choice.[/size]
