Beyerdynamic DT 770 PRO Closed Studio Headphones - 250 Ohms - Reviews
Pros: Excellent timbre, Wide SoundStage (for closed headphones), Engaging, Cups Built Solid and Price.
Cons: Headband, way too small and materials of the headband are cheap.
(Review is based off the addition/swap of/too Dekoni sheepskin leather pads)

Before I slapped on the leather pads these things were treble happy.. treble was front and center no matter what you played. I'm not a fan of electronic EQ so I did it the ole fashion way,,, LEATHER PADS. This helped tame the treble to exceptable levels and the treble is nice by the way.

I'm not gonna write a thesis here, quick review...

The purpose of this headphone was to get a "peek" of the Beyerdynamic "sound". And I love it. I chose closed back because my headphone system (office) shares with my two aquariums.. (hey..what can I say.. ) and.... the 250ohm picked to match up with my OTL Tubed amplifier,Darkvoice 336se.

This headphone is opposite of the Drop Sennheiser HD6XX. Where the Senns are warm and laidback...the Beyers are fast and vibrant.. I can EQ the sound of the amp by switching out a combination of tube types, (which I do almost on a daily basis). The bass rolls low with the Beyerdynamic (in a controlled manner) and never over done, everything stays even. If your a Radiohead fan, these will melt your face. Because of my infatuation with tubed amplifiers the Beyerdynamic has been my most used headphone. Beating out the Sennhieser, Hifiman 400i, Fedelio X2, and Fostex T20RP.

Pros: Excellent bass and sub-bass, comfortable, light but sturdy, inexpensive
Cons: Some compromise in midrange, colored tuning not ideal for all genres
The evolution of headphones has been fascinating to watch over the years. Pretty much everyone aged 50 and younger has grown up using headphones, and have owned many, many pairs. Some may remember the crappy headphones that came with the original Walkman and its progeny that would usually break long before the foam covers would wear off. They were an afterthought, although Sony’s 1979 introduction of the 3.5mm “minijack” stereo connector was useful. In some ways things haven’t changed much since then, as headphones associated with portable audio is still considered disposable. Good full size “over the ear” headphones existed of course, but were mostly used by audio professionals and audiophile hobbyists with almost art-deco/mad scientist looking tube amplifiers.

In 1985 Sony once again was a step ahead when they introduced the MDR-V6 studio monitor headphones. They were not obviously revolutionary compared to the standard of headphone technology at the time, but their immense popularity with studio and audio professionals expanded to general consumers who realized their flat sound (meaning accuracy), sturdiness and portability was a great value for the price ($70). But not everyone wants completely neutral sounding headphones. In order to enjoy relatively bass heavy funk, dub & dancehall reggae, hip-hop and dance music (especially drum ‘n’ bass and later, dubstep), DJs in particular craved headphones that could simulate the immersive low-end sounds. Again, Sony responded in 1993 with the MDR-V600, which emphasized bass and featured swiveling earcups so DJs could easily switch to one-ear listening. And while previously most quality full size headphones traditionally had high impedance (100-600 ohms), the MDR-V600 was only 45 ohms, which meant they could be used without an amp on portable tape and CD players with decent loudness and sound quality.

In the years since the explosion of iPods and MP3 players, there’s been a reaction to diminishing returns in sound from poor quality sources and transducers (cheap inner ear headphones and computer speakers) that’s manifested in a growing number of people going back to buying records (they really just need lossless files and decent speakers, but I cover that elsewhere), and using better quality full size headphones. The audiophile market seems to have responded to the demand in the past decade, and often exploited it. Around 2003-07, the flagship models of headphones by industry leaders like AKG, Sennheiser, Beyerdynamic, Denon, Audio-Technica, Ultrasone and Grado were priced around $400 to $650. There were a few exceptions of more expensive models, including Sony’s MDR-R10 which sold for several thousand, but that became more common in subsequent years, with most manufacturers, including newcomers Hifiman and Audez’e, offering headphones for well over $1,000. Perhaps fortunately, almost none of them were really made for rock music, working best with classical, jazz and folk. And when it comes to metal, when very few bands of that genre are big selling superstars, it just seems wrong to listen to their music on cans that might be more expensive than the instruments they played with.

There’s a number of sub-genres of metal and heavy rock, which I often clump together as “stoner/psych/doom,” that emphasizes fuzzy low tones and bladder-shaking bass that would benefit from some headphones that do the music justice. Cans of doom! There’s no shortage of bass-heavy headphones, but most of them are models of poor quality and bad value. It’s hard to get heavy bass without being too boomy or just flatulent and all over the place, and sacrificing quality of the mid-range too much. Bose has long been the whipping boy by audiophiles, and more recently, Dr. Dre’s Beats By Dre have become the most common example of bad quality and value. They’re also hugely popular, and while they may serve as a gateway to better things for many people, they’re also a huge rip-off, especially with Beats Studio at $300. So what’s a rocker on a budget to do? Skullcandy’s Aviator offers better sound at half the list price ($150), though again, the quality might not be quite there. Next week they’re issuing a special Dinosaur Jr. edition along with the release of a single. Lemmy Kilmister has his own series of vanity cans with Swedish company Krusell International AB, with the top model, the Motorizer, selling for a more affordable $129. With endorsements from rockers across the globe (who wouldn’t want to support Lemmy?), they should sell well. I haven’t gotten to hear it but Lemmy’s m.o. to “make them louder than everybody else’s” is not exactly promising.

Surprisingly, at least to some people, you can get audiophile quality cans that will do heavy music justice at comparable prices to the mass-marketed Beats, Monsters, Skullcandy and Motorheadphones, while also putting sufficient boom in your doom. I’ve been lurking and participating in the Head-Fi forums for close to a decade, and the favorite headphone for general rock listening is the Grado SR-225i. I heard it while researching headphones, and while it excels at conveying the excitement of mid-range guitar sounds, it lacks low end depth, and can sound harsh and irritating, causing fatigue to occur quickly, within 15-20 minutes. On top of that, they’re uncomfortable and look like they were assembled in someone’s garage. Clearly I’m not a fan, but they do have their use for certain people. Just not us heavy psych and doomsters. For that kind of music, the favorite by a significant margin has been the Beyerdynamic DT 770. The company is considered one of the German headphone giants along with Sennheiser for good reason, having been around since 1924. In addition to featuring boosted “bass-reflex” technology, the DT 770 was considered since 1985 as one of the best overall sounding closed-back headphones on the market, and listed at only $250. It was discontinued in 2011 and replaced by the T70 which uses Tesla technology from their flagship T1. Unfortunately it’s priced much higher ($649) and does not share the bass characteristics of its predecessor.

Luckily for bassheads and rockers everywhere, the DT 770 Pro model is still available, and for just $179. I treated myself to a “like new” used one for my birthday for $133, a great bargain compared to the T70 and the $1,500 T1. For the past few years the Denon AH-D2000 has been my workhorse in my doom cave listening lair, and the smaller AH-D1001 in the bedroom. They are an excellent choice for rock music, with a healthy amount of bass that would satisfy anyone but the worst bass junkies. In his piece “The Battle Of The Flagships,” Head-Fi Guru David Mahler said, “The DT 770 really digs down deep with tremendous impact. Despite this, its bass presentation manages to be rather tight. What may be most impressive about the DT 770’s bass presentation is that it really is able to bring forward the sub-bass frequencies that many headphones skimp out on.” Unfortunately that Denon series lost their license with Fostex, who created the designs. The line has been discontinued and replaced by the AH-D600 Music Maniac ($550). Being brand new, I was unable to find out much information on it, and I’ve been wanting to try a Beyerdynamic anyway. I wasn’t disappointed. As promised, they are bass heavy without being completely overwhelming. The mids are somewhat recessed, making for a “dark’ sound signature that’s perfect for most heavy psych and stoner/doom metal. The bass on the new Goatess album sounds insanely over the top, and great fun. Previous listens to Age Of Taurus‘ Desperate Souls of Tortured Times seemed a little lacking in bass, and the DT 770 helped remedy that. Sessions with Black Sabbath (new and old), Saint Vitus, Magic Circle, Rote Mare, Jex Thoth, Elder, Electric Wizard, Wo Fat and Pagan Altar all benefited from the cans of doom! They’re definitely not neutral reference cans. They are available with three different impedance ratings (32, 80 and 250 ohms). I got the 250, which would sound very quiet plugged into a computer or MP3 player, but come alive on my home Meier Corda Catante.2 amp. I love this amp, with crossfeed features that helps prevent listening fatigue, which I discuss more here. That one is discontinued, but he has newer models that are even better.  Some DT 770 owners like the portable Fiio E10, which does not have crossfeed.

A close runner-up in the cans of doom category is the Ultrasone HFI-780. While it lists at $279, it’s available new on Amazon for $155, and used as low as $120. I was unable to hear these myself, as no one’s gonna be sending me free review headphones, but lots of people with large headphone collections swear by them. For portable listening, you can’t go wrong with the Audio-Technica ATH-M50 ($199/$159) sturdy studio pro headphones that fold up nicely, similar to the venerable Sony MDR-V6 and V600, both of which are still available for $80 and $250 respectively. But for cans of doom, you can’t go wrong with the Beyerdynamic DT 770 Pro.

Pros: - Lovely bass response - do need bass boost imo -detailed and rich sound
Cons: - yes you need an amp - some sound leakage
I love the Beyerdynamic dt770 250 Ohms.  After searching high and low for a closed back headphone I fell upon these knowing that I would carry an amp.
With the Cayin C5 - High gain at about 2.5 volume and yes, some bass boost - they sound tremendous.  I feel an impact of the bass, I feel a sound stage, I hear vocals and I'm enveloped in a lush sound.  Great for instrumentals.  Great for well recorded music, great for all genres.
However they do leak some sound.  Be prepared, you won't hear the outside world but if it's quiet around you, the outside world shall hear you.
That being said, go for these, get the Cayin C5 and be happy.
If you need to drive it from an unamped source they will sound a tad harsher BUT still great.

Pros: Bass controlled but little boomy, Treble very good but little harsh
Cons: Small soundstage, recessed mids, Ear fatigue and sweating, Non removable cable

Pros: Build, comfortable fit, replaceable parts, price, clarity and warm of sound, clear bass
Cons: TBD
As a beginner to higher-quality cans, my only comparisons for the DT 770 Pro 250 ohm are against a pair of Audiotechnica ATH-M50s and your standard Apple earbuds. That being said, it's not fair to say there is even much to compare, whereas the 770's are the complete package. 
Purchased the 770 250 ohms from Amazon for $187 and have only had them for four days now. Coming from the M50s, I also upgraded from the Fiio E6 to E12 so I could properly drive the 770's. Although I was really grooving on the M50s, I didn't always feel they had the warmth and bass I wanted, nor did I care for the swiveling cups. When looking to upgrade, I decided on the DT 770 250 ohm package based on the head-fi review of 770 880 and 990s found here - Though I looked at several other sets of phones before upgrading, I was primarily sold on the 770s based on reviews for build, style, and price point. As a newb, I wasn't quite certain what to expect from audio compared to the M50s.
Again, with only 4 days in, my initial response if 5 stars. 10 hours of burn in last night with pink noise from a FLAC audio source. 
The bag these came with is acceptable, though I'm already looking for something better and more sturdy for traveling. Given I travel extensively for work, these are designated as my go to headset and want to ensure they're well protected through air travel. 
Lightweight, yet solid enough to know they're built to last. Compared to the M50s, the 770's are definitely lighter in overall weight and I was a bit surprised by the almost hollow plastic feel of the external ear cups. To be honest, my first holding of the phones was a little disappointing based on this. If you've tried the M50s, you'll know how solid these are. Overall build of the 770's is good and furthered by the reviews and ability to replace every part, put me at ease. Velour pads are AMAZING... wore these through 8 hours of travel in the past week and they were no less noticeable at the end of 8 hours as they were at 5 minutes. Comfort is absolutely perfect and beats the M50s hands down. 
As a newbie to quality headsets, I'm not familiar with the technical parts of headphone reviews from an audio perspective; however, I can attest to pure and simple beautiful sound from the 770's. The bass is warm and full, but not over pronounced, wherein I felt the M50s were lacking in bass in general. It was there for sure, but didn't really make the listening experience any more enjoyable than normal. With only a few days in on the 770's, the bass is one of the areas currently pleasing me the most. Second area of noticeable interest is the pure clarity, making every instrument distinguishable in every song. This fact alone has shown me a few bad recordings or poorer bitrate songs in my library that I'm not combing back through and upgrading to FLAC.
Given more reviews on head-fi for burn in periods, I put them through 10 hours of pink noise and have yet to test them out again to verify any increased performance. As such, I'll follow up again once I have more time with them. 
Though currently powering with the Fiio E12, I'd welcome any advice for better amplifier that may have a combined DAC. I'm primarily running these off my iPhone 6, but have been questioning picking up an X3/X5 to get better sound quality with amp so I'm not at the mercy of a secondary amp with cables. 
I am glad that you are happy :) I also you 770's daily

I wonder how they compared to the senn hd580s?
Pros: Sound quality, comfort, price
Cons: Need to be EQ a little
Really perfect sound quality for this price! And headphones are extremely comfortable!  
A little bright in highs, but it can be easily corrected with a little eq tuning. 
For that people who founds sound a little bright and sibilant I highly advise to try Equalizer APO with the following EQ configuration:
Preamp: -2 dB
Filter 1: ON PK Fc 32,0 Hz Gain 3 dB Q 1,50
Filter 2: ON PK Fc 50,0 Hz Gain 2 dB Q 1,40
Filter 3: ON PK Fc 80,0 Hz Gain 2 dB Q 2,00
Filter 4: ON PK Fc 125,0 Hz Gain 0 dB Q 2,00
Filter 5: ON PK Fc 200,0 Hz Gain 0 dB Q 1,50
Filter 6: ON PK Fc 300,0 Hz Gain 1 dB Q 2,50 
Filter 7: ON PK Fc 500,0 Hz Gain 0 dB Q 1,50
Filter 8: ON PK Fc 750,0 Hz Gain 0 dB Q 1,50
Filter 9: ON PK Fc 1200,0 Hz Gain 0 dB Q 1,50
Filter 10: ON PK Fc 1900,0 Hz Gain 0 dB Q 1,50
Filter 11: ON PK Fc 3000,0 Hz Gain 1,5 dB Q 5
Filter 12: ON PK Fc 4600,0 Hz Gain 1 dB Q 5
Filter 13: ON PK Fc 7000,0 Hz Gain -3 dB Q 3,50
Filter 14: ON PK Fc 9000,0 Hz Gain -2,2 dB Q 6,50 
Filter 15: ON PK Fc 11000,0 Hz Gain -1,1 dB Q 5,50
Filter 16: ON PK Fc 14000,0 Hz Gain -1 dB Q 4,50 
Filter 17: ON PK Fc 17000,0 Hz Gain -1 dB Q 5,50
Pros: sound, comfort, price, build quality
Cons: non removable cable
These sound as good as the closed designs can get, imo. They are quite flat. Sure, not the very best out there, but for this price point, you won't get better. They are closed, so you can't expect such airy sound as from open back designs, but they do sound fantastic, and don't get too warm (can't speak for the leather version), but they isolate the sound better. Of all the headphones I ever owned, the beyerdynamic build is just the most comfy for me. If you want a reference set of cans, I'd reccomend these guys. If you want to add some umph to your music, you can always fiddle with amps or eq. The only downside of them is the non removable cable, really. At 250 ohms, even the mobile phone amps can drive them reasonably loud (don't confuse impedance with loudness). Also, you don't really get any accesories, a silky bag, i think, that's it. Not that you need them, but all the money goes into cans, and not the packaging, I guess.
Pros: Amazing isolation, clean highs that does not pierce !
Cons: Headband clamping, muffled lo end, spatial resolution is sub par.
I bought my first pair of these headphones blindly as a student, based on the recommendation of my lecturer at SAE more than a decade ago.
It took me a while to get used to it, but I haven't looked back ever since. Perhaps its what I got used to, but the fact remains that I can trust the sound of these headphones to get a mix out without second thoughts. There was a time when I thought I'd get myself a 'better' pair of headphones. But I ended up getting a second pair of these bad boys after the first pair of these gave up after a long 6 years or so of constant use. 
I recently (finally) moved on to an open back headphone that I prefer over this pair, but that is not to say this headphones is any inferior. For the price, this is the best headphones one could find. They say the best camera is the camera you have with you. I say the best headphones is the one that you know, the one you can relate to.
For me, DT770 is #1 when it comes to the headphones I - know - the sound of. I do highly recommend it.

DT770 love <3
What are your new open cans?
Pros: Awesome with every kind of music, super deep and controlled bass, crystal clear highs
Cons: Headgrip is a little too strong right now, needs amping
To this day, I have owned a couple of "pretty good" headphones (in my opinion pre-DT770 
* Sennheiser HD555
* Sennheiser HD448
* Shure E2-C IEMs (lost/stolen)
* Ultimate Ears Super-fi 5 IEMs (lost/stolen)
I also own an Fiio E7 DAC/amp, which I used along with my HD448 at work.
Needing a closed headphone for work, I decided ot purchase a pair of DT770 250Ohm after a lots of reading on here and arround the web. So, I've pulled the trigger on those and the much praised Modi/Magni duo. I actually got the Modi2/Magni2 straight from Schiit's website (note to all canadians: they might not be as cost effective to us with the new USD/CAD change rate and duty import taxes - a suprisingly high 75$ CAD, ouch!).
So, yesterday I finally received my Modi 2 + Magni 2 and today came my DT770 250ohm.
So, my expectations were pretty high after reading so many reviews and impressions; I've have always found the Sennheiser sound signature to be pretty awesome for mid and highs, and totally lacking bass. Being what you guys would consider a basshead, I've been disapointed a lot with the HD555 ever since I've had them (5 years+). I've do appriciate them a lot more with jazz/cuban/electronic music, much less so with rock/hiphop/dubstep, because of the lack of deep controller bass.
Impressions / mini-review
Now for my impressions. When I toyed around with the modi/magni yesterday with my Sennheiser cans, I was somehow afraid I would be disapointed with the DT770. I truly couldn't see any difference between my Fiio E7 and the modi2/magni2; my set of HD555 is only 50Ohm impedance, so it doesn't really benefit from being amped.
But today, I finally got to give a try to the DT770, and holy ***, those things are simply awesome! I've never listened to anything sounding as clean and tight as those. The bass is so precise, deep and controlled. The highs are at least as good as the HD555 (which I can't A/B test right now, left them home), and those cans truly make the HD448 feel and sound very cheap. It's simply in another league.
The build quality is, like said many times before, very solid. And the comfort is pretty good. I kinda feel like they grip a little too much, but I'm sure it'll loosen up with time. Oh, and the sound isolation is exactly what I wanted: very close to IEMs in isolation level, but much easier to remove/put on the cans; which is a must at work when a coworker needs my attention.
And finally, I can actually appreciate *any* type of music with those cans: from hiphop to jazz, it just doesn't matter. I really don't mind them having a V-shaped sound signature, I guess; I just use the DT770 without any sort of EQ and the sound signature fits my taste. So, that's it for now. I'll post more impressions as they get burned-in and as I listen to them more.
Note : My source is a retina macbook pro, 256/320/16bit mp3s mostly, tons of 16bit lossless FLAC/ALAC, and some 24bit lossless alac rips from SACD. I'm using iTunes on OSX, with the OS setup to output 192KHz/24-bit signal to the modi2 through a fairly cheap USB cable (I got some 32awg coming from monoprice, but I really doupt those make a difference at all). Oh, and I got the Psyst RCA cables from Schiit to to connect the modi2/magni2.
PS: Sorry about my most likely bad or lackluster use of adjectives regarding my audio impressions, I'm french canadian so bear with me :wink:
Pros: Quality materials and craftsmanship. Extremely durable. Very comfortable for a closed design. Excellent value.
Cons: Slightly laid back mids.
My Setup
Tested with my Dell XPS 8700 desktop going optical out to a Yamaha RX-V365 amp (1/4 inch headphone out). Then going 3.5mm out from the desktop to my SMSL SAP III headphone amp. I tried it through on-board audio directly from my Dell inspiron laptop, then with the SAP III amp in the mix also. I played various files (FLAC, MP3, M4A) at different bit rates using the fubar2000 media player with all EQ off. I purchased my DT 770 used off a professional DJ. They are several years old and have had their fair share of abuse. I will be comparing this headphone with my Sennheiser HD 600 throughout this review. Although the HD 600 is an open back design at double the price, it's useful to compare it as a benchmark.

Design/Comfort (8/10)
A photo or video can’t really portray the quality of the materials used on this headphone. The plastics are thick and have a high quality “thud” when you hit them. The headband is made of solid steel wrapped with a leatherette cushion held on with button clips. A thicker piece of steel is used to suspend the drivers and forms the adjustable portion of the headband. The two steel pieces are held together with a solid piece of plastic fastened with two large screws on either end. The whole assembly attaches securely with screws to the drivers. The overall design is refreshingly simple and incredibly durable. Indeed they do say “Made in Germany” and it shows in the craftsmanship. Given all the steel material it only weighs 9.5oz, a mere 0.3 oz more than the HD 600. Overall I give a clear edge to the DT 770 in materials and craftsmanship.

In terms of styling, it’s clearly function over style with this one. It looks fine, you’re just not going to make any fashion statements with it. The HD 600 does look better on and off the head, hands down. Velour ear pads are simply divine, and these are no exception. Looking more closely I realized the ear pads are actually a vented leatherette material on the backside. You normally wouldn’t see this unless you peel them back. This portion is stitched to the front portion of velour. This design provides improved isolation and bass extension while maintaining optimal comfort. The coiled cable design is not my favorite though, and unfortunately it’s not replaceable. The cable is quite heavy and I just can’t stand having cable tension weighing down on my headphones. My remedy was to tie it to something to give me more slack where I wanted it. I much prefer the light and hugely long cable of the HD 600 which you can simply fold up and tie to your liking. Some like that it’s terminated to one side. This really doesn’t matter to me. I much prefer the HD 600 cable and the fact it’s replaceable is just a bonus.

Minus the cable, all the parts are replaceable on this headphone, just like the HD 600. However, when it comes to durability, the DT 770 takes the cake. Like many others my HD 600 got the cracked headband within months. The best warranty is no warranty issues at all. This DT 770 has had years of abuse and outside of the worn out lettering, you could barely tell. The metal and higher quality plastics contribute to this, but it’s also just a more durable headband design.

I have been an avid open back headphone user because with my glasses and fat head I always had issues with the clasping force on closed headphones. This was not a problem with the DT 770. Clasping force for me is perfect, and the headband support on the top of the head is adequate. The other issue I’ve always had with closed headphones is heat. Within a couple hours I usually start sweating. After several hours of use the DT 770 got warm but never to the point of sweating. Being a heavy, durable full sized headphone of a closed design, this level of comfort is unparalleled. Overall I still consider the HD 600 more comfortable. This is due to the lighter weight, roomier oval ear cups, and even more breathable open design. That being said, the DT 770 is definitely not uncomfortable by any means, and remains the most comfortable closed headphone I have ever used. Overall I give it 8/10 for the annoying cable design and lackluster styling.
Sound (9/10)
Any desktop grade amplifier or amplified sound card will have plenty of power. Onboard audio (unamplified) on laptops or desktops will get loud enough in the 75-100% range. However, bass extension improves significantly when amplified. Even with my $70 SMSL amp I noticed a significant improvement, without the need to ever pass 50% volume. You can get this headphone with lower impedances if needed, but any powered amp will have plenty of power. In terms of power it requires about the same as the HD 600 in my setup.

My first impression of the DT 770 was the improved bass extension. I was expecting this coming from an open design, but the HD 600 is no slouch in the bass department either. Bass manages to stay tight and completely honest. The moment the track calls for deep lows you feel them, but then and only then. I found myself asking “At what cost does this improved bass come?” So I threw some strong female vocals at it. The highs were very crisp, more in your face than the highs of the HD 600, but never harsh, even at unsafe volumes. Because of this, the mids took a bit of a back seat when compared to the mouth-watering mids of the HD 600. Moving on to more complex compositions, separation was outstanding across the spectrum. Sound stage is really great for a closed headphone. Better than my Sennheiser HD 25-1 II. It won’t have your head turning to locate that “noise” in the room like the HD 600 does. However, every instrument and vocal is always separate and it never sounds boxy. This could be in part to the ported design of the drivers. So “At what cost does this improved bass come?” Slightly laid back mids and a smaller sound stage. Overall I give it a fantastic 9/10.
Verdict (9/10)
To be fair the DT 770 is half the price of the HD 600. All things considered you get a better value with the DT 770. Beyerdynamic manages that with superior materials and durability. You do get slightly laid back mids and a smaller sound stage with lackluster styling. However, you're still getting a completely honest representation with superior bass, durability, and isolation, without sacrificing much comfort. If needed the laid back mids can be easily remedied by EQing the highs down a tad. If you need isolation and are not looking for portability this is probably the best headphone money can buy, even at double it's price point. For my purposes I still prefer the open back design, but I still use the DT 770 in cases where I need to work in a noisy environment. I give it a 9/10 due to the cable design and lackluster styling.
As a result of my positive impression of the DT 770 I am itching to get my hands on the open back DT 990. This would be a more interesting comparison to the HD 600. A friend has a pair of 990's I plan to borrow in the next few months. I will post a comment with a link to my DT 990 review when I get to it.
Edit: I have posted my DT 990 review now.

Solid review. I agree on all points. I have HD650s instead of 600s, but my two Beyers (770 and T90) make perfect compliments to them. HD650 probably gets the most head-time, but when I want fun I reach for the 770s, and I use the T90s for real critical listening.
Thanks for reviewing these excellent pair of headphones. I have to say I agree with all your conclusions except for the soundstage. I feel the DT-770's have a larger soundstage than the HD-600's and I have owned both headphones.
But again thanks for for getting the word out on these excellent Headphones.
Got my hands on the DT 990 last week. Had a good week with them, here is the review.
Pros: They are attractive appearing
Cons: Their sound is muffled, dull and boring, in my opinion.
I am really surprised to see so many positive reviews on the DT 770.  To my ears, the sound this headphone renders is muffled.  To my ears they sound as though someone has placed a heavy cloth over the microphones before recording.  That muffled sound distracts from the details heard from the music.  The frequency range is not well balanced on these headphones, in my opinion.  The mid frequency range is too loud compared to the rest.  There isn't enough for my tastes from the high and low frequencies.   This is definitely not a headphone I would use for any type of audio recording analysis.  Their sound is dull and boring, in my opinion. 
Try DT990 PRO 250 Ohm I LOV THEM, but they are open.
I've had these for a few days and I agree that mid range is a bit too loud when compared to the rest.  They sound great though.  What music were you listening to?
Forward, "too loud" midrange on a Beyer???????????????
Now that is weird - I tried the DT990 Pro 250 and everything was great apart from the RECESSED MIDS and the overwhelming bass; the concensus on Beyer DT770,990 and to a lesser extent DT880 is that the midrange is recessed
Pros: Very forward, tons of bass, comfortable & light, sounds very full
Cons: Slow bass decay washes out other frequencies, very close soundstage, fatiguing to listen to for long periods
Though these are by no means perfect headphones, their price and excellent bass make them one of the best headphones you can buy for under $200.
These headphones are very fun to listen to. They give a very forward, full sound that completely immerses you in your music. Bass is deep and boomy, and felt a somewhat uncontrolled compared to other headphones I've owned. Treble sounds fine and there isn't much sibilance. Mids seem to be nice and flat, but can be completely washed out by the bass and treble. These are probably the most closed-sounding headphones I've owned, in that the bass sticks around for too long, recessing the mids. The soundstage is also very small, there is some positional audio, but everything always seems to be right next to your head. All of this is made worse as you turn the volume up. Isolation is fairly good, but I've heard other isolating headphones that don't display this many drawbacks.
While these headphones are great for music, and don't take too much of a hit from bad recordings, they are awful for gaming. Okay, they're fine if you're playing a Telltale game, but start up counter-strike and it's just a big muddy mess. I don't recommend them for gaming. Again, the low frequencies quickly overwhelm everything else, and the lack of depth in the soundstage shows as well. I also don't think these are great headphones for mixing and/or mastering, because they aren't flat at all. These headphones are great and fun for music, but not a whole lot else. They are easily driven by my portable amp, and the construction makes them ideal for wearing them outside the house. The only drawback is that they're kind of large.
These are rock solid headphones. They may not look like it, but these things are very solid. Many of the parts can be easily removed for cleaning. I never have to worry about breaking them. They are also very comfortable. I love the earpads and the headband is very nice as well. The headband can become slightly uncomfortable after a long session, but take a few minutes off and you're good to go again. The cable is a bit heavy but you get used to it after a few hours.
Overall, don't let the cons deter you. For under $200, this is an amazing headphone.
Pros: Good sound stage despite closed design; very detailed; good bass with tight grip; extremely comfortable even when wearing glasses; fair price
Cons: No replacable/plugable cable; require amp; a little low in the mids
I've spent most of my life with open type cans. A year ago, after moving into an apartment, we decided to make some changes which necessitated me to get closed headphones. This way I would not disturb my wife and vice versa, I wouldn't be disturbed by the noise of others.
For various reasons - price being one of them (no more than $200) - I chose the Beyerdynamic DT 770 Pro 250 Ohm.
Audio setup: CD collection ripped to flac -> Gmusicbrowser / ALSA on Linux using a bitperfect configuration -> Asus Xonar Essence STX sound card with integrated headphone amp -> DT770 (using the cards headphone amp output)
The first impression is that they are extremely comfortable to wear, even for someone with glasses. I can sit and enjoy music or movies for hours and hours without the headphones bothering me. These are definitely the most comfortable cans I ever wore. Another bonus of the spacious over-the-ear design is that they always sit properly and don't block high frequencies etc., something I noticed when comparing them to the AKG K 142 HD on-ear headphones which require careful positioning else the highs get blocked.
Soundwise the DT 770 Pro aren't flat - both bass and treble are a little enhanced, and the midrange a little recessed. This usually doesn't bother me, as the headphones are very musical. No matter what I play, the DT 770 reproduce the music, and not just a summary of sounds. Complex passages of classical music are clearly resolved with no effort. The sound stage is quite wide, considering the closed design.
Ella Fitzgerald and Louis Armstrong come alive on Gershwins "Porgy & Bess" recording. Rachelle Ferrell on "First Instrument" is powerful and detailed. Montserrat Caballe's "Puccini Arias" are a joy to listen to.
With modern music the DT 770 are capable of delivering a nice punch in the bass and sweet highs without sounding harsh, even at concert volume levels.
Jazz tracks such as Lew Tabackins "Tenority" are played with authority, so is Miles Davis "Kind of Blue" (the remastered "Gold" CD).
Is the DT 770 Pro perfect? No! It's recessed mids are clearly noticeable. But the DT 770 has a musical signature that makes it worth auditioning.
I'm also using the DT 770 in my home theatre where it's driven by an Audiolab 8000A. The closed design and great audio quality lets me immerse into the movies, without getting on the nerves of my neighbours.
Would I recommend the DT 770 Pro 250 Ohm? For use in a system with a headphone amp - yes!
I couldn't agree more. Just two things: yes, the mids are a bit less noticeable than the rest, a bit 'recessed', with a bit less volume so you won't understand so much about the music that lives there if that music has also a lot of things going up and down in the frequency range... The 'details' are there but you will have to do some extra effort to hear that part of the music, and, sometimes, that task could 'interfere' a bit. Why? because the upper bass and low mids are good. The sort of male chorus voices and certain instruments that lives there. They are portrayed in a very nice way. The enviroment for that sounds to exist is very well controlled. Everything is very very quiet, the music can swing in power and volume effortlessly and nothing could disturb you from the music meaning, presented as a whole thing, even with the not so evenly portrayed high mids and low treble, i.e., female voices and children chorus. Violins and othe instruments with higher pitch... is a different matter. You see, the problem nowadays is the tricks in the mastering process and the 'taste' of the modern public. A lot of music is 'toasted' and, sadly, you will hear clearly all this stuff with the Beyer. It could display complex passages, it could show you the music in a high expressive way but it will also recover some of the nastiness.
the trick: mid-low volume or under-powered amplifier for similar effect. You will lose some details of the music but also all of the nastiness of the recording. Attached directly to a laptop it could render music so beautyfully it could harm. Attached to neutral-high powered amplifiers... and a neutral fine source... you will have to expect some problems and deal with them.
DVD-Audio or SACD with their boombastick spectacular sound, or heavily processed signal... are also very problematic. Expect to be more picky.
For lovers of very expressive music that plays a lot with pianos and fortissimos, for layers of details in distance and volume, this is a good tool. The quiet environment and the easyness for the sounds that live in the range where the structure of the music is are the culprit of the good music the Beyer delivers. Again, certain softiness in the treble from your selection of material to be played are highly recommended. Even if they portrait the treble in a very clear and powerful way it doesn't means they offer the bleached sound, the easy-effortlessly-but-compressed, clear as a swiss lake sound of current trends in audio. They are old style, old brand, old in the market headphones. They don't do tricks or slice the music or render the notes individually in the space for you to feel things that are not music. They respect the music but also deal with the low level signal and every turn in the master recording process. So, choose carefully your program or choose carefully what you want to obtain from them. They will not change for you.
Pros: Wide soundstage, extremely comfortable, blocks out sound, people can't hear your music, very durable, good for all music, best allrounders under 500$
Cons: heavy cord, you will need a good source to get the best out of these.
I am completely re-doing my review on these headphones because I think that these cans deserve it!
I would say that the beyerdynamic dt770 pro 250 ohm are the best closed back headphones under 500$ or even perhaps 1000$ if you have a good enough source to bring out their full potential.  I say this because these headphones offer a true uncolored sound that stays truthful thoughtout the whole frequency response.  Nothing is boosted in any way but these are tuned to deliver a completely flat response with little to no distortion.
Bass : The bass is strong, tight, controlled, and does not get boomy or muddy unless the song itself is not properly recorded.  You will not hear bass this good in a 180$ dollar headphone. The sub bass is the best I've ever heard yet.  It is well extended and very present with a satisfying rumble that can please a basshead.  The quality and quantity are both good and could satisfy anyone.
Mids : Not ressesed at all but the mids are full and lush with a lovely separation of instruments and live sound that gives the music energy and punch.  Also super clear with good resolution and definition that gives you everything in the song.
Highs : a little on the soft and dark side but very smooth and plentiful.  Some might want a warmer sound or even a brighter sound but you will love how easy it is to listen to these cans.
Soundstage : The soundstage is super wide and has amazing instrument separation for a closed back.  These do not sound like it's in your head but the music surrounds you and sounds very realistic.
Comfort : The comfort of these headphones is on par with the hd800s.  Which are some of the most comfortable in the world to date along with the Philips Fidelio x1.
Durability : These are made with metal and high quality plastic that will last a lifetime.
Pros: Every type of music that comes out of these sounds very good. Period. Maybe not perfect, but it performs extremely well regardless.
Cons: Struggles with the very low and very high end of the frequency spectrum at times. Very rarely. Price if not on sale.
If you are like me and listen to a wide variety of music then look no further than the beyerdynamic DT 770 PRO.  God bless the Germans.  Top quality construction and sounds brilliant across a broad range of musical genres.  Great price on Amazon to top it all off.  Couldn't be happier.
Pros: Price - Build Quality - Sound - Customizable
Cons: higher impedance (mid range) needs a decent amp/dac and source
I won mine at an eBay auction, slightly used and all reviews really live up to the fullest except for some over hyped cans which I have also tested before I decided to have this set.
So to presume mine has already burned in, was thinking of making it as my main home rig but I need to find a decent amp to unleash its might wherein my Fiio E17 couldn't contrary to the rave of this combo. I am using it mainly as a gaming headset as I have a very sluggish laptop and it takes a while set this baby up. I use it with my xbox - analog optical audio adapter - optical cable to the fiio e17 and finally this DT Pro 770 Pro and I could say it really has a solid performance, always I am on MW3 multiplayer and I could accurately hear footsteps and help me with better killstreaks.
As for my LAPTOP/PC audio setup I use foobar+asio fiio drivers+e17 and I could say it sounded neutral (punch and sparkle eq setting). I need to have me a decent amp to make a final conclusion. Will definitely recommend to everyone looking for a pro sounding all around over the ear headphones. Will update soon with better details

Pros: Pretty big soundstage for closed back. Tight, punchy bass, nice highs, super comfortable. Good bang for buck.
Cons: Mids are a bit neglected, cable is integrated
I just got my pair, and I can say that it was well worth the money I paid for it. I have a homemade discrete amp to drive them which makes everything sound brilliant. Of course, that's what is needed to drive the 250 Ohm versions but I guess a portable amp will just barely do the trick.
For the price, I would say that these cans are worth the money as they have a pretty astounding soundstage for closed-back after I compared them to a pair of Sennheiser HD 650s that my friend has. In addition, the build quality is superb and it seems that they can withstand a couple of kicks or drops in their lifetime. 
Good if you're a starting audiophile like me, well worth the money in both terms of sound and build quality.
Pros: Very comfy / Overall good sound quality / Nice lows / Price
Cons: No significant cons
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.
The DT770/880/990 Pro are the most comfortable cans i tried, thumbs up!
Try em! It's simple as that...

Pros: Amazing sound stage for closed back, The frequency range on these is very impressive, they have great tight bass, clear mids, and pretty nice highs.
Cons: Integrated cable
I've only had a few hours to burn these in, but so far I am extremely impressed. As of now I have the FiiO E6 amp to drive them, and it pushes them better than I expected. Being that these are 250 Ohm there aren't many portable amps that can do these cans justice. They frequency range is what I'm most impressed with 5Hz-35000Hz. They provide bass if you want it, and it is pretty clean and tight. The mids are very enjoyable, and I believe the highs to be pretty good too. Overall these headphones are great, especially for their value.

Has anyone EVER bought an expensive piece of hi-end gear and admitted that they made a mistake within the first few hours of listening? Of course you're impressed.

^ I just bought a pair of HD 598s and got them Tuesday. I made a mistake.
Thanks for the great review Taylorsethe. I've had mine for about three months and they completely satisfy while giving me decent isolation from my environment. I was surprised at the balanced fullness of the treble and bass with neither overpowering the other. They have a warm sound yet the treble is still detailed probably due to the excellent frequency range of 5hz-35000hz you mentioned. Noticeable soundstage when playing games bordering on a open air headphone. I use the Beyerdynamic DT 770 Pro 250 ohm version with my Onkyo TX-8555 stereo reciever at neutral settings but have noticed they handled full bass settings with no distortion at all when i've accidently had the tone settings at full.
Pros: Too many to list
Cons: Cable
Set up for review:
IPOD Classic 6th gen
Electric Avenue PA2V2 amp
WAV Files only.
Brilliant sound from closed cans for the price
Build Quality is top notch
Sounds great with various genres (Funk, Soul, Jazz, Hip Hop)
Not a fan of the cable. Would prefer a straight cable
Need to know:
These really need an amp for portable use.
What dac/amp would you recommend under 200$?
