Beyerdynamic DT 770 Pro-80 Closed Studio Headphones

This was my first pair of what I call real headphones, Loved them the moment I put these on my ears.
To me they have a massive soundstage (quite odd considering they are closed), big bass, and extremely comfortable. I would recommend these to anyone looking for a headphone to use with any type of electronic music. They can be powered from an iPod but sound much better with a dedicated headphone amp. The headphone amp brings a certain "energy" to these headphones that makes them really wake up. Make sure that your headphone amp if using one has a lower output impedance (less than 1 ohm) for best results on these.

Build
Featuring a simple design, which what looks to be only a few parts, each part is made out of high quality rigid materials that together feel as though these headphones will last a very long time. The headband strap is plether and attached by wrapping around the band and connecting with button clips. The band itself is a very flexible steel substance and offers good tension. I suppose if some find the clamping too tight, it could simply be stretched to reduce pressure.
 
Comfort
With each headphone enclosure being mostly plastic, and the band being quite a thin and light substance, the overall weight of these headphones is fairly negligible considering they are very much a full sized circumaural headphone. I do find after a while my neck tends to lightly cramp, though I suppose this depends per person. Ear cups are not valour but are still very soft and comfortable. I find occasionally they can become a bit itchy (especially with facial hair or in hot climates) but in almost every case this isn't noticeable. The headphone cable is on the left earcup and is not removable, which can be frustrating depending on the placement of your amplifier or source.
 
Sound
I would say the Beyerdynamic DT 770 PRO offers a fairly dark sound with an incredible bass response. Each bass note booms giving somewhat an emphasised sound, though not over the top, but it could be a loose for some tastes. I find the sound is fantastic when paired with electronic, rock, hip-hop, or otherwise powerful or loud music. Unfortunately, depending on the type of sound, often highs will appear insignificant in their representation, and occasionally sibilance is noticed over the smooth sounding bass. Though, considering their price, I would say these are a fantastic entry-level audiophile headphone - they are built and designed for home use, sound fantastic when amplified, and offer a special sound at an affordable price.

Good Quality much better than my previous sad to say I have Dre. Beats.... Embarrassed to even say I had them but nonetheless great headphones great highs great mids and great lows (in my opinion) so ya good starter audiophile headphones I would say

Build - 
 
These are very high quality feeling headphones. The metal headband clamps enough for a decent seal, but not enough to make them uncomfortable at all. The metal attaching the cups to the headband is very rigid, and the plastic cups feel super solid. No complaints about the cable either. No fear of these breaking any time soon.
 
The isolation is quite good. They have trouble blocking out low bassy sounds, like a bus engine for example, but I think that's a common problem in most closed headphones. 
 
Comfort -
 
Easily the most comfortable headphone I've ever worn, by far. I wear these for 6+ hours per day with no issues. The padded headband, the plush velour pads, the perfect clamping force, they're like having pillows on your ears.
 
Sound -
 
The bass extends very far, and the impact is incredible. Pretty similar to the ATH-M50s bass. Songs like Ratatat's "Eight" sound amazing on these.
 
The mids are a tad recessed, but full sounding, and very detailed. Not much else to say about them.
 
The highs are present, but rolled off and put a bit in the background on many tracks, in my opinion. They lack the sparkle and detail of something like a Shure SRH940. I EQ'd mine up by about 4db at ~3-6KHz and 14KHz which gives them a bit lighter feeling.
 
The soundstage is decent for a closed can at this price range, but I find that, especially with symphonic metal, they lack the depth and layering required and everything gets mushed together. Quite accurate though, which makes these a good can for FPS gaming. Very easy to tell what direction things are coming from.
 
 
Conclusion -
 
An excellent headphone, especially for electronica, but sounds good in almost every genre (I'd say every genre but I don't listen to them all). Definitely worth the ~$200 street price.

I had the akg k412 p before them. I love my new dt770. You can wear them for 6 hours and not even recognize them. They isolate extremely well, have great bass and a good over-all sound. I think they are the best headphones in this price range.

I bought my DT-770s about three years ago used (I call it pre-broke in). They produce a great amount of bass and are perfectly sweetened.  The only reason these wouldnt sound good is if you were listening to low quality music, because they reproduce sound very well. Not only that but ive dropped these, thrown em across the room and the like, and theyve held through it all, VERY durable. Great beginner headphones, and the leather pads allow them to be worn for hours. There have been times when im not even listening to music and I put them on anyway

I'm still burning them in so I'll give you a longer review after 100hrs.
 
GET THEM!!
 
 

I'll preface my review with that I am not a seasoned audiophile, so I don't know all of the jargon, but I do appreciate good sound, and I like what I hear in these.   They are by far the best sounding headphones I have ever listened to.
 
Granted my collection of headphones is very limited.
 
I was looking for a closed circumaural design, primarily because I find circumaural cans to be the most comfortable, and I like the isolating effect of closed designs (less sound out to annoy others, less noise in to annoy me).

These headphones work very well in that regard.  I have occasionally even flown with them. Who needs active noise canceling, when these work as well as they do?  Though while flying, a portable dedicated headphone amp definitely helps.
 
The biggest negative with these is the break-in.  I almost returned the headphones when I first got them as I found the highs PAINFUL and piercing.  at first break-in didn't seem to help, but as a "hail Mary" I left them on for a couple of weeks playing music I enjoy and it did the trick.
 
These headphones are not neutral monitors for sure.  at the same time, I feel like their reputation for being overly bassy is a little undeserved.  often when listening to music I feel like using an equalizer to up the bass a bit.   That being said, I listen to a lot of 80s stuff where the bass isn't very prominent in the mix.
 
Overall, I feel like I got a set of great sounding headphones for a relatively low price.  I am happy with them.
 
If I knew what I know now when buying them, I may have opted for the 250ohm versions though.

I purchased this headphone after I returned the Sennheiser HD 25-1 II.
I was not satisfied with the soundstage of the sennheiser, plus after an hour of wearing them my ears started to feel bruised.
 
The DT770 Pro does not have these downsides, the only downside is the siblance.
In a song with a lot of S's or maybe hard t's the headphone starts to whistle. If the volume is cranked up it the whistle actually hurts my ears. Strangely enough this is not the case with all songs that have a lot of s's. Maybe it is not al the fault of the headphones, maybe the vocals are badly recorded, the singer could have used to much ssssss or the song wasn't mastered right.
I have a pair of mackie studio monitors and songs with too much S's sound slightly uncomfortable on these, but when I listen to that song through the headphones it's worse.
 
Use: I wear these headphones when I play the drums, because of the isolation the drums are much less harsh (it is placed in a very small room) and I don't have to crank up the volume too much.
Ofcourse I also use it for listening to music or any application with sound when I don't want to disturb my girlfriend.
 
The sound quality: Is good, it does have a lot of bass, but not too much and it is tight. I like the mids, and the highs are crisp but sometimes a bit harsh (siblance). The harshness of highs is something that is very common in closed headphones, probably because all of the sound is directed into the ear.
The soundstage is very wide, and has a lot of detail making it easy to hear different sounds/instruments.
 
Verdict: Probably one of the best headphones if not the best in that price range.
 
 
 

The DT770 is a lower priced model of the Beyer line, but it is a boiled down version of the Beyer sound and one of the best values in closed headphones. While known for excellent bass response generally, you will also find them one of the most comfortable in the price range. The ear cups aren't as nice as the DT990 velour pads but they are comfortable. They do get sort of hot after wearing them for a long time. One other great thing about these headphones is how easy they are to drive. They drive well on every mobile mp3 player I tried as well as straight out of a sound card. For hip-hop, electronic, or movies I think this is one of the best headphones you can get for the price.
 
 
You may read about is the recessed mid-levels on this headphone. This is true, which is why this is not an excellent pick for rich instrumental or voice detail. Additionally, there can be some sort of irritating siblance going on at high frequencies, but this occurs with all closed-can headphones as far as I know to varying degrees.

Tonal accuracy is very good. I am using as a reference my home theater with Sunfire XT ribbon hybrids and Bag End professional mastering subwoofers. The all important mid-high region is spot on. Bass is slightly emphasized, true, but the degree is exaggerated IMO.
 
Transients are very good, bordering on excellent.
 
Imaging is very good, bordering on excellent. Bettered by semi-open and open headphones, but they have their own drawbacks.
 
Comfort is very good - one can adjust the spring tension to one's preference - very nice feature.
 
Isolation is Good to Very Good - a bit above mid-pack. I haven't seen a variation in this aspect amongst closed backs, excluding super high isolation special purpose cans.
 
Main drawback is load/efficiency. In my experience these can not be adequately be driven by either a laptop sound card or by an MP3 player, even the powerhouse Cowon D2. I have a Turtle Beach USB DAC/amp at work, and a Total Airhead for travel. Without amplification, sound suffers substantially.
 
Note that if you are listening to these without a few hundred hours use on the phones, you aren't getting the full sound quality. Over time, I found that the bass became less prominent, mids/highs smoother, and imaging improved substantially. These phones have one of the longest break-in periods of any audio product I have ever owned.
 
I can and do listen to these all day long at work and on the plane. Very non-fatiguing, highly recommended.

I find the DT700 pro/80 are a pretty reasonable can to start off with if you are looking for something that is good for rock.  The 770 are fun and, while the midbass can be too much for some forms of music, I don't generally have problems with it.  There is some sibilance in some songs, but not generally enough to greatly detract from the music.  The clamping pressure may be too much for some people, but is good for people who like to move (drummers).  Isolation is more than adequate for most situations, although they aren't all that portable.  The 770 do their best with rock IMO, the recessed mids are less audible there.  In the same situation, I would likely buy these again. 
 
These cans can also be used as a hammer in a pinch. 

A bass lover's phone for sure.  Can be fun with the right music.  But the bass is of the one-note "whump" variety and that gets boring.  Still, can be good with rock.  I've noticed some pretty sucked out mids, though, so vocals suffer.  And for a bass-head phone, the highs can get pretty brittle.  Not at all a balanced presentation, but that doesn't mean it can't be fun.  Everyone should give these a try.  And they're built like a tank.

These headphones are my first pair of high-end (probably mid-fi to some) cans and after a year or two of use, I have mixed feelings about them. When I first got them, of course they were a HUGE step up and I loved the bass from them, they were the perfect headphones to me. I was hearing sounds I had never heard before in music, hearing imperfections and low-quality sounds as well. However, one thing I've learned on this site and in time with various equipment, terms like "quality" are largely based upon a users' prior experience with other products. I went from some really terrible $20 and $30 over the ear headphones that were just "ok". The jump to these cans was tremendous.
 
However, after learning more and being able to nit-pick "quality", I think there's quite a bit of room for improvement. A few things in this area would be sibilance (I think it's called) where the higher sss sounds, sound like they were encoded at 64kbps or something. While this isn't hugely noticeable, it can get annoying if you really listen for it. Another thing would be driver distortion, sometimes the driver can get contaminates on it which can ruin the lower frequencies. From reviews and posts though, there almost seems to be a defect in some drivers where no matter how much people clean, it never goes away. I find that usually, for me, cleaning does help. Typically some low-strength tape works such as painters tape, getting around the black foam and whatnot.
 
While there are those downsides, I still fully enjoy these cans. I'm happy with what I paid and how much use I've gotten out of them and will still continue to get out of them. I don't know that I would recommend them to a mid-fi user but someone that is just beginning to get into quality audio and likes gaming or movies, this is an excellent pair of headphones. There are also plenty of mods to these cans to help improve the quality and if you really like the style but want something better, there's the DT880 or DT990 models that are more expensive but you do get more.
