Beyerdynamic DT 770 Pro-80 Closed Studio Headphones

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.

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 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!!
