Closed-back headphones are rare in the serious hi-fi world. On the whole, it seems, those listening in private prefer not to be cut off from the outside world. And besides, closed-back cans have a reputation for a more 'boxed-in' sound than the open-back variety.

Bass is admirably strong

There can be traces of the midrange coloration

I bought these shortly after my Sennheiser 280 Pro's started cracking near the headband. They still work, but I'll keep them as my backup's. The Beyerdynamics include a completely different design than the more portable Sennheisers, but that's not really a bad thing.

Quality; sound; great brand name; unique style

Maybe too bassy for some; but not me

The DT 770s are another set of headphones in Beyerdynamic's MANUFAKTUR line. The MANUFAKTUR service allows users to create customized color schemes as well as fine-tune other aspects of their headphones.

Beyerdynamic has been known to produce some of the best headphones and microphones ever created for all types of professional uses. Their products range from Broadcast TV, to Hearing Aids, to Pilots, and also to DJ's.

The 770's got re-spec'd (check the Beyerdynamic site, they are quite clear about it) so old reviews, or references to older stock in newer reviews can be misleading. The newer model seems less robust, less durable, and is definetly +8 db at 100 Hz, so the bass is fat.

The first thing to point out here is that the DT770s are a closed-back design. This means sound doesn't escape through the outside of each earphone – so you won't annoy your neighbour on the train the way you would with a noisier, open-backed design.

Closed-back design; powerful sound; very comfortable

Rivals offer more insight; detail and overall resolution

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.

Fun Bass

Mids? What mids

I am very pleased with the quality of these headphones, they give very good insulation in both live studio and FOH work, they are very comfortable I have used them for several three hour periods during band rehearsals whilst mixing multi track takes and also for one and ahalf hour sessions for

I am very happy with these headphones so far! I have cleaer sound from high to low and extra bass for electric drum set bass, is NOT an issue. With other headphones I did have some trouble seinheisser and NADY were, for the model I had not enough volume or range. Nady qh360 and Seinheisser HD210.
