Pros: Fun Bass

Cons: Mids? What mids?

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.


The Beyer DT770 is a ported transducer. The port is a small hole about 5 mm in diameter located directly above the yoke attachment point on the rear of the left phone and on the front of the right phone. The size and length of the port determine the resonant frequency of the air in the cavity ported by the hole. If you insert a length of hollow plastic tubing, about 12 mm in length, into the hole (heat shrink tubing works well; I flared (stretched) the outer end of the tube to keep it from accidently being pushed all the way into the air cavity.), the resonant frequency of the air cavity will be lowered. This will eliminate the one-note "whump" bass and replace it with a more realistic (tighter and deeper) bass response. I experimented with different lengths of tubing. Maybe you can find an even better length to use.
My solution was to get rid of them years ago and get better headphones. Your solution sounds interesting though.
Interesting solution endeed. The DT 770 do have a low frequency resonance. My solution I swtch back and forth between my Grados SR 60s and the DT 770 and i get a new perspective on different types of bass, midrange and soundstage. That helps me.
one note bass? sucked out mids? man you must be listening to something different because the DT770 have great mids (and great overall frequency response and balance). The bass is very defined and smooth, hardly what one might call a 'one note whump'. I've compared these to over half a dozen other similar priced cans and these sound the best of them all by far. Right now it's down to these vs. the Custom One Pro. The C1P are a basshunter's wet dream, but sacrifice a bit of midrange detail and don't have the wide soundstage and presence that the 770 have. I also tried the 880 and found the sound nice and detailed but with hardly any bass response compared to the 770.
Not to beat an old dead horse here, but were they sufficiently burned in?  I know mine changed dramatically, but took a good long time...kinda miss some of the bass on certain tunes.  Besides that, hard to beat the sound for the buck...
These are my first good pair of headphones, and I have to say I can strongly agree with the bass emphasis. When I bought them I didn't notice, but after quite a few hours of break in I've noticed they've become quite bassy. Right now I'm listening to Hotel California and Randy Meisners bass is really taking the show. I'd like to say I've given these around 70-80 hours of use with music, movies, videos, and gaming, so I expect them to get a bit more broken in, but I will more than likely be turning the bass down on equalizer by the end. Great review, and a great pair of headphones nonetheless!
