Either buy something else or buy the warranty. The right speaker is dead. This is the second pair of DT770s that has had this exact same problem (the right ear speaker is over attenuated and has static, then dies eventually). Apparently there are others out there that have had the same problem. It doesn't matter how good these sound if one day they are broken. Buyer beware!

I am in love with the sound that they produce. When I got the new pair I simply let them play some loud music to a pillow for 100 hours and then listened to them again. It made a big difference! Much better sound. So do not forget to break them in before coming to any conclusions. I listen mostly to classical SACDs, some good quality rock like Radiohead, Nick Cave. Jazz is my next thing. Classic rock sometimes: Pink Floyd, Led Zeppelin. But I would assume that if there is too much bass - it is definitely your CD that is recorded by a weird sound engineer.

Now, the quality is not the same as it was 10 years ago. I used to have an older model and it was built a little bit better. The picture on this website is actually a picture of an that older model. The real thing that you will get is different. Go to the Beyerdynamic website to see it. It is cheaper looking to my opinion. Sound is the same though, and that I like. What is really bugging me is that tiny wire that connects right phone to the left. It is inside of the sleeve and it is can be really close to the moving parts. It can be damaged while you are adjusting the headphones size. These metal parts are sharp and they might actually cut the wire. Make sure that you open the sleeve and re-run the wire as far away from the moving parts as possible. Another thing is the annoying popping sound that they make sometimes when you put them on. Again, these metal pieces inside of the sleeve are rubbing against the metal frame. This problem had always been there even 10 years ago. I used to work at a radio station so I had to put the headphones on and take them off about 100 times per day, so I stopped noticing these clicks. Now I listen in order to get some musical nirvana, so that problem bugs me again. But don't listen to me too much, I am a perfectionist. It is simply impossible to completely satisfy me. Get these headphones if you care about good sound. These are one of the best. I like the fact that they are made in Germany.

I've had these headphones for 6 months now. I love(d) them to death. I babied these as I do with all my equipment. One day in the studio I was listening through a signal processor, plugged the headphones into my computer and my right channel was gone. I spent about a half hour trouble shooting everything in the signal path before checking the headphones. I have an electronics background so I decided to open them up, hoping it was only a bad solder joint or a partial short somewhere. It wasn't, the speaker was the issue. After checking with an oscilloscope I found that it was still reproducing sound, just severely attenuated. These are junk now for anyone who isn't deaf in their right ear. It's a shame because the sound and comfort is incredible. Buy the extended warranty if you still want to buy these. That way when to die on you, you can purchase something else and only be out $20.

This pair is good for mixing but absolutely not for vocal monitoring. It compresses your vocal as if you're singing in a can. It has good isolation. Senheiser hd280 or sony 7506 are much better for vocal monitoring.

When it comes to making an opinion about headphones, I find it best to give it a sufficient amount of playing time so that quality is exposed. Often headphones come out of the box sounding perfect, but "crap-out" after a couple weeks. I've owned these for 3 months now, and have been played through everyday... they are still as amazing as the first day. The bass response is baffling! Because it can reproduce sounds that are bellow the hearing spectrum (<20Hz), you can actually FEEL the bass. Same thing applies to the highs, which gives the listener an "air" feeling. Clarity and a flat response are key in these headphones. They are so clean, I've become a little bit paranoid about the sound! I listen to music with precision, always trying to find discrepancies. With these, I heard things I've never heard on the same tracks before. I would hear a little bit of distortion and ,at first, would blame it on the headphones. I thought to myself that I needed to return them, but I then realized with much testing that, actually, it was the track that had distortion. The mix or mastering engineer must have tried to push it too much. But that's just the thing, I can hear so much more with these that I notice all the bad stuff in professional recordings. I'm always testing these headphones to make sure they're not buzzing on me. Nothing... Simply nothing. Buy these, I guarantee you won't be disappointed. Plus, these have only an 80 ohm impedance, so you can get that clean, precise playback from any musical device. These are worth every penny.
