Quote: Welp, I discovered the problem. Turns out, I'm an idiot. It was a bent audio extension cable the whole time. I tried it on a bunch of different sources, just not with different cables.   When I plugged straight in they sounded good as new. Now I just need a new cable. 

Quote: Do you have any idea what I did wrong? I really don't think I ever turned the volume up past a good hearing level. I can't figure out why I would have blown them. Im listening out of a yamaha HTR 5830 receiver and I've never had the volume above -15db.

Quote: i had them hooked up an receiver. This "thud" is exactly what I am hearing. Kinda of pffft, pffft, instead of a boom. I guess I'll go ahead and contact Berer and see about a replacement if possible.

I put on my DT 990's when I got home tonight and they sound horrible all of a sudden. I have no idea what's wrong. I checked my receiver, sounds card, etc, everything appears to be functioning normally. I was EQ'ing my headphones last night at some pretty high volumes and got the bass up way too...

Optical out from both

Quote: my thoughts exactly. Head-fi can be a dangerous place. 

Quote: I've tried them with three different sources with the same results. I lent them to my buddy who is a producer and mixes studio recordings and he said the treble frequencies were off. He showed me how to eq them down, and it does sound much better, but I'm going to shop around for a...

Quote: Yes, I did and still am considering the Senn's. Someone had a pair of 555's on craiglist for $80 and I put a post up comparing to the Berer's and most people recommended the Berer's. I might pick them up and try them if the has them still. 

Quote:   I'm honestly so unhappy with the 990's I'm going to avoid Berer altogether. 

Quote:   I was in your exact situation. I have the Xonar DG sound card. It's good, and the dolby headphone is a neat gimmick, but plain old stereo sounds better out of high end headphones. I ended up getting a cheap receiver of craiglist. Outputs up to 480ohms through headphone out and...

for what it's worth, I just bought the DT 990's 250ohm last week and I am not enjoying them that much. The highs are way to piercing, especially in games and movies. I'm returning tomorrow and now shopping for a replacement. 

Quote: cool, thanks for the info. I'll look up some modding stuff and also try on another receiver just to make sure it's not. the problem.

Quote: Bass isn't crucial. I mean, I like bass, but I don't want to to be the first selling point. Overall quality is the most important. No gimmicks, no great at this, terrible at this, Just balance  across all spectrums. I use the phones 4 hours a day, minimum, watching TV, listening to...

Quote: I did the best I could. Feel free to peruse my post and see all the long standing members of this forum who recommended them highly. Did you want to maybe recommend anything?

I bought the Bererdynamic DT 990's 250ohm of Amazon last week and i've been using them a few days.  After using them for a mix of music, movies and games, the one thing that stands out the most is the piercing highs. I've read some reports on this here and there, but nothing that seemed to be as...
