On my DT 770 Pro 80ohms, when there is a lot of bass in the sound I hear crackling on the left side. This happens when there is a lot of bass and never occurs on the right side. What would be the cause of this?

I am looking for some good headphones for my PC. I play games mostly and listen to some rock, techno, and some other stuff. I would like some closed headphones that I can use unamped so I can directly plug them into my soundcard. Around $150 would be nice. Thanks a bunch.

Would the CrossRoads MylarOne X3 produce pretty good sound in a samsung k3. I know they don't draw a lot of power, I just want to make sure I am not bottlenecking good sound quality with that MP3 Player. I ordered the player and have heard nothing but good things about the CrossRoads MylarOne X3...
