I received my HD580s last year with a custom built amp. I've been having a lot of issues with the pain in my left ear. The inner part of my ear gets really inflamed. I've been using the beyerdynamic dt770 for the past month and i'm having the problem again. I didn't have this with other lower quality headphones. I should mention that i'm using these to play video games and listen to music. Mostly counter strike 1.6. But even when there is no sound playing, as long as I'm wearing them and they have power coming to them, it causes pain. Anyone had any similar issues. I read somewhere that it's because my ear is sensitive to the frequency since these headphones deliver better frequency then others. If this is true, do I have to keep wearing them for my ears to get used to the frequency? or what? please help. Thanks.
