I just picked up a pair of these, and they're awesome except for this noise that I can hear when I'm not playing any sound through them (but are still plugged into my computer).
As I begin to plug the jack in, the sound is pretty loud and noticeable, and it quiets down once it's completely in. However, I can usually still hear it very quietly when nothing else is playing. I'm not sure how big a deal this is, but it's getting to me. I can best describe the sound as what you hear (used to hear?) when your cell phone rang near your computer/printer, but more screechy.
Is this normal? Anyway to fix it? I didn't notice it with my old headphones.
