I just got a new pair of headphones after my old ones broke about a month ago. I get home, plug them into my ipod and they sound great, except for this faint distortion that especially comes through on drum fills and low bass notes. I tried turning the output volume down and it's still there, so it's not the headphone speakers suffereing from overexcursion. I plug them into my computer or my friends iPhone and they sound wonderful at all volumes/styles of songs, no problem. Is there anything I can do to fix this problem? It's really bugging me as the clarity of the music is just not there, and I dont have the money to drop for a new ipod right now.
