I plugged an AC adapter into my heaphone jack and plugged the other end into an outlet. I was being stupid apparently. After that I plugged the headphones back into it, but all I could hear was static mainly on one side now and the other side is silent while music is playing. ALL my heaphones will not work with the Mp3 player, but they work on my computer so it is NOT the headphones, but the headphone plug on my Mp3 that I somehow messed up when I plugged that AC adapter into it... What do I do? Is there a way to fix this problem I unintentionally created?
