I have a €30 pair of Sony earphones. When I listen to my iPod using them, the left ear crackles and sometimes Ive to rotate the connector to get sound in the left ear. Dying earphones, right? Except, there's no sign of damage to the earphones, AND they work fine in my PSP, my laptop and my brothers Creative Zen. My brothers earphones, and a spare pair of cheap earphones both work fine. So to summarise: My earphones work fine in every other device. Every other set of earphones work in my iPod. My earphones don't work properly in my iPod. What's to blame here?
