Why doesnt my iPod play music out of both ear phones?
WHEN I PLUG EARPHONES INTO MY I POD MUSIC ONLY COMES OUT OF ONE SIDE OF THE EAR PHONES. wHY IS THAT? WHAT CAN I DO TO FIX IT

answers:

it may be because of you settings, if you go into the settings there is an option for sound controls and you can set it to the right or to the left, if its not that its your headphone jack itself and there is a repair guide on ifixit, just replace it, it is so easy to do.
