I have a two year old ipod touch (3rd generation a think). Just recently I've noticed that the headphone connection seems to be faulty. At first I thought it was the headphones, but now I think the connection on the ipod has an issue. What happens is I lose the sound in one ear and I have to jiggle the headphone into the port to get it to emit full sound over both right and left. I've tried two different earbuds and the same thing happened. Has anyone experienced this? Is it easy to repair?
