I have an 8GB iPod Touch that has worked flawlessly for the past nine months. I started watching TV shows on it while on the treadmill at the gym when the headphones dropped a channel. The unit is placed on the face of the treadmill with a bit of sticky tack so it is not bouncing, nor is the ear piece jack being pulled. The left channel is completely gone. I took it in and the staff simply replaced it. I got home plugged in my headphones and it seemed the problem was fixed. A day later, no left channel again! I do not use the standard white Apple earbuds. I bought a pretty nice Phillips set and it was the one giving me trouble. I bought another set thinking that maybe it was just fried. A day later, same issue. Here's where it gets really twisted...the white Apple ear buds work fine! I plug the Philips into my laptop and the left channel is gone. The Apples work fine. I am at wit's end. Has anyone else experienced a third party headphone issue with their iPod Touch. I have forked out a hundred box each for the Philips sets and they only play the right channel after being used on my iPod Touch! Help!
