I was listening to my iPod touch (1st gen, 16GB) yesterday when suddenly, the headphones stopped working in one ear. I twisted the cord around a bit, until I finally got hold of the sound in both ears (I had to push the headphones tightly to achieve this), only to lose it just as quickly. I tried replacing my headphones for several others, only to meet the same problem once more. What is going on? I've restored the iPod, but nothing ... thus, I am currently listening to music exclusively from the right headphone. Help?
