One of the earphones DOESN'T work!

For some reason, one of the earphones on my Ipod touch DOESN'T WORK, and IT'S NOT THE EARPHONES, it's the IPOD TOUCH! I tried like 4 different earphones and I always had the same problem. ONLY the RIGHT earphone works! Do you guys know any way to fix this???

thank you!!!
