Hi Everyone! I've been lurking on this forum & others trying to learn about macs & ipods b4 i got them, which I finally did. I just got a 20G iPod and I managed to get all of my music on it just fine. However, the sound on the ear phones is horrible. The right ear sounds fine, but on the left ear bud I can hear noises & crackling & what I think is the hard drive spinning. I can hear the song on the left ear bud, but it's very low & overpowered by these other noises. Does someone know how I can fix this is or should I just exchange my iPod? Please let me know if you have an idea of why I might be experiencing this. Thanks much in advance!!!
