I have the Creative EP-630 noise isolation earbuds, very high quality and very good sound. Just over the weekend I was listening to my iPod when I noticed that the left gets 100% volume while the right only gets about 70%. I have been messing around with other songs, other devices and it's definitely coming from the headphones. I like to workout with these headphones but I take care of them pretty good and don't drop them, scratch them, etc. The only thing that might of caused this could be wither sweat or a little bit of water. Is there any way these can be fixed (magnetized back?) or repaired? Thanks for your help guys.
