Does this happen to anyone else? I'm running with my latest generation ipod shuffle (the really really small one that talks to you) and after a few miles, the volume gets very very very loud? Also, you can't turn the volume down? At all? This has happened several times getting louder and once getting softer. Every time it can't be adjusted until a couple hours later. I'm using the Apple In-ear buds. I'm sure it has something to do with my sweat. Can I return these? This pretty much makes the phones - and the shuffle - unusable. I can't run with the ones that came with the shuffle, since they always fall out of my ears. Anyone else have this problem? Thanks!
