Well, I've got my Sony EX-81's packed up to ship back for circuit city's replacement plan since the wire insulation separated from the headphone unit (as I expected from reading other's experiences). CC is supposed to send me a store credit for the original purchase price that can be used toward a replacement pair or any other pair of headphones. So, can anyone point me toward something else to try? I never minded the sound of the Sony units, but I couldn't get the left one to fit quite right no matter which fit piece I had on them. I've also tried the apple in-ear units which didn't fit at all as well as the normal ones that come with the ipod. I'm considering a pair of Shure E2c's, but wanted to see if there were any other possibilities worth considering. I want in-ear buds rather than something bulkier.
