I have a pair of barely used E3c's that I lost the ear slips for. It was used for a period of about three days. It is in perfect working condition with absolutely no flaws or deficits. The color is grey. I'm not going to bother buying more slips for it because I just ordered an E5c in place of it. =) Asking $65. Please email me at haominpan@gmail.com if interested! Thanks! =)
