I sent my SM3 to EarSonics asking for repair, because I realised that bass from the right earpiece is louder then the left. EarSonics confirmed that there is some problem on the left earpiece and they are going to solve them. I know another head-fier who had this problem as well. So, in my opinion you might want to mail EarSonics to tell them your problem.
