Query: Good but..

This is a wonderful design for your ear, clean sound / snug fit....but the quality seems to be less than desirable; they keep failing, after just a few months. I think the wire is too thin if you wind it up and put it in your pocket too many times it develops a short and starts to cut out. Too bad i love how it works when it works.
