I bought two sets. The first set had a problem with one of the earphones. After trying all kinds of tricks and tweaks on my iPod to make them work, I've decided it is not worth returning them. So, after much research, ordered another. This pair sounds fine. The problems are they fall out too easily from time to time. Sometimes when I have some weight in one ear, other times not. They also seem very thin and cheap. Not a whole lot here at $20 per pair.
