I have just sent this back after having the exact same problems as i did with my first genration ipod - after light use the earphone controls have stopped working. I had both only a few months. I only had to charge them up a few times in the months i had them but then again i use them pretty lightly. The pattern for both was the same the lower volume stops working then it fully stops working then it completley stops working. After looking around forums and reviews it seems this only seems to happen when sweat is running down the wire to the controls unlike other people mine never did dry out and never worked again.

I bought it for going cycling and even though it isn't marketed for this i still think it should have some versatility the earphones didnt come out like many others have mentioned. If it didnt pack up after a few uses i would really recommend this product.
