I've had two pairs of them Mike and although they sound great, and not expensive at all..... after continued use and I'm not talking about jogging etc, the rubber around where the ear piece joins the wire is really soft. Therefore eventually it frays!
Common fault it seems, although not sure if newer pairs have the same issue. That said, worth the risk for the money.....
Also with regards to the wire, they come with a two piece.... the standard wire is quite short and is one sided, therefore longer than the other and a loop goes around to other ear. There is an extender wire with it, but for my tastes it makes it a little too long!
I bought some Sennheiser ones last time, but not used them yet ...... but they make cracking earphones. Think some of the Shure in ear ones are meant to be the best.... but you will pay for it!
