Pros: Great for running.

Cons: Buttons stop working after a few months (sometimes weeks or just days) of heavy use. They also pinch a little bit, but you get used to it.

Overall Review: I've bought several pairs of these headphones. When they work, there's nothing better for running. I don't know if it's sweat, rain, or just heavy use, but they inevitably cr*p out. Sometimes I get almost a year out of them, sometimes just a few months, sometimes just a week. I know I should stop it but I just can't quit these d*mn things. They're less worse than all the alternatives I've tried.
