I work out much better listening to music (like most people) but I have to wear those over-the-head earphones. They're the only thing that's comfortable. Does anyone else find that their ears are in pain when wearing ear buds for longer than a few minutes? I don't mean pain from music that's too loud, I mean pain in the cartilage. And I've tried a lot of different brands...no difference. Anything that goes in my ear is really, really painful.
