Headphones for the Treadmill

I need a good pair of headphones for running on the treadmill. My pair now is ok, but just doesn't seem comfortable, and the sound quality isn't that great. I'm looking for the best quality sound I can get for under $100. Also, I prefer the clip style over the earbud.

Can anyone who runs, lifts, or does any type of workouts give advice?

Thanks in advance guys
