Need bluetooth headphones for excercise?

I’ve got an LG chocolate with plenty of music on it, and I don’t want to spend more money getting an mp3 player. I run a lot, so I want some bluetooth headphones that won’t fall off when I’m running and will be comfortable for a long time. Doesn’t matter if it has a microphone or not. I’ve checked product reviews, and no one really comments on how well they stay on, so I was wondering if any flutherites had any experience with any :) Thanks
