I do most of my running outdoors. The running "experts" don't recommend wearing headphones at all (but what do they know?

) and I don't like wearing the in-ear hands-free piece of my cell phone, so I don't think in-ear is for me. Soooooo, I guess I'm going to take a closer look at the koss. Nobody mentioned the Sennheisers I was interested in... Thanks everybody for your words of wisdom. I'll let you know my thoughts after I get them.
