What are the best headphones for athletic use?
I use either the Philips/Nike over-the-back-of-the-neck earphones or Sony clip-over-the-ear sports earphones. Both are fairly impervious to sweat, allow outside noise to enter (I mostly ride bikes and jog multi-use trails, so this is a plus) and are available for less than twenty bucks (and, in both cases, sound quality is about what you’d expect from anything that costs twenty bucks and doesn’t say Koss on it) Also, there have been about a million AskMe questions about headphones, and looking through them might give you some more ideas.
