Because one of the worst problems with the headphones is that you can't hear what's going on around you. If you're sharing the bike path, and someone's coming up from behind you and wanting to pass, and they're shouting that they're passing, how can you hear it? And what happens if you don't hear it and you decide to make that left hand turn, and you get into an accident? Or if your path crosses an intersection with cars, and you can't hear cars coming in the opposite direction. Etc, etc. etc.

I don't know how many near-accidents I've been in just because the other person was wearing headphones. I'd much rather have to deal with hearing someone's music then get into yet another near accident with some idiot wearing headphones that I have to scream obscenities at them... again.
