25 mi Urban Commute on 5 lane very busy roads.

I wear a radio since my mp3 player broke. I find that the wind noise plus all the traffic stuff going on is just a mash of noise until someone gets really close anyway. I use my rearview mirror a lot and find it much more useful than my ears. I can't hear overtaking cyclists in all that noise anyway so that is a non-issue for me. As for legal or not, how many of you have a rear reflector in addition to your rear light? The law requires one in most states but I have never seen or heard of someone getting a ticket specifically for that when they had a blinkie on that back. I highly doubt that the headphone law is enforced much either. I mean you see inline skaters using headphones all the time, what is so different about a cyclist using them? Anyway, I find the music gives stimulus to my mind that helps me stay alert over long rides so I think that outweighs the negatives for me. I can still hear cars overtake me just as well as before as I don't blast the volume. I think this is just one of those common senses things. They can't tell how loud you have it turned up so they just outlaw it. Figures.
