Listening to music
I know if you have a full face helmet you can place the speakers behind your ears you not cut your hearing. I have never done this. There are too many radios availible to place on a bike, and specialy desined head sets that allow for outside noise. On a bike you need to be aware.
I pesonally tend to listen to the tunes rambling through my head. My ride time is the time for me to escape all the tippical things that stress me. Music is cool and all, but most walkmans will not pick up stations well enouph to make it realy worth it on a long haul. But then again if I use my brother rase car explanation, if you want music give it a little gas. :lol:
