Ok, I recall small threads made a while ago about audio when riding and such so I figured to put it all in thread.

Which some poeple like ear plug/headphones for thier music some like speakers and such. Personally I find that if you're riding a bike and wish to listen to music you should only have one plug in the ear and should only be the right ear for obvious reasons as you're mostly on the right side of the road. The left ear should be clear so you can hear traffic and the volume should be low so you can still enjoy the music yet still have some outside hearing of what's around you as well to help increase your awareness of what's around you from the left ear doing al the work.

I myself use a speaker system. It's integrated in the bag. Speaker backpack which allows me to ride while hearing the the news radio for traffic reports and sometimes if/when I have the mp3 player hooked up for newscasts.

I ran into this a few days ago and thought it was interesting. Very San Fran and downtownish but I love the artistic bike side with the speakers loaded up. Speakers on bikes
