It is always advised that you to never wear headphones while riding your bike. Doing so cuts out all of the outside noises which is extremely unsafe while riding around busy city streets. In fact here in Sarasota it is illegal to wear headphones while driving, not sure about biking but it may as well be. The Portable Speaker Design for Cycles is great because it is a speaker that attaches to the handle bars of your bike to provide you with a bit of music while allowing you to still be safe listening to the sounds that you are surrounded by. The controls are basically at your fingertips as well which makes it very easy to switch a song or change the volume without any difficulty at all.
