I've used earbuds for years (usually Sony) with my iPod. But I just got a new bluetooth headset that is a u-shaped collar of sorts that goes around the back of my neck with earbuds attached. It's going to work perfect with my Droid and my helmet. I can either control it with my Droid on a handlebar mount or directly on the headset rig.
Last year I didn't listen to music once while riding, but I didn't go on any long trips and I was riding a quiet bike.
