I ride all the time. At least ten months/year (I do avoid the snow, mind you). Since I'm always on the bike, I really miss my tunes, so I use the Sena's to connect to my Zumo (directions, phone, and about 1300 songs on the micro-SD card). Crisp, clear sound, and surprisingly decent bass. The mic will only pick up my voice and not nearby traffic, but when traveling in excess of 35mph the wind can overcome your voice (then you drop the visor on your modular helmet and your good up to at least 65mph...haven't tried faster than that of course). Wonderful product!
*NOTICE - I've only received calls on the bike, since that only takes a single push to answer. NEVER try to call someone while you're riding. That's why we have gas stations and the shoulder.
