My friend Devon just gave me half of one of these sets to try out. Initially I will test it alone with my Droid and Ipod, and next time the weather is decent we'll try them riding together (he rides a V-star and will likely be riding to SWTF and the Kootenay Raid with me). He seems to think it works brilliantly with phones and MP3 players.
