The wife have and are happy with the Sena units. We can talk bike to bike in real world situations for about 1/4 mile or so. We each have music, she uses a bluetooth adapter (dongle) and I use the included input wire. We also each sync to our phones as well as each other's units (of course) for intercom. The only nit to pick for us is a slight but noticeable delay in the mic's opening the VOX session, after that it's full duplex, clear conversations at any reasonable speed. By the way, I wear earplugs and have no problems with volume.
