About to pull the trigger on a blue tooth head set have narrowed it to three. Scala rider g9 powerset, Scala ride g3 multiset, or the sena smh-10. My only question is regarding the G9. It says that you can connect via Bluetooth to an iPod, then goes on to say that rider and passenger cannot share music. Am I correct in assuming that the rider would be the only one to be able to listen? Seems to me for that kind of money you would. The smh-10 says you can as well as the q3. Just looking for some clarification on that issue. Any help would be great. BTW: what are your favorites?
