Looking for a good set of headsets. I know nothing about them, so let me know what is out there and works good. I'm new to the goldwing. I have a 2001 1800 wing and we have two open face Scropion exo200 helmets. Does the radio work thru the helmet speakers once we are plugged in? What is better, the plug in units or the cordless ones? Thanks for your help.
