Bought and installed UClear boomless bluetooth intercom in my/my wifes helmets. Very ingenius technology and great not having a boom mic to deal with. Installation was a snap and everything works very well......except... there is not enough volume when wearing foam earplugs which I always do. Testing was done in my living room. UClear supposedly adjusts volume to ambient noise level so I am hoping (but doubting) that they will work when we are actually on the bike. I doubt that the volume can increase above maximum which is what they are at now. Will keep you posted. If one does not wear earplugs, this is a great cordless, boomless system. Damn!
