Hi - I bought a Scarla Rider G4 so that I can play music from my iPhone via bluetooth and answer calls etc., for which is works just fine. My old lady doesn't ride so don't know about the intercom side so can't comment on the mile claim (US or UK)!

 

My father and I own the g-4 headsets. We have synced up four headsets on the road. The bluetooth works good from my andriod phone. Pandoria is nice on long trips. the fm is limited on range but does work. It does take a bit of learning on your part to operate the headsets. The manual does explin it, but work with it before you go riding. The mile range is nice.

 

Got the Q2. My wife is just learning to ride and it makes things a bit easier for me when I talk to her while riding. Ride an EG so don't nedd it for music. The phone works good. Picked the set up for just over $200 back in Nov. JC Motors has the set for $243. Cli-Max has them for $199 cli-maxridinggear.com.
