been using the Harley or IMC units for 59,000 miles with my wife. flawless. don't have to charge them. We have had many 16 hour days no worries about batteries

 

I just purchased the Scala rider Q2 Multiset Pro from a forum member. I was looking to use them for rider to passenger communication. The wife wasn't really into them but when we tried them out on the bike she loves them. We both wear 1/2 helmets so I purchased the half helmet kit. And they both work spot on. No wind noise or anything. No problem hearing the passenger and the VOX is right on.
