I picked up a Q2 for around $300.00 works great for rider to passenger. Has Blue tooth for phones or pairs with other bikers. It also has an MP3 port. If you get a spliter for the Ipod you both have tunes. It's all voice activated. It has FM radio for around town but not much good on the open road.
What kind of helmet are you using and how are the speakers. I have a set of nike speakers in my full face and can barely hear them on the highway. Also, do you find the voice activated part cuts off the first word or two before it kicks in?
Did you pick-up a set? Last night I pulled the trigger on a set of SENA SMH10's from E-BAY. They have been getting high ratings from many forums. Good volume, easy controls, can link upto four sets. Can't wait till they get here.
I am using HJC full face helmets for both me and the wife. With the speakers placed inside the helmet so they touch your ears I have to remind the wife to turn it down, she controls the IPOD and the controls for it are seperate from the Scala head set. As for that first word problem sometimes your have to say hello or yes dear twice. Every once and a while wind coming in under the helmen activates the voice control so be careful what you might be munbling to yourself.. Like the system works great.
We have had extremley good feedback on the new Scala Rider G4 as well. It is completely bluetooth and is full duplex. I have personally used it and found the clarity to be incredible. We recentely did a review of it, see link below.
