Hello: My wife and I had a great ride (2013 Cross Country Tour) yesterday south on S.R. 135 down through southern Indiana. She is tired of trying to communicate with me through our fullface helmets. Any couples or groups use sena or cardo bluetooth systems, or similar ? Do they work well when you are in close quarters, like riding two-up ? Could we talk to each other, as well as others in our group ? Hard wired or wireless ? Going to do some reaserch, but I have always had good luck with this group when needing info.
