I have CARDO Scala Rider Q2
It is set so I can talk to my daughter, talk to another rider, listen to radio, attach I-pod, and answer calls when I really want to. When you talk it picks it up so you would have to go to just thinking how well the other drivers are doing.It is all Bluetooth, except I-pod. 160$ a headset. ( I got the I am cute and bought a couple other item discount - I think regular price was 200$)
You can also get one that does same thing except talk to and another rider, comes with two headsets about the same price.
