I'm thinking sena 20 it pairs with any other make and has a long range it's tough to pick as they are getting some good products out now
Just so you are aware, the Sena SMH 10 also now pairs with any other make as well. It just came out of the latest firmware update. I have no issues with this unit whatsoever. One of the things I really like is the choice of various mounting options to suite whatever helmet you have.
