You can buy Sena, OR this for $36, have all the things you want, my friend and I bought it and we are using as intercom and bluetooth, it will stream AD2P (music).
Works with iPhone Siri as well.... it's amazing... look at how many have bought it.. can't stress the fact that bluebooth devices are dead cheap in china, and Sena is charging over 150 bucks for a simple system.
Been using for quite a while now, few times in rain, solid.
