Very good product in 2947

The communication is very good, both for the intercom phone. BT Audio is nickel, or even care when you put the phone I already had cut its concerns or disconnections following the pocket or I put the phone (inside pocket of the jacket, pants pocket ... )

The sharing of music between devices works fine.

The only weak point in my opinion is the severe lack of bass in the headphones when listening to music, however it does not interfere at all in phone or intercom communication.

The wheel is very convenient, no button to search for the different functions, except to pick up the phone.

I have not been able to test the scope as currently madame is with me on the bike ;-), I would try to think to update my review when it is on motorbike.

Fairly good autonomy.
