This is an excellent product. Don't know how we went all those years without it. Stops all noise from passenger and rider mics being transmitted to ears when not wanted. Easy to operate with a flick of the PTT to toggle off or on.
Good to use solo or two-up.
We already had passenger CB controls so pillion can toggle as well.
Flick 'em on to talk then off again for peace and quiet or better quality music without wind noise from the mic.
Uses same controls but does not interfere with CB usage. (Or if you don't have a CB - finally a use for that control box.)
Fitting was easier than I thought. Only had to remove the seat and left fairing pocket. Top cover only needs remove the two rear bolts then gently lift away to pass the wire through. Plenty of room to do this even with my big clumsy mitts.
All plug and play with no hassles.
Thoroughly recommend this product.
