I thought I had found the ideal: a Bose headset wireless. Too bad there was not the same with noise reduction (tjrs with a son) The audio quality is not as good as with Bluetooth cord (included with purchase) The collision with a wayward Bluetooth Wiko. The same Wiko has no problem to accord with the Bluetooth of my car But Bluetooth module melted during a refill from a PC, two years after the completion guarantee (damage). Would t -it was guaranteed a refill outside its original charger? I do not think so. I do not find to buy the Bluetooth module without the helmet, so here I am with a corded headset for the price of a Bluetooth headset.
