Even by car, the corresponding clearly heard our voice without being disturbed by engine noise! In addition, possibility of 2 phones over the same time. Another practical thing, once the device once recognized, it will still be recognized and directly after switching on the unit provided the Bluetooth phone is enabled! More hesitation to have, you will not be disappointed by this product!
