The connection is child (we search the bluetooth module, and connects to, that's all), the sound is very good. We lose some momentum compared to the output jack (on Blackberry Q10) but the difference is very slight. Note still not a classic neutral equalizer at Sony, a very warm sound with low survey spectrum, but without excess. Even after having reconnected, the connection is made automatically to the phone, or when it is in range. During calls, the sound does not pass on the speakers but remains on the phone.
