Mini size but max power

I was surprised at the opening of the box by the small size of the enclosure. Only 6 cm high and 6 cm in diameter!
But the sound power that emerges is not proportional to its size. The sound is rather good or very good, and gives off good!
The call pickup function works perfectly and music resumes when the call is disconnected.
The cursor on / off is under the enclosure while the other function buttons and sockets USB / jack, microphone hole, the wheel sound and a mini SD card slot, are all placed at its base all around.
The anti-slip plastic bonded under the enclosure ensures a good support, it does not slip if it is a bit rushed.
The build quality appears to be top, it's clean and well finished. The brushed aluminum association and shiny plastic is very nice. Pairing is done quickly, without worry.
A top enclosure in a mini format. The USB jack and cables are supplied for charging and the use of non Bluetooth devices.
I have not tested the FM, being geographically misplaced, radio is still a problem for me /
