This FlexSmart X2 is simply stunning. First tested Bluetooth, the equipment is done without any problems (tested with an iPhone 5C and a Samsung tablet - the Galaxy Note 8 - for Android). The sound quality is very compelling, it gives an FM side, as if you were listening to a radio station lambda except that for once, you make your own music selection: p. The scan for unused frequency is done very quickly.
Whether used for listening to music, make calls or GPS smartphone with everything goes smoothly.
I highly recommend.
