No problem to pair my phone detects the fine. The sound is pretty good for a speaker of this size but landed at the maximum level. Crackling noises can be heard and I have to turn down the volume a notch to find a pure sound. Except this false note, I liked the sound rendering. You can also adjust volume from the same enclosure if it remains dependent on the smartphone or tablet (mini volume on it, you will not hear anything). One can also break, move from one beach to another including a micro-SD card as this speaker allows to read them. We present the card upside down (circuit up) and driver from the enclosure. It's not bad but as you say that if you listen to your beach 169th micro-SD, it is not won! The appellate decision worked without concern for me and the music picked up where it left off before the call. However, the FM function does not work for me (no station found). Autonomy, I held 3:30 pushed in test (1h15 max and 2:15 half volume). In normal use, you should hold 5h announced.
In summary, I liked this place in functionality and sound quality but the finish is far from exemplary with this plastic not pleasing to the eye. I most destinerais to children with its original spherical shape especially as it is very bright as the top of the ball flashes blue continuously.
Edit 13/12/14: After contact with the seller about the FM function, he advised me to serve me jack cable as antenna and indeed I capture stations now. FM function works so (without being connected to any device), just remember to put the jack cable.
