For pairing, it is classic, it is done quite easily. You press the on / off button, the LED flashes blue, you pair following the procedure in the manual and it works.
Importantly: I tested the suction cup. The enclosure holds well on tiles or glass. So it's a good point. Once wetted sucker, she holds firmly in place: no problem. I tried to take off by forcing it lightly, she resisted. This means that your speaker will not fall at your feet or water. And good because the speaker is not 100% waterproof in the sense that she does not work if it falls into water. It is protected against splashes and moisture. That's it. Everything is well described in the insert.
For the drops, it's perfect: they slide on the enclosure that continues to stream music. That makes me the same effect as water pearl on a waterproof fabric. Sealing checked!
And do not worry, it's clever, while the suction cup holds well, simply lift the little cap that extends beyond the cup and falls off by itself.
The sound is okay for a small speaker and I confess that I did not ask more for a speaker that can put music on your phone or mp3 player in your bathroom. And although I still was pleasantly surprised. I think it is rather good and low level. The volume is also correct. This part is subjective but I find it really nice.
For loading, the enclosure comes with a USB> jack cable. This is a classic computer is charging either with a dedicated charger. When charging, the red LED lights. Blue is loaded. And be careful out back the silicone cover protecting the charging port. I did not hesitate to push it a little because it does not take well to prevent the water rushes into and your speaker is rendered off
