Regarding pairing, already, it is simply done. You turn on the speaker by pressing the on / off button, just look for the enclosure in the Bluetooth section of the phone or mp3 player, simply select the name of the enclosure and that's it, the pairing is completed. Only a small beep tells you that everything works and everything is good. All this has taken just 30 seconds lap top.
The enclosure comes with a jack cable that I have not in the utility, it may serve those with mp3 player is not bluetooth.
The Appeals decision with the dedicated button works well. The microphone works well. Callers hear me well if you stay at a reasonable distance from the device, I would say about 1m. And pressing and holding the play button and good, the call is rejected.
You also have a button which allows you to pause the music. The volume buttons (+ and -) are appreciable because they also allow to go back or move to the next track.
Regarding audio quality, I was pleasantly surprised. The sound is good, the bass is quite the appointment. I listened to a classical piece to see the difference with another pregnant and yes, the bass is there. After, it's not stereo or subwoofer enclosure but this fulfills the contract.
In short, an excellent speaker, so small and light, which can easily take it anywhere. And the best of the best, it promises to take twenty hours enough to take it everywhere and especially on the road when I go on vacation or on business.
