Small in size but very good sound

My initial need was to get a better sound that HP integrated into tablets and smartphones to mainly watch TV and videos.
The criteria were:
- Small size
- No proprietary format
- The best sound for size
- Good autonomy
After looking at the side of the mobile boombox Logitech mini jambox and Jawbone, it was by chance that I discovered Lowdi on Amazon.
Drawing on the various opinions found on the web, this speaker marketed by a French company seemed a good alternative.

After a few days of use, I must confess that I am not disappointed.
The packaging is nice and makes it fun unpacking. Too bad the two small boxes do not do that.
Coming out of the box, the enclosure seems really small and in good order. A cover and the cables are provided. However no charger, but the phone will be perfect to avoid walking an extra charger.
By turning the enclosure, a sound system is distributed and suggests that the beast in the belly.
Lappairage is very simple (tested on iOS, Android, PC and Mac bluetooth 2, 3 and 4).
We launch the music and there: amazed!
The sound is clear, powerful and the bass is correct for size. We will not compare the sound to that of a stereo, but Lowdi easily beeps in a room.
So, my use has expanded to listen to the radio and music. 4 Bluetooth connection (with an iPhone 5) provides high quality sound without as good a cable wire.
The range of Bluetooth is correct.
In terms of autonomy, very good surprise, always connected via Bluetooth, 8 hours are advertised widely exceeded for listening at moderate volume (and I still have).

As already mentioned in the comments, the speaker of buttons control the player, but the + and - buttons act in reverse.

In conclusion, I do not regret my purchase and am very pleased to have chosen Lowdi.
I hope this small enclosure will soon talk about it because it has its place among the best.
