Sound performance:
- The sound output is good, whether the treble as serious.
- The range of volume is satisfactory (I do not perceive quality loss when the volume is at its maximum).
- Good bass.
Pregnant with solid hull and reduced at the space occupied, all complemented by modern design: it's perfect! When taken in hand, we feel that the quality is there.
Battery life seems very good: a week ago I received this gem and using it every night a little less than an hour, I have not needed the recharge (no sign of weakness or LED for low energy level.
Bluetooth recognition is very fast, but I recommend turning on the Bluetooth speaker after the other device is activated (difficulty if not the connection).
In short, everything I've tested so far has been a success. The price / quality ratio looks very good to me!
I highly recommend it! :)
