After 24 hours of use with multiple devices, I must say I am very satisfied. Certainly we do not reach the quality of a HiFi but it is much better than the sound from the speaker of my phones / tablets ...
The speaker beeps in no problem living room, kitchen. Ideal for those who like their music follows them everywhere without wearing a helmet.
The battery life is excellent since I was able to use it at least 5-6 hours a correct volume.
Tested in communication with my Nokia 8800, my correspondent does not hear echoing contrary to what I read in other reviews ...
NFC works perfectly with my Samsung Galaxy Note 2 or even my Samsung Galaxy S4 Zoom.
Finally, I find really excellent finish. The materials are of quality, the adjustments between different parts too. The point is therefore enough to have that feeling of solidity and a finely crafted product.
Initially, I had gone to buy a Xmini certainly much cheaper but is not Bluetooth. I eventually regret having chosen this nomadic pregnant Sony!
I definitely recommend.
