Ingenious traveling companion

First things first - the sound:
Of course you can and can not expect from such a small cube no miracles.
The basic sound is rather middle-heavy, yet not intrusive. After a short time you have been listening to and it sounds definitely more pleasant than the speakers of smartphones or tablets.
The volume looks not to the size of the cube. It is basically controlled by the connected device - the cube itself has only one on / off switch and no controls for the volume. It may therefore be variations in different devices here.
So I have found, for example, that the lowest volume of the iPhone / iPad's enough for background accompaniment. On my Android and Windows Phone the quietest level was a little quieter.
But full blast loose enough to fill a social evening - let's see how it is in summer, on the balcony or in the garden.

Operation:
There is only one button - on / off. If you switch to a cube, he automatically goes into pairing mode. All my devices have found it immediately and were able to connect easily. The Windows Phone has then always automatically connect to the cube. I had to become active separating to pair another device.
The i-devices in the Bluetooth icon and the battery status of the cube was displayed (not with Windows and Android). I think that's super convenient - because the LED begins to flash, it does not have much juice. Thanks to this display you can ever charge in advance via the supplied USB cable. A plug adapter is not included, however. In regard to the application (smartphone) but this is to get over, because every standard USB power supply is functioning.

Anything else:
The battery lasts felt extremely long. I've done more than an 8-hour day and had so loud display still almost half of electricity. Loading naturally depends on the power supply used. I tried it with both the iPhone and iPad power supply - both goes very quickly (iPad naturally even faster).
In addition to the USB cable, an adapter is included to catch (eg for discman or older phones). Tucked is all in a small bag - so you always have the necessary items together.

Conclusion:
For the price an absolute cracker. In size, I expect any sound miracles. There is a speaker for the office, presentations or cozy evening in the garden. Due to the long term also very independent from the power. The design is attractive, compact. Nothing rattles or booms. The production quality is 1a, very well finished, everything is in place.
