I have the silver version, the optically really looks great. The device is really stable and is well made. On one side there is the opening for the speaker, on the other hand is the cap. Behind the USB port cover to load as smartphones. In addition, here are two jack cable inputs. One of them is used to connect an audio output device to the speaker, the other invites you to the device battery.
The two cables are to connect with, a power supply, however, was to be expected, not included - you can use a common power supply with USB port.
The cap has two jack plugs that plug when plugging in the two jack outputs, whereby the cap really stuck and can not fall off - dissolved sent.
If you put a USB cable, the battery indicator will light up and you can see how full the battery is about yet.
Recharging works without problems - also play the music works perfectly: with the supplied jack-to-jack cable the output device (eg smartphone) to infect the machine and run music - already plays from the small speakers music.
Unfortunately, the sound quality is not really exhilarating - not surprising given the small device. Better than the built-in speakers in smartphones, the sound is indeed so, but one can not really expect too much.
Overall, you get with this device is a sturdy, well-made mobile battery that looks good and is well stowed and additionally a small (emergency) speakers offers. - And is perfect for a gift at Christmas, because the combination is something special - for myself, but I would not order it :)
