The color combination of blue and black is beautiful solved. The speaker looks very valuable. A little bit smell the silicone, but only if you hold the speaker right under your nose.
For me, the Bluetooth connection worked for a smartphone with Bluetooth 3.0 and another with Bluetooth 4.0. The connection worked without problems. Is recognized the speaker as "C6".
The 4 controls are nice and big, but in the dark difficult to detect.
You can turn the music loud / quiet, use Forward / Rewind, Pause and a handsfree function and on / off switch.
Is charged via micro USB / USB on the PC. Cable is included. Unfortunately, there is no phone connection. So you could use the possibility still can enlarge as Walkman, PC ...
The sound is very treble-heavy. I'm still missing the bass.
Its range is approximately 10m. Playing time are 3-4,5h indicated. Standby 2 weeks. That sounds good.
The speaker has on the back a big sucker off. Thus there is a possibility it on glass (window pane) or tiles (bathroom) to attach. You could call him but also on / append (backpack).
The Bluetooth speaker is a good companion for sport, leisure activities, in the shower or in the garden. One can thus hear very loud or very soft music.
Price / performance is fully justified here.
