Price vs. Performance is OK!

Positives:
+ Noble housing, good impression on unboxing
+ Good sound characteristics ...
+ Short charge time
+ Long battery life

Negatives:
- Too bad that you can not adjust the sound according to wishes. Suggestion -> via app or SW
- Some EQ presets own from Android Music Player is not supported in Bluetooth mode.
- A second device can not be operated while the other is active ... suggestion -> Bluetooth Connection should be after off / on reset, so that one can be a sign of other device.
Problem: if the device does not lezter logs (Bluetooth off) the other devices can not log in.
- Volume and next title keys are combined ... in practice it is not practical. Example: Increase the Volume / minimize Mussmann 1-2 seconds the key presses ... get used to it, but in this segment are also devices in it that they offer an Option ...
- When transporting man comes to the side speakers ... would probably represent problems if one simply throws in his pocket.
- In the package is not a USB charging adapter in it! hab adapter charged with my Samsung ... An adapter is supposed to be in there ... Herstellervorschalg is that you should charge it with notebook; what to Dan, if I do not have my laptop here ??)
- No info in the datasheet, how long you can still use the device after the LED flashes for low battery,

Conclusion:
for the price it's OK ... I hope the ideas will be integrated with the next generation of C1 some.
