Practical speaker with restrictions

To be more specific: the appearance is good. Outwardly the little Brüllwürfel already like times.
The playing time I have not been able to really make fullest, there is unfortunately no battery level indicator. He is charged about once a week.

For purpose: He was supposed to be used as a BT speaker for smartphone / tablet. As others have noted, is the (sometimes more, sometimes less) with annoying noise associated. In my LG smartphone it is even so loud that this operation is totally excluded. Via audio cable, however it works properly.
The range is certainly in need of improvement, but adequate for the average application with 4-5m.

Why did not I sent him back? Well, he has proven to be quite practical. One can thus prima children press the MP3 player in his hand then listen to the podcasts in their own room. Alternatively, connect it to the PC, when there sometimes needs audio output. He's just very flexibly by the battery. For tablet and smartphone rich indeed usually the built croaker.

Speaking of cable operation: Yes it's true, the volume control on the speakers themselves only works in wireless mode. So far I had, however, still no device is connected, where I had to fully turn up the volume. I would recommend the "too quiet in the cable operation" so do not understand.

Conclusion: Due to the BT-weakness, the device is not suitable actually for wireless operation. Otherwise, the speakers but quite practical. A stale aftertaste remains. With a lot of goodwill 3 stars ...
