Much better than the price suggests!

This active speaker is a little stunner! What is not written here, he gives stereo and the volume is controlled by a small manipulation directly with the control of headphone volume of the connected equipment. The problem is that the device starts at reboot with the smallest volume, which is counterproductive depending on the connected source and placement of the device. As Soundbar behind an LCD TV, hidden installed eg as useless. But the solution is simple. Screw machine and the plug connection of the control board (easiest) Volume + to GND through a soldering jumper. However, if you do not get along with warranty problems must do this from the outside by mechanical manipulation. I also wanted the LEDs light up and have not yet had interrupted the + of the connection to the board.
A small switch on the device manufacturers have each other's Ansteuerproblem which some have already solved! When the manipulated unit starts "moves" this now at full volume and the input signal, respectively, the volume can be controlled directly via the KH starting now.
The power supply accepts a USB output of the unit, batteries or a USB power supply which may, in the low power consumption remain on the network or is switched on a power ON / OFF to turn the device hidden.
Unfortunately, you can not give 4.5 points, a small DIP switches Währe but the price sure was still in there.
But the face of the other power, playback, I give 5 points, the device to others quite.
