Powerful companion on the road!

The speaker is schörkellos and functional. It comes in a businesslike yet visually appealing and clean processed design. The functional elements such as on / off, volume up / down, AUX, Micro-USB, LED indicator light and microphone are simply installed and working properly. It is handy that the battery is replaceable (he should ever go wrong ...).
The loudspeaker is not only powerful and flexible, but also simple to connect via Bluetooth with the usual sources such as tablet, PC, iPhone or smartphone. The LED lamp indicates at the back the connection status recording - blue / red alternately = search is still in progress, made blue = Connection. Up to a distance of about 8m the reception was ok. If the stations do not have Bluetooth, so can the speakers connect easily using the included 3.5mm audio cable from the audio output socket of the transmitter. The quality of the audio is surprisingly good and thanks to the powerful long-lasting rechargeable batteries (can be loaded even during operation). The multifunction button serves as Stop / Pause button and the short pressing the + button or key, the volume can be changed. When pressed longer each, playback skips to the next track (+) or previous (-).
Should we be disturbed by a phone call in listening to music, you can call by pressing the multifunction button also (ie to take the call and talk via built-Micro). However, the quality is not very. But can in my opinion also neglected, since it is a speaker and no telephone.
