Works without installation, sound quality (in terms of speech intelligibility and for this price) very good, Vererbeitung plastic but ok, and the comfort is enjoyable thanks to its low weight. The strap length of the headphones can be adjusted to the head size earcups are padded thin and do not press, the microphone can be swiveled around 160 ° (up and down), with the remote control on the cable, the microphone can be switched on and off and the volume be regulated for the headphones.
This headset offers an excellent price / performance ratio. Purchase recommendation
4 stars only because the sound quality for Musikhöhren MMN is insufficient, but as I said for this price fully justified and ok!
