Very good helmet with a rather impressive sound quality (especially the bass). Convenient charging dock. It fulfilled its role whatsoever to play or listen to music, watch a movie but there is no configuration software supplied (not USB keg). The use requires a minimum of information, it is not very intuitive. And can not use the microphone when the headset is connected optics (which is a shame because the sound quality is much better optics). A little disappointed, at this price is expected to perfection ...
