Nothing exeptionnel well on this helmet, it works well, quickly load and allows for hands free while listening to music or making a call. For music nothing grand, it is not worth a helmet of high quality dedicated to this function as a brand B .... The sound is clear and correct, but for fun there is frankly much better, Its price is attractive, and the final choice will use, and if I want to make a call that will suit, but to listen to an album, and although my bluetooth headset with B .... by far the best. See according to usage
