Firstly this headset is an incredible comfort, it is not used too ears and still holds well on the head. it is not too heavy, and circum-aural headphones (not crowded ears) allow listening without pain for many hours. Then the sound quality is clear to the appointment, the entire sound spectrum is occupied, the spatial experience is omnipresent. Finally the wireless feature is quite useful, and works well, it passes through a wall and a range of several meters. I did not test the battery life but it seems correct. for compatible smartphone, the buttons on the headset are also a plus, although it would have been nice to let them functional even connected via cable.
