This headset is a real gem: * Although no ear hook, it fits comfortably in the ear and without causing discomfort. Note that I have not tested while playing sports. * The lack of earhook significantly facilitates its implementation when wearing glasses * The sound is very clear and received a more than adequate * The sound received by the person you are speaking with is also very clear: at 130 km / h or stopped, my party can not hear any difference ... Autonomy is sufficient, since it corresponds to the autonomy of most mobile phones ... Furthermore, the case allows to recharge 2 times completely without access to a power outlet.
