I just bought this piece last week. Very light, sound quality is good. The best part I liked about the unit is that I do not need to power cycle the device so to reconnect when it was disconnected because of the distance. Here comes the bad part - the usability which is very important for the day-to-day use of the device. 1) charging method is very weird (need to put in a charging case) 2) Earloop is very cheap quality and does not fit around the ear firmly 3) Need to remove the earloop before you recharge the unit everytime 4) Everytime you remove the putback the earloop during recharge could damage the earloop (it is broken during the 2nd time I tried to recharge). Technically it could be a 5 star but it failed in usability.
