Just received today. The sound quality is excellent; Clarity is excellent, but I also understand that this depends heavily on the caller's phone. I've only used this with my mobile phone, but it connects to my desktop and can be used with Skype. All in all I am very impressed. I don't know yet how long the battery will last, but I think it should last a normal work day without any problems. UPDATE 2/15/19: I received this device in mid-December and have been using it daily ever since. . Everything was fine at first, but in the last few days the battery life has dropped sharply and the call quality has deteriorated sharply. The incoming voice is ok, but the outgoing people say I'm breaking up. I stopped using it and went back to my Logitech H800 headsets and everything is fine so I don't think it's a problem with my phone/bluetooth. The unit is said to be covered by a two year warranty, so I will try to return it to Logitech for any type of repair or replacement. But now I have to say don't buy it. If Revain's return window hadn't closed yet I would try to return it as defective.
