Bought as always delivered at Amazon quickly unpacked, charged app downloaded, connected to the phone - works. Everything totally easy and simple. Talk time: about 10 hours continuous phone calls possible.. When you turn the phone still remaining time will be announced, which I find totally good. Good sound quality even in a car with a lot of ambient noise well understood. Micro quality seems to be just fine, using it often and none of my interlocutors sulky. I have it more often on the ear because it's just easy lately and you can place the phone next to go, or put it in your pocket. The Bluetooth range is about 15-20 meters, in the apartment no problem there even further. I would that thing at once therefore buy full points.
