I took it until "black Friday", before they hung "discounts", for 9890. Worth their money. Although for 12-13k I would consider other options. Pros below: Good signal. Sound quality suits. Interlocutors do not complain about the microphone. Does not lose connection from anywhere in the apartment. The operating time is as advertised. Cons below: At first, they sit tight on the head. Micro-usb charging (USB Type-C would be better).
