DESC: Conforming to Bluetooth v1.2, the Motorola HS850 is at the forefront of Bluetooth headset design. Finished in black, with silver detailing, the 20g HS850 is superb to look at, as well as use. With the specification comes adaptive frequency hopping (AFH), which ensures that the connection with your phone is impeccable by shifting frequencies to avoid interference from other radio sources. The HS850 also delivers in the longevity department - an amazing 8 hours of talk time and 200 hours of standby time from a full charge a market leading figures, much like the rest of the HS850.
