Simply turn on the headset to establish a reliable wireless connection to a compatible phone up to 32.8 feet away. The headset's Bluetooth 1.2 compatibility means that you'll enjoy faster connections, better audio quality, adaptive frequency hopping and improved interference rejection (don't worry, it's also compatible with the older Bluetooth 1.1 specification). With up to six hours of talk time, you can converse to your heart's content before you'll need to charge the HS820's internal battery. The headset also has up to 100 hours of standby time, so you're always ready to receive a handsfree call.
