The Voyager 6200 UC headset utilizes Bluetooth technology to wirelessly connect to your devices. With its support for multiport technology, it can pair with up to eight devices, and actively connect with two of them simultaneously. Support for Class 1 Bluetooth means that you can enjoy your wireless connection from up to 98' away when the Voyager 6200 is paired with a Class 1 device. If you want to connect the headset to a Mac or Windows PC that lacks Bluetooth, you can use the included USB Type-A Bluetooth adapter.
