USB dongle for Bluetooth headsets
You might be somewhere in your building and you need to stay connected with clients, co-workers, or other executives. The BT40 USB Bluetooth Dongle is something that you shouldn't run the office without when you want to take calls any place, anywhere in your office building. It's compatible with the latest Bluetooth technology (and older). You can easily connect to your Yealink phone that has USB capabilities and be able to get the same crystal clear call quality no matter where you are.
