Description
The BT51 is the Bluetooth dongle for Yealink Bluetooth headsets and speakerphones. This USB-A connector version plugs into a laptop or desktop computer and handles the audio link with the BH70, BH71, BH74, BH76 and BH76 Plus headsets as well as the SP92 and SP96 speakerphones, without relying on the built-in Bluetooth of the PC. Bluetooth 5.0 and wideband audio keep the voice clear during calls and online meetings. The dongle is recognized on Windows 10 and 11 as soon as it is plugged into a USB 2.0 port. For computers without a USB-A port, the USB-C version (BT51 USB C) exists under a separate reference.

Use and tips
The BT51 USB-A is meant for anyone who uses a Yealink BH70, BH71, BH74 or BH76 Bluetooth headset, or an SP92 or SP96 speakerphone, with a computer: home office, shared office, mobile sales staff, meeting room. It replaces a lost dongle, equips a second computer or works around an unreliable built-in Bluetooth. Plug it into a USB-A port on the computer, pair the device and Windows 10 or 11 recognizes it as an audio device. Check the port type on your computer before ordering: the USB-C version (BT51 USB C) is available under another reference. For the CP700 and CP900 speakerphones, choose the BT50.
