BT51-C

The Yealink BT51-C is the USB-C Bluetooth dongle supplied with Yealink BH-series wireless headsets, giving a plug-and-play connection from a PC or laptop to the BH70, BH72, BH74, BH76 and BH78 with a range of up to 30 metres, and a stable link that native Bluetooth often cannot match.

ARC IP Networks supplies the genuine Yealink BT51-C in Australia with manufacturer's warranty and GST invoice.

Yealink BT51-C overview

Yealink pairs its Bluetooth business headsets with a dedicated USB dongle because a tuned dongle gives a more reliable link, better range and full call-control integration with softphones than a laptop's built-in Bluetooth. The BT51-C is the USB-C version of that dongle; the BT51-A is the USB-A version.

It is pre-paired to the headset it ships with, and can be re-paired to another compatible Yealink headset through the Yealink USB Connect application, which also handles firmware updates. Use it as a spare for a second computer, a replacement for a lost dongle, or to add a dongle-based connection to a headset bought without one.

Key features

  • USB-C Bluetooth dongle for Yealink BH70, BH72, BH74, BH76 and BH78 wireless headsets
  • Plug-and-play PC connection with up to 30 m / 100 ft range
  • Enables softphone call control (answer, end, mute) through the headset
  • Pairing and firmware management through Yealink USB Connect
  • Black; compact low-profile design
