Jabra Link 390A UC USB-A Bluetooth Adapter

The Jabra Link 390A UC is a compact, high‑performance Bluetooth adapter that brings reliable wireless connectivity to your Jabra headset or speakerphone. Designed for Unified Communications (UC), this USB‑A dongle plugs into any computer and provides a stable, interference‑free connection up to 30 meters (100 feet). Unlike standard computer Bluetooth, the Link 390A delivers wideband audio, remote call control, and seamless integration with Microsoft Teams, Zoom, and other UC platforms. Whether you are in a busy open office or a home workspace, this adapter ensures your Jabra device performs at its best.

How It Works

Plug the Jabra Link 390A into any USB‑A port on your PC, Mac, or Chromebook. The adapter is plug‑and‑play – no drivers required (though Jabra Direct software can be used for firmware updates). Pair your Jabra Bluetooth headset or speakerphone with the adapter using the simple button‑press pairing process. Once paired, the adapter automatically reconnects whenever you are in range. The Link 390A provides a dedicated audio connection with wideband speech quality, far superior to standard Bluetooth. It also enables remote call control – answer, end, and mute calls directly from your headset when using softphones.
