Jabra Headset Not Connecting to Dongle

by

When a Jabra headset is not connecting to its USB dongle (e.g., Jabra Link 370 or Link 380), it’s often due to pairing issues, outdated firmware, or USB port problems. This guide provides the most effective steps to troubleshoot and fix connectivity problems between your Jabra headset and its dongle.

Understand the Connection Setup

Common Models That Use Dongles
  • Jabra Evolve2 65 / 75
  • Jabra Engage 65 / 75
  • Jabra Speak series
  • Jabra Link 370 or Link 380 dongles

Connection Type
  • Dongles use pre-paired Bluetooth to connect to your headset.
  • They should auto-connect when plugged in-if not, manual pairing may be required.

Step 1: Check the USB Dongle Connection

Use a Different USB Port
  • Insert the dongle into a different USB port (preferably on the computer directly).
  • Avoid USB hubs, docking stations, or monitors.

Confirm the Dongle is Detected
  • On Windows:
    • Open Device Manager.
    • Look under Sound, video and game controllers or Bluetooth.
    • The dongle should appear as “Jabra Link 370” or “Link 380”.

Step 2: Pair the Headset Manually with the Dongle

Use Jabra Direct to Pair
  1. Install Jabra Direct.
  2. Plug in the dongle and power on your headset.
  3. Open Jabra Direct. If either device is not recognized, try reconnecting.
  4. Go to the “Bluetooth” or “Pairing” section.
  5. Select the dongle > click “Pair new device”, then follow prompts to pair your headset.

LED Behavior During Pairing
  • Dongle flashing blue: In pairing mode.
  • Headset LED flashing blue/red or just blue: In pairing mode.
  • Once paired, dongle LED should turn solid blue or white.

Step 3: Reset the Devices

Reset the Jabra Headset
  • Hold Answer/End Call and Volume Down for 5–10 seconds (model dependent) until LEDs flash.
  • This clears pairing history and restores factory Bluetooth settings.

Reset the Dongle (if supported)
  • In Jabra Direct, select the dongle and look for “Reset” or “Unpair” options.
  • Re-pair the headset after resetting.

Step 4: Update Firmware

Update Dongle and Headset Firmware
  1. Open Jabra Direct.
  2. If updates are available for either the dongle or headset, they’ll appear in the dashboard.
  3. Follow on-screen instructions to update both.
  4. After updates, reboot your PC and reconnect the headset.

Step 5: Disable Built-in Bluetooth (if needed)
  • On some systems, built-in Bluetooth may interfere with the dongle pairing.
  • Temporarily disable Bluetooth in Windows Settings and rely only on the dongle for the connection.

Step 6: Confirm Audio Settings

On Windows
  1. Right-click the speaker icon > Sounds > Playback/Recording tabs.
  2. Select your Jabra headset (via dongle) as the default audio device and microphone.
  3. Restart apps like Teams, Zoom, or Skype after changes.

When to Contact Jabra Support
  • The headset and dongle are not recognized in Jabra Direct.
  • Manual pairing via Jabra Direct fails repeatedly.
  • Dongle LED doesn’t turn on or flash when plugged in.
  • The headset works via Bluetooth but never connects through the dongle.

If your headset and dongle were originally paired as a set and are still under warranty, Jabra support may offer a replacement or re-pairing service.
