Bluetooth Connection Issues With Dell Wireless Headsets

Affected Dell wireless headsets may not correctly appear in Microsoft Teams as an available microphone device. The microphone device may not appear at all, or the speaker device may appear twice, as both a Dell WLx024 Headset Hands-Free and Dell WLx024 Headset.

Affected Headsets:

• Dell Pro Premium Wireless ANC Headset WL7024
• Dell Pro Plus Wireless ANC Headset WL5024
• Dell Pro Wireless Headset WL3024

A Windows drivers pointer issue causes this error.

If experiencing Bluetooth connectivity issues with an affected Dell wireless headset, try the following steps:

1. Update the headset to the latest firmware using the dongle using Dell Display and Peripheral Manager (DDPM) or the standalone installer from Dell Support.
2. Ensure that the computer is up to date with the latest BIOS and Bluetooth device firmware. If using a Dell computer, reference:
   • BIOS Update Guide

3. Clear the Microsoft Teams application cache.
   1. Quit Microsoft Teams.
   2. Right-click the Start button and then click Run.
   3. Type %appdata%\Microsoft\Teams and then click Run.
   4. Delete all files and folders in the directory.
   5. Start Microsoft Teams.
      Note: For more details, see Clear the Teams client cache.
4. Restart the computer if the hibernate function is typically used.

If the problem persists, then restart the headset when the issue occurs.
