Issues connecting Sony WH-CH720N Bluetooth headphones to a Windows 11 laptop.

Hi,

I'm experiencing issues connecting a pair of Sony WH-CH720N Bluetooth headphones to a Windows 11 laptop. To summarise:

  1. The laptop is completely up to date as far as updates and drivers are concerned.
  2. The headphones are on the latest version of firmware.
  3. I have attempted to pair the headphones with the laptop but the device is not discovered.
  4. I have attempted a reset of the headphones (plug into charger, press Power and NC together) with no effect.
  5. I can connect the laptop via Bluetooth to a JBL Flip 6 speaker and a Panasonic SC-DM502 music system.
  6. I can connect the headphones to a Sony NW-A55L DAP and Nokia G21 smartphone.

This appears to be a common problem and I have tried all the suggestions I can find, short of a factory reset of the headphones, which I'm loathe to do while I can connect to other devices (point 6). Anything you can suggest would be much appreciated.

    Hi Jerry,

    There's a separate entry for 'Bluetooth Device(RFCOMM Protocol TDI)' and 'Realtek Bluetooth 4.2 Adapter'. Do I uninstall both?

    Yes. Apologies, it's restore default.

    Also to add on that if incase that steps doesn't work, you can also try this troubleshooting steps below.

    • Open the Start menu by clicking on the Start button
    • Type "Device Manager" in the search bar
    • In the Device Manager window, expand the "Bluetooth" category
    • Right-click on your Bluetooth adapter/device and select the "Uninstall device" option.
    • Once the Bluetooth device is uninstalled, restart your computer.
    • After restarting, your computer will automatically reinstall the Bluetooth device drivers. (You also double check if bluetooth is installed by checking device manager)
    • After that you can try to pair you headset again.
