Since Windows 11 can detect other Bluetooth headphones, focus on pairing visibility and Windows Bluetooth discovery rather than AAC. AAC affects audio playback quality after connection; it does not control whether the headphones appear during detection.
Try this in order:
- Confirm the headphones are actually in pairing mode and close to the laptop.
- Turn the headphones off, wait a few seconds, then turn them back on in pairing mode.
- Keep them within range of the PC.
- If possible, move them away from USB 3.0 devices, because unshielded USB devices can interfere with Bluetooth.
- Make sure Bluetooth is on and airplane mode is off on the laptop.
- Select the Network, Sound, or Battery icons on the taskbar.
- Verify Bluetooth is on.
- Verify Airplane mode is off.
- Change Bluetooth discovery to show all device types.
- Go to Start > Settings > Bluetooth & devices > Devices.
- Under Device settings > Bluetooth devices discovery, change it to Advanced.
- Then try Add device again.
- Toggle Bluetooth off and back on.
- Go to Start > Settings > Bluetooth & devices.
- Turn Bluetooth off, wait a few seconds, then turn it back on.
- Try pairing again.
- Remove any old Sony or headphone entries and re-add.
- Go to Start > Settings > Bluetooth & devices > Devices.
- If any old entry for the headphones appears, select More options (...) > Remove device > Yes.
- Then select Add device and try again.
- Update the Bluetooth adapter driver from the correct place.
- Checking Sound, video and game controllers is not the right place for Bluetooth detection issues.
- Open Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter and select Update driver > Search automatically for drivers.
- Restart the PC after the update.
- If Windows says the best driver is already installed, install the latest Bluetooth driver from the laptop manufacturer.
- Go to the laptop manufacturer’s support site.
- Search by the laptop model.
- Download and install the latest Bluetooth driver for Windows 11.
- Restart the PC.
- Run the Windows Bluetooth troubleshooter from Settings as well.
- Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
- Next to Bluetooth, select Run.
- If the driver still seems stuck, reinstall the Bluetooth adapter.
- Open Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter and select Uninstall device.
- Restart the PC.
- Windows should reinstall the Bluetooth driver automatically after restart.
The most relevant next steps for this specific case are:
- put the Sony headphones into pairing mode again,
- set Bluetooth devices discovery to Advanced,
- update or reinstall the adapter under Device Manager > Bluetooth,
- then install the latest Bluetooth driver from the laptop manufacturer if needed.
