After pairing, test the audio to see if the lag has improved.
3. Restart Windows Audio Services

6. Check for Hardware Issues
Consider using an external USB Bluetooth adapter to improve stability and performance.
Ensure the adapter supports the latest Bluetooth version, such as Bluetooth 5.0.
Connect the Bluetooth audio device to another computer or smartphone to see if the lag persists.
If the lag occurs only on a specific PC, the issue may be related to the computer's hardware.
If the Bluetooth audio device itself is faulty, contact the manufacturer for repair or replacement.
