Here's the troubleshooting sequence that usually resolves it:
- Reset the pairing on both sides
- On the Surface: Settings → Bluetooth & devices → find the Sony headset → Remove device
- On the headset: put it into pairing mode fresh (usually hold the power/Bluetooth button until the LED flashes blue/white rapidly )
- Re-pair from scratch rather than trying to reconnect a stale pairing
- Check Surface Bluetooth driver status
- Device Manager → Bluetooth → look for a yellow warning icon
- Right-click the Bluetooth adapter → Update driver, or better, go through Windows Update → Optional updates for the latest Surface-specific Bluetooth driver
- Restart the Bluetooth stack
- Settings → Bluetooth & devices → toggle Bluetooth off, wait 10 seconds, toggle back on
- Or fully restart the Surface — this clears a lot of stuck Bluetooth states
- Check for interference/other connections
- Make sure the headset isn't already connected to a phone or another device (many Sony headsets only hold one active connection at a time even with multipoint)
- Move away from other Bluetooth/Wi-Fi congested areas temporarily to rule out interference
- Run the Bluetooth troubleshooter.
