Hi, Thomasdqr!
Thanks for reaching out to Microsoft Community. We are sorry to learn you have issues with your Surface Headphones 2 when connected to your Surface Laptop 3. Thanks for taking the time to let us know about this.
Please allow us to ask these questions:
-Do you happen to have another Bluetooth accessory connected to your host device?
-Does it exhibit the same issue?
-Have you tried turning off your smartphone's Bluetooth before connecting the headset to the laptop?
In the meantime, please do these steps on the device:
- Run Bluetooth troubleshooter.
Go to **Settings > Update & Security > Troubleshoot >**look for Bluetooth and run its troubleshooter.
Please restart your device to apply the updates.
- Run Surface Diagnostic Toolkit and make sure to complete the tasks.
- Force shutdown the device and restart.
1.) Press and hold the power button until the screen turns off (about 10 seconds), then release the power button.
2.) Press and release the power button to turn your Surface back on. You should see the Surface logo.
If that doesn't work, use this two-button shutdown process to make sure your Surface turns off completely:
1. Press and hold the power button on your Surface until the screen turns off (about 30 seconds), then release it.
2. Press and hold the volume-up button and the power button at the same time until the screen turns off (about 15 seconds), then release both.
The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds.
3. After you release the buttons, wait 10 seconds.
4. Press and release the power button to turn your Surface back on. You should see the Surface logo.
Let us know how it goes.
Kind regards,
Janette_Z
