Bluetooth Earphones Issue

Hello,

Thank you for writing to Microsoft Community Forums.

Glad to know that you were able to fix the issue. We truly appreciate for the details and, time and effort that you have taken to work on this issue.

However, there could be an issue with the drivers on the computer, where the drivers are getting conflicted and not recognizing the Bluetooth device properly and you are unable to hear the audio as it was supposed to, we will look into this for you.

• Could you please try using the Bluetooth device with a different computer and check if it works?
  

Please unplug the wired headphones and connect only the Bluetooth earphones and check if that makes any difference.

Please follow the below mentioned methods and check if it helps.

Method 1:

As you are unable to see the Bluetooth headphones after pairing to the computer, I suggest you to run the Bluetooth troubleshooter from the settings. Follow the steps below:

• Press Windows logo key + I, to open
  Settings.
  
• Select Update & Security.
  
• Click Troubleshoot and run the Bluetooth troubleshooting.
  

If the issue still persists, please follow method 2.

Method 2: update drivers.

The Bluetooth drivers could be out dated, hence un-pair the device from setting and update the Bluetooth drivers and check if that helps. Please refer the article

Update drives in Windows 10, expand Bluetooth device and follow the instruction from the above article.

Hope it helps.
