Problem Description:
The earphones connect properly to the phone, but not to the laptop.
Causes:
The laptop did not adjust the Bluetooth devices discovery option to Advanced.
Solution:
This is caused by the Windows 11 system settings, not the device. When adding a Bluetooth device, Default lets you connect common accessories. You can choose Advanced to see all types of devices.
1. Open Settings (Win+I).
2. Click/tap on Bluetooth & devices on the left side, and click/tap on Devices on the right side.
3. Under Device settings, select Advanced in the Bluetooth devices discovery drop menu for what you want.
