Hello there! I am Charity, I'm an Independent Advisor. I'm glad to help you today!
My apologies about that. Please Make sure your headphones are not connected to any other device and that there are no barriers or interferences, such as walls or other Bluetooth devices, between your headphones and your laptop.
Also, Ensure that the Bluetooth Support Service is running on your laptop. You can check this by typing "Services" in the Windows search bar, finding the Bluetooth Support Service, and setting its startup type to "Automatic." If the service is already running, try restarting it.
Please let me know if this worked for you.
Kind Regards,
Charity
