You need to buy a plug in Bluetooth adapter. The one I have is this one, https://a.co/d/gItJsQl , but I'm sure you can find a cheaper one.
Go to Device Manager and disable your default wireless Bluetooth. It wont let me add pictures but you drop down the Bluetooth tab. Mine is called Intel(R) Wireless Bluetooth(R). Right click, "Disable device."
Plug in the adapter.
It should add itself to that drop down menu of Bluetooth devices. It will prompt a restart. Make sure the driver is up to date first/
Restart computer.
Now add the earbuds as a bluetooth device. They will work. Both my Tozo T6 earbuds and another wireless bluetooth pair I had started working perfectly after I did this.
(Edit: it is not a driver problem. It is a Windows 11 problem. Windows 11 wireless bluetooth is not compatible with most Tozo earbuds and they have said they will not be working on a fix.)
