Agreed with most of the posts since the OP, Windows is definitively the worst implementation of Bluetooth. My PC has Bluetooth 5 hardware and I have a great set of BT headphones by Shure (aonic 50s) but Microsoft have chosen typically to fail the users by only allowing Output to have any audio quality and denying quality entirely for users of decent bluetooth headsets and defaulting all of us to 16KHz when using 2 way BT.
Microsoft will claim once again they listen to users. Anyone could easily mistake MS for a politician...
