Is it possible to trick Win11 into thinking Bluetooth headset is wired headset?

Hi everyone,
I have just recently found out that as soon as you enable the microphone on a Bluetooth headset, the audio playback quality goes waaaay down (I know, I am late to realize, but usually I only use the mic for meetings).

Now, this does not seem to be a real BLE bandwidth issue but rather a forced problem by Windows (?) or some driver.

I would like to trick my system into thinking thta my microphone is a hardwired device. Ideally same for the speakers.

I installed Virtual Audio Cable (which seems to no longer be active, maybe now focused on their Matrix solution?) but I cannot "route" the bluetooth mic through it.

So, what I was thinking is:

1. Find a driver (like Virtual Audio Cable) that is able to listen to the bluetooth microphone even when the bluetooth microphone is not default. This driver should pretend to be a cable connection (to prevent sound quality degradation).
2. Find a driver that routes ALL sounds to the bluetooth headset. This driver should pretend to be a cable connection (to prevent sound quality degradation).

Does anybody know if this is somehow possible?

Thank you all for your help
Alex

Do you know what version Bluetooth you have? I think that Bluetooth 4.x had bandwidth limitations. Because of this when you had to have the audio set to mono instead of stereo to use the microphone. I thought that would change with Bluetooth 5.x but have not heard where the problem was even fixed.

I have read that is not a problem with some other wireless technologies but can't confirm that. If you really want better headphone audio then you might have to stick with wired headphones.

Currently to use my microphone with my Bluetooth headset I have to select Bluetooth Hands-Free AG Audio. When I do that the headset audio is mono only. Note if I select the playback audio to be Bluetooth Stereo then the microphone is disabled.

I read somewhere that BlueTooth 5 can connect multiple devices at one time, but it can support only one being active at a time. This means (if true) that is can only transmit and receive data from one device at a time.

I tend to believe this because I just converted my wired keyboard and wired trackball to wireless ones. The trackball can be either BlueTooth or wireless USB, and the keyboard can be only Bluetooth. I first tried connecting both to Bluetooth, but that resulted in strange things happening. Sometimes the mouse would move herky-jerky on screen, and sometimes the keyboard would not respond at all. So I switched the trackball to wireless USB and now both devices work properly.
