How to fool Skype so that it does not turn off hd voice in the case of connected bluetooth headphones with a microphone?

Question

Skype

The problem is that when you activate the microphone via bluetooth headphones with a microphone in Skype settings, the sound quality switches to very low quality (with reduced frequencies). This problem is on both desktop and phone.
How to hear the difference in sound quality? On the desktop, start a call with the Skype eco center and in the case of using a microphone through a bluetooth headset, the quality is one, if you use the system microphone, the quality is different. In the first case, the quality with very truncated frequencies.

Answer 1

This is not a limitation of Skype, it is a limitation of the Bluetooth protocol (profiles). Bluetooth does not have a profile for high-quality two-way audio (HFP), only one-way (A2DP).
So the problem cannot be solved, at least by standard means.
