Is it possible to improve the sound quality in a bluetooth headset in the "telephone" profile?

Question

Bluetooth

Good day.
I bought a SVEN AP-B450MV and immediately ran into a "bluetooth trick" with a decrease in sound quality when the microphone is on if the headset is paired with a computer. When paired with a mobile phone, there are no particular complaints about the sound, which suggests some kind of "conversion" in windows7 with a loss of sound quality.
Off support stated that "in headset mode, the sound is designed to reproduce speech, so the frequency range is highly compressed and the sound quality is unacceptable for playing music or movies." Everything is clear about the transition of headphones to a telephone profile, but the sound is not only unacceptable for music, it is unacceptable even for simply listening to an interlocutor ...
I tried to pick the registry in the bluetooth adapter settings branch. I did not achieve positive results, because everything was cunningly done there.
Tell me if there is a solution to this problem?

Answer 1

No. As there was no solution in 2015, so there is none in 2020.
