Galaxy Buds Plus missing audio quality options for Microphone

An innovation that I found valid, but lacking refinement was in terms of Bluetooth connectivity. Finally a distro that identified the microphone of my Galaxy Buds Plus, but they still need to make specific corrections: when selecting the microphone of the galaxy buds Plus (input) to (output) speakers of the headphones, the sound is bad, I select the available items and none demonstrates the quality of the Profile: High Fidelity Playback (A2DP Sink) item that is the best.

Please use it and know some technique to improve the sound quality
after activating the TWS Galaxy Buds Plus microphone help me.
