Recentrly I've found the question
on page https://discussions.apple.com/thread/251558671
So, I have macOS Big Sur 11.2.3 (20D91)
And it works, just follow this guide:
1. Open System Preferences and select “Sound.”
2. Select the Input tab, and then choose “Logitech USB Headset.”
3. Select the Output tab, and then choose the “Logitech USB Headset.”
Close the window.
