What are the notes for using a wireless microphone of the Redmi Buds 6 Pro?

The notes are as follows:
1. Only under LE Audio mode with Bluetooth connection, the wireless microphone mode can be used. Not supporting the use of wireless microphones under classic Bluetooth currently (with sound quality and latency issues). You need to switch to wireless microphone mode in the Xiaomi Earbuds APP first when connected to a flash connector;
2. In the wireless microphone mode of the flash connector, if worn on one ear, connect both earbuds, and place the other earbud on a desktop or far away from you, there will be a problem of one channel being larger and one channel being smaller in the upstream recording data.
