Why do two Bluetooth names, Stereo and Hands-Free, appear after connecting the Xiaomi Desktop Speaker Pro Set to the computer via Bluetooth?

If two Bluetooth names appear after connecting the Xiaomi Desktop Speaker Pro Set to the computer via Bluetooth, please refer to the following details:
1. Hands-Free refers to a Bluetooth communication mode in the Windows system designed primarily for voice calls. It is optimized for voice transmission and is not fully suitable for high-quality audio playback. When the speaker’s microphone (MIC) is in use for calls, Windows will automatically switch to Hands-Free mode. After the MIC is turned off, the system will automatically switch back to Stereo mode.
2. When two devices appear in the computer’s Bluetooth device list, please select Xiaomi Desktop Speaker Pro Set-XXXX Stereo for connection and playback, as it provides better sound quality and clearer music.
