14. About the remote control and microphone function in RETRO NANO

RETRO NANO only supports calls in BT mode and supports the in line microphone function.

[Is it normal for RETRO NANO game voices to have sound quality deviation? ]
The poor sound quality of game Bluetooth voice is due to the game app and mobile phone system, and many mobile phones will switch to mono mode after entering the game, and the sound quality is even worse at this time. It has nothing to do with RETRO NANO directly.
