How to reset the factory settings of Xiaoyi Audio?

Keep the speaker connected, press and hold the bottom reset button with a needle until you hear the voice prompt "factory settings are about to be restored" and release it, and the speaker will be restored to factory settings. After the speaker is restored to the factory settings, the original settings (such as distribution information, speaker name, Bluetooth status, do not disturb mode, wake-up response, voiceprint training, speaker volume, etc.). ) will be lost. Please reassign and set up the speakers.
