If the Redmi Buds 6 Lite has been connected to other devices and the pop-up function is supported, it will prompt that this is not your earbuds, which is a normal phenomenon.
There are two methods to connect earbuds in this situation:
1. Put the earbuds into the charging case, open the lid, and follow the pop-up prompts to connect the phone with the earbuds;
2. Place the earbuds in the charging case and press and hold the function button for 10 seconds until the indicator flashes 3 times. Release the button and the earbuds will enter the connecting state, allowing the new device to connect.
