To pair the Redmi Buds 6 Lite to a new phone after pairing it with other phones, you can put the earbuds into the charging case and press and hold the function key for 10 seconds until the indicator flashes three times, and then release the key. The case will turn to a white light that flashes slowly and the earbuds will enter the connecting state, and then you can use a new phone to connect.
Note:
The Redmi Buds 6 Lite does not support dual-device connectivity.
