You can delete the Bluetooth records on the mobile phone:
Go to the [Settings] APP on the phone >> select [Bluetooth] >> the Redmi Buds 6 Lite >> tap [Unpair] (Take the Xiaomi mobile phone as an example);
You can reset the earbuds by referring to the method as follows:
Keep the lid of the two earbuds open in the case, make sure the box is powered, press and hold the function key for about 10 seconds and then release it. The box light will flash 3 times after being pressed for about 10 seconds. The earbuds are reset successfully and enter the pairing state.
The reset process will clear the connection records between the earbuds and the devices. After the reset is completed, the earbuds will reenter the pairing mode.
Note:
Due to the nature of Bluetooth connections, intermittent disconnections or silent periods will occasionally occur in places with high electromagnetic interference like airports, train stations, near microwave ovens, in subways, or near traffic lights.
