Remove the earbuds from the charging case to automatically power them on. Enable Bluetooth on your smartphone, search for 'King Lucky i121' in the available devices list, and select it to pair.
Place the earbuds back into the charging case. Long-press the touch control area on the earbuds for approximately 5 seconds to reset them to factory settings.
Many models, such as the i121, come with an IPX5 waterproof rating, protecting them against sweat and rain. However, they are not designed for submersion in water.
This often occurs if the earbuds fail to pair with each other (TWS connection). Put both earbuds back in the charging case, ensure they are charged, and remove them together to let them sync before connecting to your device.
On models like the i31Pro, you can often switch between Chinese and English voice prompts by tapping the touch area 5 times while the earbuds are powered on but not connected to a device.
