Connection

Automatic Connection

1. Remove both earbuds from the charging case simultaneously and wait 2-3 seconds for them to automatically connect with each other. Ensure Bluetooth is enabled on your device. When the indicator of the left or right earbud slowly blinks white, search for "Mi True Wireless EBs Basic S" on your device.
2. Once your device and earbuds are successfully connected, your earbuds will automatically connect to the previously paired device (with Bluetooth enabled) when they are turned on.

Note: If you cannot pair the earbuds, place them back in the case and repeat the previous steps.

Switch between single and dual earbud

When both earbuds are connected successfully, they are in dual-earbud mode. Place one earbud back into the charging case and close its lid; the other earbud will automatically enter single-earbud mode. Remove the earbud from the charging case, and the dual-earbud mode will be automatically restored.

Reset Earbuds

If the earbuds cannot connect properly, follow these steps to reset: Remove the earbuds from the charging case and ensure they are turned off. Press and hold the multi-function button on both earbuds for about 15 seconds. After the indicator alternately blinks red and white three times for twice, release the button and place the earbuds back in the charging case. Delete the earbuds from the list of paired devices on your device, and then pair them with your device again.
