Wearing the Earbuds
Gently insert the earbud into the ear canal. Ensure it does not move when you turn your head.
When making calls, ensure the microphone is exposed and orient the earbud accordingly. Point the earbud's microphone towards your mouth during a phone call to improve call quality.
Charging
Before use, remove the protective film from the earbud contact points to fully charge them and the charging case.
Use a USB charging cable to charge the charging case.

Using the Earbuds
Connecting Both Earbuds
Automatic Pairing: Remove both earbuds from the charging case simultaneously and wait 2-3 seconds for them to power on automatically. When the right earbud's indicator blinks white slowly, search for "Mi True Wireless Earbuds_R" in your device's Bluetooth settings. If you cannot pair the earbuds, place them back in the charging case and repeat the previous steps. After successful initial pairing, the earbuds will automatically connect to the device they were previously paired with when powered on (Bluetooth must be enabled).
Note: All earbuds have been reset at the factory and can be directly paired with a device.
Manual Pairing: If the earbuds are off, manually turn on both earbuds. Both indicators will blink white rapidly. Once the connection between the earbuds is established, the right earbud's indicator will blink white slowly. Enable Bluetooth on your device and connect/pair it with the earbuds.
Using a Single Earbud
Automatic Pairing: Remove one earbud from the charging case and wait for it to power on automatically. The earbud's indicator will blink white rapidly, then slowly. Enable Bluetooth on your device, search for "Mi True Wireless Earbuds_R" or "Mi True Wireless Earbuds_L", and then pair your device with the right or left earbud, respectively. After successful initial pairing, the earbud will automatically connect to the device it was previously paired with when powered on (Bluetooth must be enabled).
Note: The left earbud (L) has a relatively long time for automatic pairing.
Manual Pairing: If the earbuds are off, manually turn on one earbud. When the indicator blinks white slowly, enable Bluetooth on your device and pair the earbud with your device.
Resetting the Earbuds
If pairing fails, follow these steps to reset the earbuds: Remove the earbuds from the charging case and ensure they are powered off. Press and hold the touch panel on both earbuds for approximately 15 seconds. Once the indicator blinks red and white alternately three times, release the touch panel and place the earbuds back into the charging case. Remove the earbuds from your device's list of paired devices and then pair them with your device again.
