Here are the steps: 

- Put both earbuds back into the charging case. Ensure both earbuds are charging (LEDs on the earbuds are blinking). Make sure you leave the charging case open.

- Press the button on the back of the charging case for 10 seconds until you see a red light flash 3 times on both earbuds. Then release the button.

- Leave the case open. Wait until you see one light flash fast and the other flash slowly.
