The headphones start automatically and pair automatically. Take out two headphones from the charging box at the same time. You can see the two headphones flashing alternately for about 2-3 seconds. The left and right headphones turn to red and blue lights. The headphones prompt the pairing success and the headphones can be used. When the red and blue lights are flashing slowly, double-click the (L)earbuds or(R) earbud button to switch between game mode and music mode
