Press the button to turn on and do not release the multifunction key for a while after turning on the power, while the red and blue lights and the headset are on. The lights will flash for the first time to restore factory settings,; and they will flash a second time to clear pairing information
To pair the headphones with each other, it is enough to get them out of the charging box and wait until they connect together. The bluetooth on the smartphone should be turned off
