A:Answer You press the button on the left ear bud. There is a white LED to show it is on. Long pressing this button will cause the LED light to glow brighter and then fade out—its off. You go to settings, blue tooth, and it automatically pairs with your iPhone. I don’t know how it would pair with an Android based system. I wear these earbuds about four hours a day. The last time I plugged it in, was yesterday. When you go to settings, on your iPhone and press Powerbeats (connected) it tells you how much charge it has.
