Press and hold the center button on the inline microphone located below the right earpiece. It helps to have one of the ear inserts in your ear to listen to the audible voice prompts. If this is your first time using the headphones, the headphones will automatically go into search mode. You will hear the audible voice stating, “power on” followed by “looking for device”. To power off, press and hold the center button on the inline microphone until you hear the audible voice stating, “power off.” The flashing LED light should change to a solid red light before completely turning off.
