If connecting for the first time, the headphone will enter pairing mode automatically after it is powered on. To turn the headphones on, simply spread apart the RIGHT power hook from the cord. You will see solid red LED and then it will flash blue as it begins to search for a device to connect to. The Endurance headphone should pop up on your discoverable devices within a few seconds and you should be connected! If you wish to turn off the headphones, remove them from your ear and allow the RIGHT power hook and cord to close together. This is magnetized, so they should close together with ease.
