When you power ClearDryve on for the first time, it automatically enters pairing mode. In pairing mode, the LED indicator blinks blue and you will hear the word “Pairing.” After ClearDryve has been paired with a device at least once, the headphones will attempt to reconnect to the device upon powering up. If a second phone (or device) needs to be paired, the user must explicitly go to pairing mode to do so.  This is done by turning off the device and turning it back on by pressing and holding the Power / MFB button.
