A:Answer Cycling between noise cancelling, ambient sound, and off (normal headphones without the two previous features) can only be done by pushing a button on the headphones and you can only tell what mode you are in by listening to it. There's a different tone for each one and then it tells you with words. Every time you turn it on it defaults to noise cancelling. Ambient sound is next, followed by off (followed by noise cancelling again if you keep cycling through the modes)
It also tells you when power is turned on or off, when bluetooth is connected, and what the battery level is. But you can also get this information out of your phone.
You don't need a pin or code to pair with your phone. Look for WI-SP600N in the list of bluetooth devices.
