If you have a Kinect and it is activated to use chat, then it will always show up, but it does not work in game chat on Destiny. To disable it go to Settings>Kinect and then disable either "Use Kinect microphone for chat" or turn off the Kinect completely by unchecking "Kinect On." Of course though the icon will show up if you have a microphone connected to your controller.
