We are sorry that this microphone does not work. It is not actually a Canon device though, and not tested or supported specifically for your camera. We regret any inconvenience that this may cause you.

Is the jack plug a TRS or TRRS? If the latter this is why it works in a phone and not the camera. TRRS jacks in phones allow for the use of an inline volume control.
