Thank you for your reply. So I have a “Rode Smartlav Lavalier Microphone for iPhone and Smartphones”, which appears to have a plug that will fit into normal headphone jacks. But it is too big for the hole in the back of the ZOOM that reads EXT MIC. Does that mean I need an adapter for “headphone jacks to 1/4 inch”? What is the normal measurement for a normal headphone jack? Thank you
