How can I keep voiceover coming out of the iPhone speakers when there is a microphone going into the 3.5 jack?

Hardware & Accessories


I'm starting some podcasts, got this nice little lapel mic which I intend to use with my iPhone when I'm out and about, however, when I plug it in to my iPhone 7, using the lightning adaptor, speech stops. I'm assuming that my phone thinks that it's a pair of headphones. Has anyone got any experience in this and can you suggest how I might get VO working as, forgive the term, I end up using my phone blind, IE, remembering the gestures to get to record etc.
