So, plugging a TRS jack into a TRRS socket won’t work. So the first problem is that some microphones come with a TRS jack and not the TRRS jack that iPhones support. The headphone socket on an iPhone only takes 3.5mm TRRS jacks. There is an issue about 3.5mm jacks and iPhones you need to be aware of. If you use an iPhone with a headphone socket, you can’t plug in just any 3.5mm mic. At least it did until Apple removed the headphone socket from the iPhone 7 and later models. So, the headphone socket allowed audio both in and out. Of course, you could also plug in an external microphone to record quality audio. You could also use the built-in microphone on your earbuds to make calls or record audio. So, you could listen to calls or your favorite music on your earbuds. It could pass audio both into and out of your iPhone. Until the iPhone 7 came along, the iPhone’s headphone socket had a dual function.
