I'm getting conflicting opinions as to whether I can plug an external mic into my Android phone.

I just want a small cheap wired mic, nothing complicated, but differing sites say you can plug a 3.5mm jack into the headphone socket, or you might need some sort of splitter for the 3.5mm socket, or you plug a mic in via the USB-C socket.

Anyone done this before?

You used to get a combined earphone and microphone with phones (quite) a few years back, I expect the software functionality is still in there.

What are you wanting to achieve from the external microphone? Is it to improve call quality or for media recording?

I spend a lot of time on hearings / conference call type calls and have a headset (no jokes about Alan Partridge - I ve heard them all) which is a 3.5mm / Emergency Call Operator setup and I purchased a UGREEN converter from Amazon (3.5mm to USB-C) for about £18, and it works tremendously well for call quality.

I want to try and monitor noise levels in a sealed environment. It's a project my daughter is doing, and we want to monitor the effects of various designs on reducing noise levels.
I can get an app that measures dB, and want the phone outside so we can see the levels, with the microphone inside in a fixed position.

You can get a decibel meter for about £20 on Amazon...

but since this is a school project, and it's not about accuracy, more about "which of A or B are louder" - then any microphone should do. Do you have any earpods in the house at all? They might be wired/bluetooth/anything, but chances are they have a microphone on them.

Wireless earpods/airpods could be very effective as you can put them anywhere in your experiment.

I looked at a cheap dB meter, but they are too big to fit inside, and ones with microphone/probes that are detachable seem insanely expensive.
