Internal/external microphone + external headset?

[littlebigman]

Hello,

As an alternative to a dedicated audio recorder, I'd like to use an Android smartphone to record interviews.

To check the audio in real time, is there a way to use the internal microphone and an external headset, or even some Y-shaped contraption that includes an external microphone and an external headset connected through the audio jack?

Thank you.

A splitter, TRRS plug to 2 TRS jacks, with one jack wired to the audio output, the other one wired to the audio input, would do the trick. I doubt that there's one out there set up like that - you'd have to buy a plug and 2 inline jacks and wire them up yourself. (The schematic for the Android headphone jack is all over the web.)
