I'm a new Android phone user. I'm looking for a setting or an application that can route audio input to phone's microphone while a wired headset is connected to it, but keep the audio output to the headset. I have been searching for this in Setting but I think it is not available there. I have been also searching for the app that can do this, the search results recommend me an app named SoundAbout, but it doesn't do what I want, it's just routing audio output to phone's speaker while a wired headset is connected to it.

So is there any?

There is no system-wide setting for this, unfortunately. And apps that try to control audio routing are usually hacks that cause problems on their own.

But I have a hardware solution for you -- buy one of those splitter adaptors that convert 4-pin TRRS into 2 3-pin TRS, separating for headphones and microphone, and only plug the headphones jack into your phone. Look for something like this: https://www.amazon.com/StarTech-MUYHSFMM-Headset-Splitter-Adapter/dp/B0058DOWH6 (I'm not recommending this particular adapter, just showing how it should look like).


Use an app named Lesser AudioSwitch.

    Hi, could you edit and expand the answer to explain why and how the app solves the issue? As of current writing, it's unclear why readers should use this app.
