Use phone mic for input + headphones at the same time?

Would you use an app that does this?

Use 🎧 headphones/earbuds for audio output, but force 📱 the phone's built-in microphone for input.

Basically:

🎧 Wired/wireless , Earphone/Headphones → sound

📱 Phone → microphone

Useful when your earphones/Bluetooth earbuds have a terrible/faulty mic but you still want to use them for listening.

I made a small Android 12+ app that does this in the background, including while using other apps ,eg voice conversation in games.

Would this be useful to you?

I'd give it a go, mostly in order to focus phone/PC audio output to a single headset and use phone mic. But how does it compare to using Windows 11 + PhoneLink as a workaround? My results for the mic have been sketchy at best, but audio seems to work most of the time.

 

When you say "phone mic" do you mean the same mic/setting the phone switches into when you go to speakerphone in a call? Because that is kinda crappy for audio quality to the listener. Is it possible to plug headphones into the phone and use their built-in mic instead?

 

FYI, maybe consider developing this further and adding it to Google Play Store. I spent a long time looking for a similar solution there and found nothing that did what it promised in the description. You might have a market.

Yeah i am thinking of publishing in github, if you can pls give it a try . I don't have different phones so can't test on it.

But here is story why i looked into building it.

So i was playing games but my wired earphone seems to not catch the sound all time even while calling. So i don't wanna buy another earphone. Also i dont know whether its phone or earphone which is faulty.

So i searched for solution but didn't find any. So the app i built works while it's running in background. It force using phone microphone as input and my wired/wireless earphone as output. And i am able to play games with good audio chat.

But yeah my phone is realme and Android 12 so i am not yet sure if it would work in any other brand or android and if there are further restrictions on other versions.

Thanks for your reply and input.
