Microphone headset input while phone speaker output

Hi,

I heard your product SoundAbout can have headset microphone input, and the mobile phone can set to speaker sound output. Is that possible?

Downloaded the free version, doesnt seem to be able to do it, do you have a trial for the pro version?

I would also like to know, I need a solution! Thanks!

This is the same thing I'm looking for. (Also would like Bluetooth mic input while phone speaker output.) Someone else wanted the exact opposite as us (see here: https://soundabout.forumotion.com/t333-input-through-speakerphone-microphone-output-through-headphones-jack) and I think the response from David (SoundAbout) answers our question too:

Unfortunately,  the Android audio policy manager selects audio input based on audio output.   This means that if the wired headset is plugged in and used, Android will use the wired headset microphone (if available).  If a wired headphone (no mic) is plugged in, then Android uses the phone's built-in microphone.

How dumb of Google! Any computer lets you select different devices for audio input and output. Why not Android?
