Help Enable only mic in headset

[Android Question]

I want to use only the mic in the headset
I have tried Apps such as Soundabout but it allows you to disable the mic only in the headset while i want to disable the speaker in it
The real problem is that i want to record a voice through an external mic and to play that sound through a bluetooth speaker
when i connect a headset containing built-in mic the sound is played in the headphones only and not sent to the bluetooth speaker

Why use a headset at all then? The phone can record fine without a headset. Better even, since with a headset you only have one mic, while some phones have 2 mics for recording when not using a headset.

the user of the device needs to have his hands free while recording

Then put the phone down? You don't have to hold it while recording. Or buy a mic only plugin, without headset.
