I have a JBL Quantum 300 that has a boom flip up microphone that is extremely quiet so I have to preamp it by 20db to make my voice be heard. The problem is, when I do this the sound of the headphone can be clearly heard on the microphone. I have tried several different drivers, tried both the front panel and the back panel, multiple Windows installations, both 10 and 11 and multiple BIOS updates as well. The sound can also be heard if the microphone is flipped up (muted). The result is every time I'm in a call with someone, they can clearly hear everything on the computer even their own voices being played on my headphone. How can I mitigate this? I have EqAPO installed, is there any plugin/feature that can do Echo Cancellation?

My motherboard is an MSI Z370A-PRO

I develop acoustic echo cancellation algorithms for a living. if there is echo also when your mic is muted, that means that it is not really muted. This makes me think that probably your headphone is feeding back the headphones signal to the microphone, probably due to faulty circuits inside you headphones.

Since I don't have the money to buy new headphones. Is it possible to have something that does Echo Cancellation on Windows? Maybe something that creates a virtual microphone that hears for the output and "subtract" it from the mic's input?

the realtek audio driver should have it as an option in sound settings, atleast it did for my last few motherboards
