I want to be able to talk on the microphone of my Headset A and send that signal out to the earphones of my Headset B. Something similar to what I show you on the image below.
For that purpose, I bought the piece below, which I can place in between both (it requires some power) to achieve my goal.
It actually works but there is some noise on the output signal that I can easily hear on the earphones of Headset B. For example, when the room is in silent and even not talking, I can hear that noise.
Then, I was thinking to build or configure some mic (pre)amplifier or something similar that let me achieve my goal.
(I have to say that I'm not an expert on this field)
I got the following 3 pieces on Amazon because they claim they reduce the noise or something like that but I don't know if they are exactly what I'm looking for and how to configure them.
Noyito - 12V High-fidelity Microphone Pickup Module Noise Reduction Microphone Amplifier Board High Sensitivity Kit
Acxico - AD828 - Stereo Dynamic Microphone Preamplifier Board Pickup Module DC 3.8V-15V MIC Preamp Module
Koobook SSM2167 - Microphone Preamplifier Board Preamp COMP Compression Module DC 3V-5V
Could you please, let me know if I can use them to achieve my goal?
Or if you have in mind any other way to do that, could you please, let me know?
Thanks in advance!
