Controller for a headset with volume control for monitoring the microphone

I want to use a closed back headset with boom microphone for my VoiP calls using Google voice in Chrome.

Since the headset will block most of my voice I need to hear it. Preferably amplified enough so I don’t start raising my voice in order to hear myself.

I am looking for a hardware solution with actual buttons to turn. No delay either.

Any suggestions?
