I remember doing live A/V broadcast and we had a similar setup for comms for the whole team - a hardware push to talk switch was amazing. Might have to invest in something similar for my home workstation too.
Yes, exactly that. I was in live production for some years, that's where I grew to like the simplicity / bullet proof nature of that style. It would be nice if a manufacturer would release a USB headset that allowed monitoring of ones own voice, and a hardware talk switch.
