I regularly hear people on podcasts, radio, and tv who go on shows with shitty mics. I don't understand how. "I'm going on a national radio show. Maybe I should get a decent mic? Nah, screw it. I'll just sound like garbage." And no one behind the scenes on the show sends them a mic? Or at least tells them not to use airpods as their mic? Certainly there times when an interview is set up quickly. But I've heard entire 90+ minute podcasts where the guest was on a terrible mic.
