That’s something I noticed a while ago: all podcasters have those huge microphones in front of them - sometimes with a gigantic boom - that wouldn’t look out of place on 1950s TV. But unlike in the 1950s, they’re not trying to hide them, no no: the more visible, the bigger, the better.
I can’t figure out the point of that prop. If I did a podcast, I’d try to unclutter the shot myself.
I said clearest sound. Yes, Shure SM7B is widely considered to be among the best at that. If you’re producing an audio product then it makes zero sense to buy an inferior microphone just because it looks better. That’s entirely missing the point of the format.
