In God Friended Me, our hero is doing a live podcast while wagging his head back and forth, which would make his voice change sound character while making its level go up and down. After signing off, he hung his headphones up on the microphone, GUARANTEED to create feedback at some slightly sloppy moment.

Then again, on Empire (I think it was), they gently put the headphones down on the desk. The headphones were never closer than two feet from the mic except when on the head.
