I disagree with this. Pods in ears are essentially a "do not disturb" sign for most people. Being around people who regularly have the "do not disturb" sign feels neglecting. People who might initiate conversation don't know if they will even be heard if they try to talk, so why bother. I would rather be alone than in a room of people who are actively ignoring each other.
I dislike the NC pause because it often awkwardly unpauses when someone is replying to you. I just pop the earbuds out when I start talking. To me, speaking with earbuds in is rude, and I want to show the courtesy to the person I'm talking to that they have my attention.
