The tech is indeed amazing.

I had a pair of Audio-Technica over-the-ear headphones about 12 years ago I took with me when I worked on a cruise ship. One night, I had the headphones on and the curtain to my bunk closed. Crew rooms are *very* small and to my surprise, the orchestra’s standup bass player and trumpet player (my roommate) had been practicing for the last hour without me ever having a clue.
