This reeks of immaturity. Not since high school has the sentiment of "I'm wearing headphones to be left alone" been a popular or reasonable one. At least during those years, peers could look at you and make the mistake that you're so deep that music has more influence/meaning than the world around you. If this is, as I feel, an attempt to legitimize this kind of "signal" to other professionals who want to collaborate with you, I feel pretty sorry for the kid who's hosting this.

I can appreciate individuals who don't have the capacity to swap context throughout the day, but only when they can be mature enough to explain themselves to me like an adult; and I certainly don't need a visual accessory to que my interaction with them.
