InfoTime's company probably doesn't require him to wear headphones. Just like the NFL doesn't require players to wear Bose.
Don't be pedantic and try to parse what I'm saying. We all know that they are telling them that when they are appearing at an NFL event, like before or after a game, that IF they want to wear headphones they have to be Bose.
That in no way negates my point that it is not "just a normal part of business" (which is the claim I was responding to) to dictate what products people use that are not even related to the work that they do.
I don't know of any companies that say that if you want to drink soda at work, it has to be Coke and you can't bring your Pepsi here (except maybe Coke).
