I think for such prestigious event for players to display a certain level of respect is important. Which means, players got to know when to be on a headphone and when to remove their headphones. But i believe, as an audience or even royalties will understand the importance of player’s preparation before game. Like mentioned by some posts, if they really want to control “disrespectful behaviour” they have to state it in the rules. Afterall, everyone is waiting for the best performance from the best athlete in a prestigious event.
