can someone tell me why not to get wireless headphones

Imagine this: There is a breaking news report of a murderer on the loose. The news anchor is about to say where he/she is currently. Suddenly, the is no more sound. Your headphones are dead! You scramble to change them, but it is too late. You hear the door crash and you are face to face with the murderer.

I mean, if you're willing to risk that, not much is wrong with wireless headphones.
