But if the issue is that "you can't hear" because of the headphones, then that wouldn't work. Now we all know that if you are plugged into the Delta sound system, you will still hear all of the annoucements and we also know that if they are not plugged in then it couldn't possibly interfere with hearing. But the QCIIs don't interfere with hearing either.
