 Yeah, I caught that part. It also says you can move a few inches away and not be able to hear it. As for the sound resolving "inside one's head," that's what happens with headphones, and a lot of people voluntarily use them. I think people will get used to this just like every other technology that comes along. It's not exactly thought control or anything like that.
