The band around the seats is just a strap that holds the headphone piece in place. It's completely harmless except for some unexpected loud noises. It's like listening to an audio book. That being said, I don't go to the theatre to listen to an audio book. I have never wanted anything to end so badly. It's a neat gimmick but ten minutes of it was enough for me. The sound/headphone aspect added nothing to the incredibly boring story. Most people, including my friends, didn't seem to dislike it as much as I but no one was extremely enthusiastic about it.
