Good. Can you imagine sitting next to someone talking loudly on their phone the entire flight? Now multiply that across an entire plane.
Yes, because on every flight I have ever flown I have never heard people talking loudly to each other over the plane engines, babies crying, children laughing or yelling, or people pushing the flight attendant button numerous times just to complain about something.
I've never had to use my noise cancelling headphones on a plane, ever.
