You may not care, but social pressure is effects -most- people. If you think you look like a moron to everyone around you, you're much less likely to take part in something. If a "headset that makes it all disappear" is a Godsend...why haven't you already bought the various headsets currently available that could already do that and worn it on a flight? I imagine there are two reasons, it looks silly and because it has no brand value associated with it (like Apple), it looks -really- silly.
