So you have two, one for you and one for your wife? What is it like watching a movie next to someone, with both of you wearing headsets?

I would have been much more likely to get one when I was unmarried, but now with a family it greatly reduces my use cases since I don't watch content alone (except when doing the dishes, when I am largely focused on the real world task in front of me).

Yes, my wife took the M2 version when I upgraded to the M5. We find it pretty great, and it really is not much different from having a huge personal theater. The headsets appear to display the content in perfect sync. When sharing content with someone in the same room, it does not render a persona or avatar as it does when using FaceTime (where users appear as floating heads and hands).
