Precisely. I prefer the AirPods Pro because they’re even smaller and are less visible. I use them because they’re mine blowingly convenient and nice. They’re one of those few products that really brings joy. I wear them constantly both on the go, and at home.
But why did so many end up on exactly that model, when there are so many other brands? Because they're vastly superior, or because we're social animals and seeing lots of other people wearing them signals that they're a safe bet and will keep you in the in-group?
My point here is that the visibility of them on others help drive the sales. "If so many wears them, they obviously can't be bad". For this headset, you will not get that same kind of influences from others.
I agree with the point that seeing people using AirPods serves as a sort of social endorsement of the product. (Which is fairly different from your original assertion that "The AirPods you see all the time is because wearing them is a fashion statement.") Though I think the much stronger endorsement comes from talking to people you know and trust. The problem with merely "ambient" signaling (as in, you see people wearing them on public transit, etc.) is that you don't know anything about the preferences of the people you see wearing them. I see (or at least used to see) lots of people wearing Beats too, but I only ever heard bad thing about them from people I know and trust and, therefore, never considered trying a pair.
Vision Pro may not benefit from the latter (weaker) form of social endorsement, but it should be able to generate plenty of the former (stronger) kind.
