Immediately after every Apple product presentation the people attending the presentation can try out the product in an adjacent "demo area". Which means there are at least a thousand people who could have tried on the headphones already, including reporters for most major media.

I have become increasingly more suspicious to these things since the iwatch launch.

but fair enough, the macword guy probably attended the event and had a few minutes to test the buds.

If you're just looking at fit, a few minutes is enough to test them. They were tested in the demo area after the event. Sound quality given the noise in the demo area is one thing you wouldn't really be able to know, however.

I'm unlikely to get a new phone any time soon as my iPhone 5 is fine (aside from battery life), but I am interested in the AirPods, if I could actually know how well they fit.
