And yet... trying these out just doesn't seem to be a thing anywhere. I can walk into any tech store and see a non-working unit in a glass case, or if I'm lucky pick up a slightly sticky broken controller, but I can't try one out for 5 minutes to see if I like it.
I'd bet that Apple's headset will be announced with a store experience to go along with it. I'm sure it'll be by appointment only to begin with as they'll have many more people wanting to try it than who will want to buy, but I'm sure there will be a way to experience them before buying. The Apple Watch was effectively a new product category where people needed a new level of persuasion, and Apple had fitting appointments that were very well done, and Apple Stores have always been known for being primarily focused on using the products, even letting you try AirPods, so I can't imagine these will be stuck in a glass case.
