Apple says the Vision's device weight is 600–650 grams and Meta says its Quest 3 is 515 grams. The Vision is between 85-135 grams heavier despite there not being a battery on the part that you wear.

Anecdotally and in my experience, there have been many complaints about fatigue for the Quest, and I wonder if Apple will be able to get away with more premium materials in the future versions. It seems like there will be a big tradeoff between adoption and the materials used.

Vision isn't out, but I am curious what V2 looks like and/or a version that optimizes to comfort.
