iFixit’s Meta Quest 3S teardown reveals a Quest 2 ‘hiding inside’

What if I told you the Meta Quest 3S is in some ways just a more powerful Quest 2 with color passthrough? "Yes, of course it is," someone who's read our coverage might say, but iFixit shows just how true that is in the teardown video it published today.

The first hint of that is the headset's Fresnel lenses, which iFixit's Shahram Mokhtari writes in a blog post are "100% compatible" with those used by the Quest 2. The headset has the older headset's IPD adjustment mechanism, as well; and it shares the same single LCD panel, rather than using one panel per eye, like the Meta Quest 3.

Legacy parts aside, iFixit found that the 3S uses two IR sensors for depth mapping instead of a single depth sensor. That "rare iterative improvement over the Quest 3" performed "exceptionally well in unlit spaces," Mokhtari writes in the blog. And of course, it uses the same Qualcomm Snapdragon XR2 SoC as the Quest 3, and works with Meta's newer Touch Plus controllers, which are sold separately.

As iFixit notes, none of this should be considered a bad thing. The changes make the headset cheaper - the Quest 3S costs $299.99, while the Quest 3 is $499.99. It also means that if those reused parts break, it's not hard to find replacements for them, since the Quest 2 has already been around for four years.
