Start with the job you want a device to do, then make sense of the terminology and specifications.
Explainer
Start with what you want to do: hear an assistant, glance at information, watch a screen or enter a virtual space. Similar-looking glasses can require very different hardware.
Terminology guide
Plain-English definitions of XR, VR, AR, passthrough, 3DoF, 6DoF, FOV, IPD, DP Alt Mode and OpenXR, with practical questions to ask before buying.
Display explainer
Read per-eye resolution, pixels per degree, refresh rate and lens claims without mistaking a specification sheet for a hands-on result.
Verify the device, port and software route before adding accessories to your cart.
Compatibility guide
Check video output, power and the exact adapter before buying. This guide covers USB-C and Lightning phones, computers, handheld PCs, Switch models, PlayStation and Xbox.
Compatibility checklist
Check the game, headset, graphics output, software, network and controllers before treating a gaming PC as a complete VR setup.
Explainer
A familiar app name does not establish that your purchase, saved progress or multiplayer session transfers to another headset. Check each part separately.
Compare configurations and the equipment you already own, with dated price references.
Research-based comparison
Quest 3 changes the optics and adds storage, while both headsets use the same processor. The listed US price gap is $250 or $150, depending on which Quest 3S you compare.
Research-based buying guide
Quest 3S and PS VR2 lead to different shopping lists. Start with the hardware you already own, then leave room for games, tax and required connections.
Separate an advertised saving or future promise from what is included and documented.
Price reference and buying guide
Official listings for VITURE Pro 2, XREAL 1S and One Pro, with coupon exclusions, return conditions and a method for judging a discount.
Announcement checklist
Separate reservations, shipping targets, optional accessories and manufacturer demonstrations from a complete, available XR product.
