RayNeo Air 4 Pro

The Air 4 Pro is a screen, not a computer: two 0.6-inch Micro-OLED panels at 1920x1080 per eye, 120Hz, 1,200 nits, HDR10, a Vision 4000 chip built with Pixelworks, four Bang & Olufsen speakers, 76 grams. No camera, no microphone, no battery, and RayNeo's FAQ says its XR glasses take no wireless link. China got it on October 23, 2025 at 1,699 yuan; the world on February 27, 2026 at 299 dollars.

The six reviews agree on the good part and, more rarely, on the bad. IGN called it the better value among wearable displays at the price. Then blurry edges turn up in five of them, Gizmodo blames the nose pads and Notebookcheck names them in long sessions, Tom's Guide notes there is no IPD adjustment, Android Authority hit Pixels where HDR10 and 3D refuse to run, and Gizmodo and New Atlas both watched it drain the host.

For development, one honest difference from the rest of the Air line. The Vision 4000 is an image pipeline, not a platform you can target; no review mentions an SDK or sideloading; and RayNeo's portal did not render for our research, so this file keeps the SDK unknown, not closed.

RayNeo never published the field of view, and our research rejected both figures going around. Prescription comes through Lensology, a third party. It suits whoever has a host to spare, and not whoever wears it for hours or carries a Pixel.
