RayNeo Air 4 Pro AR glasses review: Now enhanced with HDR10 and enhanced audio

The RayNeo Air 4 Pro AR glasses have been upgraded with a new Vision 4000 image-processing chip supporting HDR10 and a four-speaker audio system developed with Bang & Olufsen. The design remains similar to the Air 3s Pro, with minor cosmetic changes. The addition of plastic light blockers addresses previous light bleed issues. The Air 4 Pro features MicroLED projectors, HDR10 support, and various physical controls for user convenience. While the visual improvements are subtle, the audio quality enhancements are noticeable, making the Air 4 Pro a competitive option in the AR glasses market at $299.
