'''Xreal Air 2 Ultra''' is an [[augmented reality]] [[head-mounted display]] released in 2024.
The '''XREAL Air 2 Ultra''' is a consumer [[augmented reality]] [[smart glasses]] with spatial computing capabilities, developed by [[XREAL]] and announced at CES 2024 in Las Vegas. Released in March 2024 at $699, it is the first XREAL glasses to feature true 6DoF spatial tracking via dual 3D environment sensors with computer vision, enabling spatial computing experiences previously only available on devices like the [[Apple Vision Pro]]. The Air 2 Ultra adds hand tracking, electrochromic dimming, and a wider 52° field of view to the Air 2 platform.

XREAL unveiled the Air 2 Ultra at CES 2024 on January 7, 2024, positioning it as "the world's most advanced lightweight spatial computing glasses for developers." The device was marketed as an affordable alternative to the [[Apple Vision Pro]] ($3,499) and [[Meta Quest 3]], offering similar spatial computing capabilities at a fraction of the price.<ref name="tomsguide">{{cite web |url=https://www.tomsguide.com/news/xreal-air-2-ultra-ces-2024 |title=XREAL's new AR glasses are Apple Vision Pro's worst nightmare — true spatial computing at a fraction of the cost |publisher=Tom's Guide |access-date=2025-01-07}}</ref>
 
Shipping began in March 2024 alongside the Unity-based NRSDK 2.2, which provides developers with improved hand tracking, gesture recognition, spatial anchors, and depth mesh capabilities. The device was initially focused on developers before broader consumer availability.<ref name="prnewswire">{{cite web |url=https://www.prnewswire.com/news-releases/xreal-jump-starts-the-future-of-affordable-full-featured-spatial-computing-announces-xreal-air-2-ultra-ar-glasses-302027771.html |title=XREAL Jump-Starts the Future of Affordable, Full-Featured Spatial Computing |publisher=PR Newswire |access-date=2025-01-07}}</ref>
