The Xreal Air 2 Ultra is a pair of tethered augmented reality glasses made by Xreal (formerly Nreal). Xreal announced it at CES 2024 on 7 January 2024 with a US$699 price, began selling it in March 2024 and, according to the company's April 2026 Hong Kong listing application, discontinued it in July 2025 after about 13,000 units had been sold.[1][2] In February 2026 Xreal announced the end of Air 2 Ultra sales and said after-sales service and technical support would continue.[3]
Unlike the Xreal Air 2 and Xreal Air 2 Pro, which only track head rotation, the Air 2 Ultra has two front-mounted 3D environment sensors that give it six degrees of freedom (6DoF) positional tracking, hand tracking, plane detection, image tracking, depth meshing and spatial anchors.[4][5] Xreal marketed it mainly to developers. It has no processor or battery of its own and runs from a phone, computer or the Xreal Beam Pro over a USB-C cable.[6] The glasses weigh about 80 g, use dual Sony micro-OLED displays at 1920 x 1080 per eye and have a 52-degree field of view.[7][5]
History and development
Nreal origins
Xreal was founded in 2017 and is headquartered in Beijing.[8] Its first glasses with outward-facing cameras and environment sensors were the Nreal Light, which Xreal's listing application dates to 2019 with a US$499 MSRP. The filing groups the Light, the Air 2 Ultra and the upcoming Project Aura as one product line, each generation built around world-sensing cameras: environmental perception in the Light, hand gesture recognition added in the Ultra, and standalone computing and AI planned for Aura.[2] UploadVR called the Air 2 Ultra "the official successor to the Nreal Light" when it was announced.[9]
Rebranding to Xreal
Nreal announced on 25 May 2023 that it was rebranding as XREAL. At the same time it widened its supported platforms beyond Android.[10]
Air series evolution
From 2022 the company also sold its Air line of media glasses, which mirror a connected device to a virtual screen; until the Ultra, Air glasses lacked positional tracking.[9] Xreal's listing application gives these launch dates and US MSRPs for the Air series:[2]
| Model | Launch | US MSRP | Tracking | Notes |
|---|---|---|---|---|
| Xreal Air | August 2022 | US$379 | 3DoF (rotation only) | First Air model[2][4] |
| Xreal Air 2 | September 2023 | US$399 | 3DoF (rotation only) | No camera[2][7] |
| Xreal Air 2 Pro | September 2023 | US$449 | 3DoF (rotation only) | Adds electrochromic dimming[2][7] |
| Xreal Air 2 Ultra | March 2024 | US$699 | 6DoF | Developer-oriented limited edition with environment sensors and hand tracking; discontinued July 2025[2] |
CES 2024 announcement
Xreal unveiled the Air 2 Ultra in Las Vegas on 7 January 2024, in connection with CES 2024, and opened pre-orders the same day at US$699 with shipments expected in March 2024. Owners of the Nreal Light were offered US$100 off a pre-order.[1] UploadVR reported pre-orders in the United States, the United Kingdom, Germany, France, Italy, the Netherlands, Czechia, Japan, South Korea and China.[9] In Japan, pre-orders opened on 8 January 2024 (Japan time) at 99,800 yen including tax.[11]
At its CES booth (Central Hall #15060) Xreal showed "The Spatial Life", a demo that placed 2D apps and widgets around the wearer in 3D, and introduced the Mirage Shard Tracking Kit, a set of physical pieces that developers could use as tactile controls for virtual interfaces.[1] Engadget described the pieces as "AR cardboard discs" that toggled between work and casual profiles, and Windows Central later described them as colored cardboard and magnet pucks with different shapes.[12][13]
Market positioning
Xreal's announcement described the Air 2 Ultra as "an affordable alternative to competing devices, including Apple Vision Pro and Meta Quest 3", and said its 42 pixels per degree was "expected to be higher than Apple Vision Pro".[1] Press coverage questioned the comparison. TechRadar noted that, unlike those headsets, the glasses are not a standalone product,[14] and Engadget wrote that only the Apple Vision Pro and VR headsets could offer a "completely immersive experience".[12] In January 2024, Xreal CEO Chi Xu linked a new funding round to the launch of the Air 2 Ultra "in the spring".[8]
Shipping, discontinuation and end of sales
Xreal's listing application states that the Air 2 Ultra launched in March 2024 as a "limited-edition developer-oriented product" with an MSRP of US$699, that it was discontinued in July 2025, and that about 13,000 units were sold during the track record period covered by the filing.[2] In March 2024 MoguLive reported that orders placed by 31 March would ship by the end of May, which it attributed to a rush of orders from around the world.[15] On 27 February 2026 MoguLive reported that Xreal had announced the end of Air 2 Ultra sales, with after-sales service and product and technical support continuing under Xreal's warranty and support policies.[3]
Design philosophy
Glasses form factor
The Air 2 Ultra keeps the wayfarer-style shape of the Air series. Xreal gives its weight as about 80 g excluding the cable and its folded size as 148.5 mm x 48 mm x 60 mm.[7][1] That is slightly heavier than the 75 g Air 2 Pro, a difference Engadget attributed to the extra tracking hardware.[12] There is no bulky headband or visor; the glasses carry no battery and no computing chip, so all processing happens on the connected device.[6]
Titanium construction
The frame is titanium. Xreal called its "titanium ring frame" a first for the AR glasses industry.[1]
Adjustable fit system
The glasses have temples with three adjustment positions and come with three nose pad sizes (S, M and L). Xreal's specification also lists a detachable prescription lens frame for custom corrective lenses.[5][1]
Electrochromic dimming
Like the Air 2 Pro, the Ultra has electrochromic dimming on the front lenses. Xreal's specification lists three dimming levels, cycled with a single click of the multi-function key; a double click turns the display on or off.[5] MoguLive described the range as running from a see-through AR mode, where the background and virtual objects are both visible, to a mode with the background blacked out for focusing on a virtual screen.[11] In its CES hands-on, Engadget described the dimming as offering two shade levels.[12]
Display technology
Sony micro-OLED panels
The Air 2 Ultra uses two micro-OLED panels made by Sony Semiconductor Solutions, 0.68 inches across, each showing 1920 x 1080 pixels.[3] They run at up to 120 Hz in 2D mode and up to 90 Hz in 3D mode. Brightness is adjustable from 30 to 500 nits in 2D mode and from 20 to 250 nits in 3D mode.[5] The light reaches the eyes through a birdbath optical engine.[2]
| Display property | Value | Source |
|---|---|---|
| Panel | Dual Sony micro-OLED, 0.68-inch | [3][5] |
| Resolution | 1920 x 1080 per eye | [7] |
| Field of view | 52 degrees (Xreal figure); 45 x 25 degrees horizontal by vertical (UploadVR) | [7][9] |
| Angular resolution | 42 pixels per degree (Xreal figure) | [1] |
| Refresh rate | Up to 120 Hz (2D), up to 90 Hz (3D) | [5] |
| Brightness | 30-500 nits (2D), 20-250 nits (3D) | [5] |
| Optics | Birdbath | [2] |
Field of view
At 52 degrees the field of view is wider than the 46 degrees of the Air, Air 2 and Air 2 Pro.[7] UploadVR put the Ultra's field of view at 45 by 25 degrees, against 40 by 22 degrees for the other Air glasses, and noted that this is far narrower than the roughly 100-degree views of passthrough headsets such as the Meta Quest 3, so virtual objects are often only partly visible.[9]
Virtual screen size
Xreal says the glasses can show a 2D virtual screen equivalent to 154 inches viewed from 13 feet (about 4 m).[1]
Color accuracy and certification
Xreal states that every pair is TÜV Rheinland certified for Color Accuracy, Eye Comfort, Low Blue Light and Flicker Free use, and that the glasses exceed ISO standards for image quality and viewing comfort.[1]
Spatial tracking
6DoF inside-out tracking
The Ultra's main difference from the rest of the Air series is positional tracking. Its two environment sensors use computer vision for simultaneous localization and mapping to work out the wearer's position in 3D space, with no external sensors or base stations.[1] With a supported device, Xreal's SDK exposes 6DoF head tracking, plane tracking, image tracking, hand tracking, depth meshing and spatial anchors on the Ultra; on the Air, Air 2 and Air 2 Pro, which have no cameras, only rotational (3DoF) tracking is available.[4] UploadVR noted that the Nreal Light could only detect flat planes such as floors and tables, while the Ultra can generate a 3D mesh of a room, as Meta Quest 3 and Magic Leap 2 can.[9] Xreal's listing application gives a motion-to-photon latency of 20-30 ms for both the Light and the Ultra, compared with 3 ms for Project Aura.[2]
Dual 3D cameras
The two sensors sit at the outer corners of the frame, in the rim just above the lenses.[6][11] Xreal's developer documentation describes them as grayscale cameras; the Ultra has no RGB camera.[7] Windows Central reported that the sensors are only for depth and spatial mapping, not world-facing color capture,[13] and MoguLive noted that video recording and photo capture were not supported.[15] Xreal said the sensors were the smallest on the market at launch and would enable hand tracking, 3D mesh creation and semantic scene understanding.[1] Windows Central also observed that the sensors cover a much wider area than the displays, so the wearer can interact without looking at their hands.[13]
Comparison to Air 2 and Air 2 Pro
Xreal's SDK documentation lists these differences between the camera-less Air glasses and the Ultra:[4][7]
| Feature | Air / Air 2 / Air 2 Pro | Air 2 Ultra |
|---|---|---|
| Rotational tracking | Yes | Yes |
| Positional tracking | No (3DoF) | Yes (6DoF) |
| Plane tracking | No | Yes |
| Image tracking | No | Yes |
| Hand tracking | No | Yes |
| Depth mesh | No | Yes |
| Spatial anchor | No | Yes |
| Grayscale camera | No | Yes |
| Field of view | 46 degrees | 52 degrees |
| Weight (excluding cable) | About 77 g (Air), 72 g (Air 2), 75 g (Air 2 Pro) | About 80 g |
Hand tracking
Gesture-based interaction
Hand tracking uses the same two sensors. Xreal said the glasses would ship together with NRSDK 2.2, which added improved hand tracking and hand gesture recognition.[1] In Engadget's CES demo, the hand skeletons drawn over the reviewer's hands looked correct, but pinching a color slider often landed on the wrong value and interaction with the cardboard discs was laggy at times.[12] Tom's Guide found tracking "practically flawless" with palms facing up but said hands often disappeared when flipped over, and listed unreliable hand tracking as a drawback.[16] MoguLive's January 2024 hands-on reported dramatically improved hand-tracking accuracy and stable finger-based operation in its demo, while its March 2024 review said the downward-angled sensors only recognized hands once the arms were raised to some degree.[11][15]
Input and interaction
Multiple input modes
Apps on the Ultra can be controlled with hand tracking or with the connected device; in Xreal's SDK the phone acts as a 3DoF controller with a customizable on-screen controller UI.[4] On the glasses themselves are a multi-function key (dimming and display on/off) and an up/down button.[5] Xreal's CES announcement described "The Spatial Life" demo as controlled by "a user's eyes, hands, and voice".[1]
Xreal Beam and Beam Pro compatibility
At launch, Xreal listed the original Xreal Beam among compatible devices for 3DoF screen mirroring.[5] MoguLive noted that the optional Beam adds HDMI input, so game consoles such as the Nintendo Switch can be connected.[15] Xreal had said at CES that it was developing a dedicated computing unit for users without a supported phone.[9][12] On 18 June 2024, at AWE 2024, Xreal launched the Xreal Beam Pro, an Android handheld for its glasses. Xreal said the Beam Pro, running NebulaOS, gives the Air 2 Ultra a 6DoF environment out of the box, while the Air, Air 2 and Air 2 Pro get a 3DoF environment.[17]
Audio system
Directional speakers
The glasses have two built-in stereo speakers with sound leakage reduction.[5] Xreal describes the audio as "cinematic-grade" and directional, reducing sound dispersion for privacy.[1] Tom's Guide found the volume dependable but the sound "pretty tinny".[16]
Microphone array
Connectivity
USB-C DisplayPort Alt Mode
The glasses connect through a single USB-C cable using DisplayPort Alt Mode, which carries video and power from the host device.[5][14]
Device compatibility
Compatibility is split between screen mirroring, which works like the other Air glasses, and 6DoF "spatial computing", which needs specific hardware.[11]
| Use | Supported hosts | Source |
|---|---|---|
| Screen mirroring | USB-C video output devices, HDMI output devices, iPhone, Android, MacBook, Steam Deck, ROG Ally, Windows PC, Xreal Beam (3DoF), Nebula for Mac beta | [5] |
| 6DoF spatial computing at launch (January 2024) | Samsung Galaxy S22 and S23 with Snapdragon processors (One UI 5.1 or 6.0); the Exynos Galaxy S22 sold in Europe was not supported | [5][9] |
| 6DoF environment from June 2024 | Xreal Beam Pro running NebulaOS | [17] |
| Xreal SDK phone support (current documentation) | Beam Pro, plus Samsung Galaxy S24 (SM-S9210, Android 14) and Galaxy S25 (SM-S931U, Android 15) | [4] |
Xreal's SDK documentation says that from NRSDK 2.3.0 it reduced the list of supported phones to concentrate on the Beam Pro and Samsung flagship models.[4]
Nebula software
Xreal's Nebula launcher, for Android, Mac and Windows, was included with the glasses.[1] Xreal's listing application names NebulaOS as the Ultra's operating system.[2]
Spatial video
Xreal said the Air 2 series, including the Ultra, can play spatial video recorded on an iPhone 15 Pro once a third-party iPhone app has converted it to side-by-side format.[1] TechRadar noted that this conversion step was similar to how spatial video is watched on a Meta Quest 3.[14]
Use cases
Developer platform
Xreal called the Air 2 Ultra "a total package for developers" and said it would ship with NRSDK 2.2, which is built on Unity and added depth mesh with semantic labeling so that virtual objects can interact with real surfaces.[1] UploadVR reported Xreal's position that the Ultra was mainly for developers because there would be little AR content at launch, and that it was meant for indoor use rather than the outdoor use expected of future AR glasses.[9] Trusted Reviews reported that Xreal planned an "Xreal AR Lab" to make development more accessible.[6] Xreal's listing application states that the Ultra was intended to let developers "build and test applications with more natural interaction methods".[2]
Media and productivity
Without spatial apps, the Ultra works like the cheaper Air glasses as a private external display. Windows Central wrote that without an app ecosystem it is "functionally identical to the far cheaper Air 2 Pro",[13] and Tom's Guide made the same point for general consumers.[16] Reviewers used it to watch films with added 3D effects, view a laptop or Steam Deck screen, and try demos with virtual desktops, messaging windows and a personal 3D cinema.[6][12][16]
Games
Tom's Guide and Windows Central tried an early prototype of Landing Party by Monsarrat, an AR game in which players walk around a space to reach objectives and fight aliens.[18][13] Windows Central also played a tabletop tower defense demo controlled with the hands.[13]
Research use
A December 2025 bioRxiv preprint (not peer reviewed) by researchers at the University of California, Davis used the Air 2 Ultra connected to a Beam Pro to test AR-guided annotation on a hologram of a cadaver dog head, with a modeled oral tumor as the surgical scenario. In the distance task, completed by 22 veterinary residents and specialists, mean distance error was 2.73 mm when targets were shown directly on the hologram versus 3.42 mm when participants memorized them from a computer screen.[19]
Prescription lens support
Xreal's specification lists a detachable prescription lens frame, into which custom corrective lenses can be fitted.[5] See prescription lens inserts for the general approach used by AR glasses.
Reception
Coverage was mostly hands-on impressions rather than full reviews. Tom's Guide reviewer Jason England named it one of his favorite gadgets of CES 2024, praising the display, 6DoF tracking and comfort while calling the US$699 price "steep"; its early verdict described the glasses as "a meeting point between the capabilities of a VR headset, and the portability and lightweight comfort of AR glasses".[16] Engadget found room tracking smooth as the reviewer walked around but reported a demo crash on an Oppo Find X5 phone that grew warm, concluding that performance "is only as good as the computational device it's attached to".[12] Trusted Reviews listed the lack of a battery and of a computing chip, and software that needed more polish, as drawbacks.[6] TechRadar doubted the Vision Pro comparison because the glasses are not standalone and, at announcement, the only devices listed for spatial computing were the Galaxy S22 and S23 and a promised custom computing unit.[14] Tom's Guide's Alex Wawro wrote that the Ultra gave him "the best experience I've had yet" among AR glasses he had demoed over a decade, though the game demos were "a little janky".[18] MoguLive's March 2024 review noted a narrower field of view than mixed reality headsets but sharp text, and hoped firmware updates would improve hand tracking.[15]
| Outlet | Date | Type | Summary |
|---|---|---|---|
| Engadget | 11 January 2024 | CES hands-on | Smooth room tracking; pinch input and disc interaction unreliable; demo phone crashed once[12] |
| Trusted Reviews | 12 January 2024 | First impressions | Bright display, easy-to-read text; needs an external device for power and compute[6] |
| Tom's Guide | 14 January 2024 | Hands-on review | Pros: display, 6DoF, comfort; cons: US$699 price, hand tracking unreliable at times[16] |
| MoguLive | 27 March 2024 | Review | Wider view than Air 2 / Air 2 Pro; hand tracking needs raised arms[15] |
| Windows Central | 19 April 2024 | Hands-on | Interactive demos impressive; little benefit over the Air 2 Pro without apps[13] |
Comparison to competitors
vs. Apple Vision Pro
Xreal positioned the Ultra against the Apple Vision Pro, which was priced at US$3,499.[1][14] The products differ in kind: the Vision Pro is a standalone headset, while the Ultra is a tethered pair of optical see-through glasses with no processor or battery.[14][6] Xreal claimed its 42 pixels per degree would be higher than the Vision Pro's.[1] Android Central noted that the Ultra, at 80 g, is about 30 g heavier than Ray-Ban Meta smart glasses but far lighter than a mixed reality headset.[20]
vs. Consumer AR glasses
Road to VR described the earlier Air 2 and Air 2 Pro as closer to smart glasses than AR glasses because they lack positional tracking, and placed the Ultra in competition with room-sensing devices such as the Microsoft HoloLens 2, Magic Leap 2, Meta Quest 3 and Apple Vision Pro.[5]
Successors
Xreal's later glasses, the Xreal One and Xreal One Pro, have the company's X1 chip and 3DoF tracking in the glasses; Xreal's SDK documentation lists 6DoF head tracking for the One series only with a detachable RGB camera accessory, and none of the Ultra's plane, image or hand tracking, depth mesh or spatial anchor features.[7][4] In its listing application Xreal places Project Aura, developed with Google for Android XR, as the next generation of the Light and Ultra line, with a 70-degree field of view, about 95 g on the eyewear unit and a separate computing puck.[2]
