RayNeo Air Series Compared: Air 2s vs Air 3s vs Air 3s Pro vs Air 4 Pro

RayNeo’s Air line of display glasses has four models: Air 2s, Air 3s, Air 3s Pro, and Air 4 Pro. All four are external display glasses that need a USB-C video connection to a phone, laptop, tablet, or game console to show anything. That is the line’s defining trait, and it is what separates the Air series from RayNeo’s X3 Pro (a standalone glasses platform with a camera and a Gemini-based voice assistant) and the iO AI glasses (which have a monochrome MicroLED display but don’t work as a USB-C video screen).

The naming doesn’t climb neatly. At the time of writing, the Air 3s Pro costs $20 less than the Air 4 Pro, and the lowest-priced model, the Air 2s, is out of stock. A side-by-side table is more useful than reading four product pages one at a time.

The four models differ mainly in price, brightness, HDR, audio, and a few certification and compatibility details. Here is the comparison, followed by which one suits which buyer.

What’s Shared Across All Four

• Weight: every current Air model lists 76 grams
• Optical architecture: every model uses birdbath optics rather than the waveguide used on the X3 Pro
• Field of view: every model lists a 46-degree field of view and a virtual screen equivalent to roughly 201 inches viewed from about 6 meters away

On those axes the models match, so the choice comes down to brightness, HDR, audio, fit and adjustment, and the scenarios you’ll use them for.

Brightness Numbers

RayNeo states these brightness figures on each model’s current product page:

• Air 3s: 650 nits, labeled “to-eye brightness”
• Air 3s Pro: 1,200 nits, labeled “to-eye brightness”
• Air 4 Pro: 1,200 nits, with no measurement basis labeled
• Air 2s: 600 nits in the Key Specs overview and 5,000 nits in a marketing paragraph on the same page, with no stated basis for either

Because of the Air 2s inconsistency and the unlabeled Air 4 Pro basis, compare brightness cautiously. The Air 3s Pro’s 1,200 nits is explicitly labeled to-eye.

HDR and Audio

The Air 4 Pro is the model with HDR10 support and real-time SDR-to-HDR enhancement through its Vision 4000 chip, and its page lists quad speakers with Bang & Olufsen tuning. These are the differences most likely to matter for movies. HDR10 benefits only content mastered in HDR10 and a source that outputs it; the enhancement applies to standard content.

Resolution

• Air 2s and Air 3s: “1080p”
• Air 4 Pro: “Full HD”
• Air 3s Pro: 1920x1080 for 2D and 3840x1080 for a combined stereo frame in 3D mode (two panels, each still 1920x1080)

“1080p” and “Full HD” both typically mean 1920x1080, so the practical resolution is the same class across the line. For more on the 3D figure, see the Air 3s Pro resolution explainer, “RayNeo Air 3s Pro Display Resolution Explained: 1920x1080 (2D) and 3840x1080 (3D).”

TÜV Certification

The Air 3s, Air 3s Pro, and Air 4 Pro pages list TÜV SÜD certification for low blue light and flicker-free display performance. The Air 2s page doesn’t list it in its spec sheet; “TÜV” appears only in an image caption. A short note: the Air 3s Pro page describes itself as the “only” display glasses with this certification, while other Air pages list it too, so treat that wording as marketing language rather than a performance difference.

Tablet Compatibility

The Air 3s and Air 3s Pro pages name specific iPad models. The Air 2s page mentions “iPad” generally, and the Air 4 Pro lists a generic “Tablets” category. If you plan to use a specific iPad, check the model list on the Air 3s or Air 3s Pro page, and confirm with RayNeo for the others.

Prescription Lenses

All four Air models support prescription lens inserts, but the purchase path differs. The Air 2s option is sold through RayNeo’s own purchase page. The Air 3s, Air 3s Pro, and Air 4 Pro pages link to Lensology, RayNeo’s external optical partner, whose pricing and processing times vary by region. If prescription lenses are a must-have, budget extra time for that separate order.

Fit and Adjustability

All four models list some form of adjustable fit:

• Air 2s: 9-point FlexiFit system
• Air 3s Pro: 9-level temple adjustment with a 3-level nose pad system, plus a published front-to-rear weight distribution (46.7 percent front, 53.3 percent rear) and eyebox coverage (14x7mm, roughly 93 percent of IPD ranges)
• Air 4 Pro: 9-way adjustment system
• Air 3s: adjustment and weight-distribution detail not listed on the product page

The Air 3s Pro is the model with the most published fit detail. For more, see the Air 3s Pro fit guide, “RayNeo Air 3s Pro Fit and Weight Distribution.”

Connecting to Game Consoles

The glasses read a USB-C video signal, the same kind a modern phone or laptop sends over USB-C. Consoles that only output HDMI need an adapter.

These requirements are the same whichever Air model you pick. For setup steps and power details, see the guides “Connecting RayNeo AR Glasses to Xbox, PlayStation, and Steam Deck” and “Can RayNeo AR Glasses Connect to Nintendo Switch?”

Which Air Model Should You Buy

If budget is the deciding factor: the Air 2s is the cheapest at $159 (list $299), but RayNeo lists it as out of stock with no restock date, and its brightness figure is stated two different ways on its own page. Among models available to order, the Air 3s at $269 is the least expensive, and it lists the TÜV low blue light and flicker-free certification.

If a documented eye-comfort certification matters to you: the Air 3s, Air 3s Pro, and Air 4 Pro list TÜV SÜD certification. Among those, the Air 3s is the least expensive at $269.

If you want a 1,200-nit to-eye rating at a lower price: the Air 3s Pro lists 1,200 nits to-eye, 1920x1080 per eye for 2D and 3840x1080 for a combined 3D frame, a 9-level temple and 3-level nose pad adjustment, and a published eyebox, at $279.

If you want HDR and built-in audio: the Air 4 Pro at $299 matches the Air 3s Pro’s 1,200 nits figure and supports HDR10 and real-time SDR-to-HDR enhancement. Its audio specification names quad Bang & Olufsen-tuned speakers; that does not mean the other Air models lack built-in audio. RayNeo calls it the “World’s First HDR10 Display in AR Glasses,” a marketing claim rather than an independent ranking. The 200,000:1 contrast figure isn’t an Air 4 Pro exclusive: the Air 3s and Air 3s Pro list it too. HDR10 only helps content mastered that way and a source that outputs it.

If you want a camera, a built-in voice assistant, or AI features: the Air series is built as external display glasses. The X3 Pro is RayNeo’s model built around those features, and it’s worth comparing.

If you mainly want movie or game viewing with a wider field of view and spatial display modes: RayNeo’s GT series is built around that use case. The GT Max has a 59° field of view, wider than the 46° on every Air model; the GT matches the Air’s 46° and differs in features such as its spatial modes and screen-size presets. Compare them side by side rather than assuming a higher Air model covers the same ground.
