RayNeo Air 4 Pro: 30-second review

The RayNeo Air 4 Pro Batman Justice Edition are the latest iteration of the company's display glasses and quite a leap forward compared with the RayNeo Air 3S Pro’s that I looked at, at the beginning of the year.

This new iteration runs alongside the standard RayNeo Air 4 Pro but adds a little Batman branding to the package. The glasses arrive in a large collector's vault that will instantly appeal to any DC fan. The presentation of the special edition box is rather restrained rather than garish, with a large bat symbol on an otherwise all-black box. Inside are the glasses inside the usual protective case, just with the addition of the Batman symbol.

Like the box, the glasses themselves are equally discreet: there’s just a small Batman logo on the right arm alongside the Bang & Olufsen branding, otherwise in every other way they look almost identical to the standard Air 4 Pro. The real differentiator is tucked beneath a cardboard divider, which, once lifted away, reveals the clip-on Batman mask. This is a masquerade-style shade that snaps neatly onto the front of the glasses frame, helping to block out light and amusing anyone who may be watching you.

The mask itself is actually well designed and clips and unclips easily; it’s also incredibly light, so it adds little or no perceivable weight to your nose, and does something genuinely useful beyond the obvious fun. The glasses' lenses are slightly opaque, so that you can see a little of what is going on around you. Once the shade is in place, this essentially blocks ambient light far more effectively than the standard shade, making a more immersive experience in brighter environments. Sat still watching The Dark Knight through a MacBook Pro; the effect with the mask in place is impressive once your mind gets used to the little big screen effect.

Through the test, I ran the glasses on a MacBook Pro M1 Max, an iPhone 15 Pro, an iPad mini and the RayNeo Pocket TV device, and the setup was consistently straightforward. The glasses power on automatically when the USB-C cable connects, and the display mirrors immediately with no configuration required. The cable that connects the glasses to a host device runs from the back of the right arm, over your shoulder, to the device, and it becomes easy to ignore.

One of the headline features over previous models is HDR10. In practice, watching HDR content via Netflix and Apple TV on the MacBook, the improvement in shadow detail and mid-tone contrast is real, although subtle. The Vision 4000 chip's AI SDR-to-HDR upscaling adds to the visual crispness of most content. Neither transformation is dramatic. Together, however, they do boost the visual quality over earlier RayNeo glasses.

The Bang & Olufsen audio is a clear improvement, and through the test, I found that the standard mode delivered the best balanced, clear sound, and a decent volume that was definitely better than previous AR glasses. Whisper Mode is once again inaudible to anyone nearby, especially in crowded environments, making this a great solution for commuting, although probably not with the mask in place. Surround Mode is the only disappointment. The spatial effect is noticeable, but the volume drop makes it difficult to use unless you're in a quiet room.

One of the other features I was keen to try is the 2D-to-3D AI conversion. For personal video files shot on your phone, it is genuinely impressive, creating convincing depth that surprised me on the first render to show my dog walking in pretty effectively in 3D. For feature films and streaming content, things are a little more complicated. The AI processing doesn’t work on streamed content at all, and even with locally stored files, the processing seemed to hang on content that was too long. The RayNeo Pocket TV accessory, tested separately, enables standalone streaming via Google TV but similarly does not extend 3D processing to that content.

The RayNeo Air 4 Pros are a great set of display glasses which pack down to the size of a glasses case, enabling you to take them anywhere. If you’re travelling, then it’s a great way to take a decent large-format screen with you. The Batman Justice Edition shade is a bit of fun, so if you're a Batman fan, then these will be a great choice. For all others, the standard edition is, aside from the mask, identical.

RayNeo Air 4 Pro: Design & build

The Air 4 Pro are instantly recognisable as a pair of display glasses with that slightly bulkier design compared with a standard pair of glasses. However, the size and bulk are slowly reducing, and these are noticeably slimmer than earlier generations and rivals I've tested.

The build quality of the frame is all well-constructed and has a premium feel despite the relatively low price. Some of the notable signs that these are not standard sunglasses include the thicker-than-standard arms that have space to fit the electronics, speakers, and control buttons. This means that while these are getting slimmer, they are still very noticeable as something different.

One of the main concerns with any set of display glasses is weight and, therefore, how comfortable they will be when worn for extended viewing sessions. At just 76g, the glasses are genuinely lightweight, and wearing them through a full viewing of The Dark Knight produced only the temporary nose pressure you'd expect from any glasses worn continuously.

The nose pad does offer some adjustment if limited by the ability to move the pads in and out to change the screen distance from your eyes, which is a useful calibration tool. The one consistent note from testing, as with the Air 3s Pro, is that to get the screen in the right position required pushing the glasses slightly down the nose from the natural wearing position. I

The glasses are not self-contained and require a host device to stream content, in the same way as a monitor. Here, a USB-C cable exits from the back of the right arm and trails down to your connected device, be that a laptop, mobile phone or Pocket TV. The positioning of the cable is well thought through, essentially over the shoulder rather than dropping straight down, and after an initial positioning, you genuinely forget about it.

There is something more to this edition of the glasses over the standard with the Batman shade that clips to the front of the frame. Once installed, the slightly opaque lenses are screened off to black, and the size of the mask helps to block out more ambient light than the standard shade. While the shade works and is light, it still adds some weight to the unit, and is probably best left at home when using these on your daily commute.

RayNeo Air 4 Pro: Features

The Air 4 Pro features two 0.6-inch Micro-OLED screens, one 1080p per eye with a max brightness of 1,200 nits, 200,000:1 contrast and 98% DCI-P3 colour. This is essentially the same as the Air 3S Pro that I looked at a couple of months ago.

What this latest release adds is an all-new Vision 400 processor that brings, amongst other enhancements, HDR10 support, better colour mapping and contrast. The other big feature here is the Audio by Bang and Olufsen.

The Vision 4000 chip's enhancements reach right across the feature set, especially with the new AI processing that works in the background to boost the quality of the visuals. AI SDR-to-HDR upscaling is applied in real-time, so it’s one of those features that makes a big difference, but you don’t actually notice it, as it’s so integrated with the workings of the glasses.

The AI 2D-to-3D conversion is another major feature that requires the companion app to use. This is good, but it does seem to be in its early development. For personal video files shot on an iPhone and stored locally, the processing is genuinely impressive, with the depth separation being convincing, and the effect adds genuine visual interest to the footage.

One discrepancy on the site's description of the glasses that is worth noting is that six colour modes are listed: Standard, Game, Movie, Eye Protection, Professional, and Vision Boost, but the review unit had only three: Standard, Movie, and Eye Protection. Game, Professional, and Vision Boost modes were not present in the firmware version tested, but may well be added later. Standard and Eye Protection proved the most useful for general viewing; Movie mode warmed the image far too much for my liking.

The Bang & Olufsen audio partnership is genuinely a great addition with the four-speaker system. Standard mode supplies clear, balanced sound with good depth and enough volume for most environments. Whisper Mode is once again impressive, and sitting in a café, the people I was with were unable to hear any noise from the glasses until they put their heads up close.

One of the audio features that I was looking forward to trying was the Surround Mode, which introduces spatial quality to the audio.

Through the test, I tried the glasses with several devices and for all, the Plug-and-play compatibility was good with the iPhone 15 Pro, MacBook Pro M1 Max, and iPad mini, simply plugging in and being recognised without issue.

Navigation of the on-screen display is handled via a double-click of the left arm menu button to enter settings, volume buttons to scroll, and a single click to select. Switching between 2D and 3D requires a triple press of the volume rocker, followed by the RayNeo XR app to manage content. The control system works, but it takes a while for it to become intuitive.

RayNeo Air 4 Pro: Performance

The simplest way to get started with the Air 4 Pros is to simply plug them directly into the USB-C port at the bottom of your phone, laptop or other device that enables display out. Once the glasses are plugged in, they instantly become a virtual 201-inch screen or at least the illusion of one.

Initially, it does just look like two small screens in front of your eyes, but due to the close proximity and resolution, your brain quickly enables the illusion of the scale of the screen to settle in. Once that brain adjustment happens, the effect of the screens is impressive and makes an ideal option for watching back media.

One hope for these display glasses was that I would be able to use them as a wearable screen for the computer; however, at 1080p, the screen resolution is limited. There’s also the fact that you need to keep your head still as the lenses are fixed to the glasses, so every head movement sees the screens move, which is initially a little disorientating. Unlike VR glasses, there’s no image stabilisation, so the more stationary your head, the better the effect.

The way that these glasses work is that what you’re looking at is actually a projection of the screens, rather than directly at the screens themselves. This means that the lens part of the glasses, while dark like sunglasses, is opaque so that you can see what’s going on around you. However, the density of the shades is high, so while in bright conditions you can see in front of you, in shaded rooms they may as well be blacked out, and all you really see are shadows crossing the display.

As with previous editions, there is a plastic shade that clips to the front, helping to block the light and boost the screen visuals. However, these being the Batman edition, as well as the standard shade, there's also the Batman option. This mask is larger than the standard version and helps to illuminate even more light. The effect is good and really does have a dramatic effect on just how immersive the experience is.

The visuals are good, but then so were the visuals of the Air 3S Pro, which share a similar resolution and specification screens. However, with the new Vision 4000 processor, the visual quality gets a boost with HDR10 content, which displays brighter and with greater dynamic range.

In practice, HDR10 content viewed via Netflix and Apple TV on the MacBook Pro showed better shadow and highlight detail than the standard display, and the videos were slightly stronger in contrast and brightness. While there is an improvement, it is subtle, so if you’re expecting a huge difference, then you’ll be disappointed.

HDR content on the MacBook Pro via Netflix and Apple TV is a great place to check the full effect, although again limited by the 1080p resolution, which is apparent. The Dark Knight was used to test the visuals, primarily due to it being a Batman film, but it was also partly shot on IMAX film with extremely deliberate lighting. The effect was notable, but you would only notice it if you were looking for it.

Flicking through the glasses options, there’s a good amount of choice, and those looking to use this with a gaming console will be pleased to see the 120Hz refresh rate option. At 60Hz, action sequences showed a small amount of motion judder, although this is slightly masked by the 1080p resolution. Switching to 120Hz did enable smoother motion, and for gaming, you’d probably want to switch to this option; for standard TV and film, 60Hz will more than suffice.

One of the notable features of these glasses is the 1,200 nit peak brightness, and when these are coupled with the dark opaque lenses, you can view the screens in almost any lighting conditions. There is the usual shade in the box, but then, this being the Batman edition, there’s also the Batman mask that can be clipped to the front. This is probably not something that you would want to wear in and around the office or in public, but in the comfort of your own home, it is a bit of fun.

While the main aim of the Batman shade is to support the partnership with the Batman brand, the larger size of the shade compared with the standard version does help to block out a little more light and further adds to the immersive experience. Other than the visuals of the Batman mask, there really is little other benefit, and unless you’re a Batman fan, then it’s probably best to opt for the slightly cheaper standard version.

One of the other features that had stood out was the 3D potential, especially with these being Batman-branded. To access the 3D features, you can either use the App to view your own content or stereoscopic content by double-clicking the left and right rocker levers on the arms. I was hoping that with the Dark Knight having been shot for IMAX, or at least some of the scenes, would somehow be 3D optimised through the AI feature. Testing this feature with the glasses connected to the App and video content from my phone viewed through the app, the effect is impressive; oddly, still images once processed are less impressive. Having tested some smaller files, I decided to see if this near-realtime 3D enhancement of video was also possible for feature films and streaming content.

Unfortunately, I quickly established that this may be pushing the 3D AI conversion a little too far, and streamed content cannot be processed regardless of the source, and even the RayNeo Pocket TV accessory, which brings standalone Google TV streaming to the glasses, doesn’t add any 3D processing.

Looking at the colour options, and again there’s a good choice, and the effects are quite stark, and through this test I actually found the standard mode was the best for film, TV and other content. Switching to the movie option turned everything a little too yellow.

Another of the big features for these glasses is the audio partnership with Bang & Olufsen, and this is genuinely a good boost to the audio quality. Watching several episodes of Monarch and The Dark Knight through the MacBook Pro, the sound quality through Standard mode was impressive, comfortably better than laptop speakers and on a par with a decent set of over-ear headphones. Whisper Mode's ability, which impressed me in the past, once again manages to contain audio within the immediate vicinity. However, the surround sound option that I was looking forward to testing just seemed to run too quietly, and the only place that I could take full advantage was in a quiet room, and even then, the volume just felt a touch too quiet.

In the final part of the test, I tried using the glasses as a secondary display for the MacBook, and I found that for reviewing product manuals and reference material, it was workable. While for reading, the resolution is ok, and the larger area was good, again, you do need to keep your head still. Throughout the review, while these screens are good and the price well balanced, you still can’t escape that the screens are quite small compared with the latest VR headsets, and the fact that there’s no horizon steady or stabilisation will take a bit of getting used to.

Alongside the Air 4 Pros, I also took a look at the RayNeo Pocket TV accessory, tested as part of this review, and this worked incredibly well once set up as a standalone streaming device connected to the glasses via USB-C, and enables you to connect without a phone or laptop, as long as there’s a wifi connection.

• Performance: 4.5/5

RayNeo Air 4 Pro Batman Justice Edition: Final verdict

The RayNeo Air 4 Pro Batman Justice Edition display glasses are great fun if you’re a Batman fan and want something else for the collection. For everyone else, there’s the standard option of the Air 4 Pros, which are slightly cheaper.

If you strip away the fact that the shade is a Batman mask and you’re unlikely to wear it out in public, the effect when clipped to the front of the glasses, with the more extensive coverage over the shades, actually does block more light, so in a way, the mask is practical.

When it comes to the list of enhancements from the Air 3S Pro I looked at earlier in the year, while the screen resolutions remain much the same, the HDR10 display, Bang & Olufsen audio, and a 120Hz refresh rate do make these glasses and far better for media playback when you’re on the move.

The 3D conversion feature again offers great potential, and it works well on personal video footage, but at present, it cannot process streaming content, and even on compatible files, the effect varies depending on the content, but is genuinely impressive.

For DC fans, the Justice Edition is great fun. For everyone else, the standard Air 4 Pro offers identical performance, and at a slightly lower price.
