Insta360 X4 Air: two-minute review
It’s been just over six months since the release of the Insta360 X5, which showed up bang on cue to replace the highly praised X4 from 2024. The TechRadar team loved both of these models, placing them amongst the best 360-degree cameras, and you’ll see quite a few of them around the office. Now, in what may feel like Christmas come early for 360 video devotees, Insta360 has released the X4 Air, a smaller and even more portable package designed to fill a gap in the market.
Viewing the X4 Air side-by-side with the X5 – or the X4 for that matter – there are some fairly noticeable differences. Firstly, given the name, it’s no surprise to find that the X4 Air is smaller and more lightweight. If the X4 could fit easily into your coat pocket, the X4 Air can find a home in the pocket of your jeans, making it possible to travel through busy locations and be ready to capture video on the go without being noticed.
Despite the shrunken proportions, the body of the X4 Air retains the solid feel of the X4, and I was confident that the camera would fare better than I would in the city center rainstorm I was caught in during my testing.
The camera is quick and easy to set up and use, even if you have limited experience with videography or 360 capture. The screen is a little fiddly to use, given its small size, but this can be remedied by pairing the X4 Air with your smartphone and using the feature-packed Insta360 app to control the camera remotely. All of the menus are easy to navigate, and I had the camera customized to my requirements in no time.
The dual sensors in the X4 Air are smaller than those in the X5, but larger than the 1/2-inch units on the X4. I was greatly impressed by the dynamic range and noise performance of these chips in high-contrast and low-light settings. Colors were still punchy and shadows clean, despite the X4 Air not having the PureVideo Mode seen on the X5. The 8K footage looked fantastic straight out of the camera, and reframing using the app or Insta360 Studio desktop software was quick and easy.
There might not be enough reasons for X4 users to switch to the X4 Air, but assessed by itself, the camera is a great 360 shooting machine that made me fall back in love with the format. If you’re an avid explorer, or even a pro videographer looking to capture some more exciting angles, the X4 Air is a solid choice.

Insta360 X4 Air: Price and availability
- Launched worldwide on October 28 2025
- Standard edition costs $399.99 / £359 / AU$639.99
- Starter Bundle available for $439 / £389 / AU$699.99
The Insta360 X4 Air was released on October 28 and is priced $399.99 / £359 / AU$639.99, which is quite a bit below the price of the X4 / X5 at launch ($499.99 / £499 and $549 / £519 respectively). Considering that the X4 Air is technically an update to the X4, this seems a fair price to pay for the larger sensor and access to the replacement lens system.
Beyond the standard bundle above, Insta360 is also offering the X4 Air in a Starter Bundle, which includes the camera, a 114cm Invisible Selfie Stick, Lens Cap, and an extra battery which, given the limited battery life, is definitely a useful backup. This option can be picked up for $439 / £389 / AU$699.99, which is good value to get you up and running.
Insta360 X4 Air: Design
- 45 x 112 x 35mm in size, 5.8oz / 165g in weight
- Waterproof to 49ft / 15m
- 2.5-inch screen, USB-C 3.0 input and microSD card slot
If you’ve used an Insta360 camera before, you’ll fall right into step with the X4 Air. It shares much of the design philosophy with its stablemates, just in a smaller package. Let’s not forget that the Insta360 X4 is by no means a large piece of equipment, so I was initially concerned that by minimizing the body further it would result in some impractical control layout compromises. However, the changes that have been made are sensible ones, and feel more like refinements of the X4’s layout than unappealing but necessary drawbacks.
The front of the X4 Air looks simple, and not unlike a compact smartphone, albeit with an oversized camera lens. The area is dominated by the 2.5-inch touchscreen, and below that a single round button that’s assigned to shutter triggering by default. This replaces the dual-control design of the X4 and X5, giving the X4 Air a more streamlined feel.
I actually think I prefer having one large shutter button in the bottom-center of the camera body to the X4’s smaller shutter control at the bottom-left. During testing, I found it easier to find and press the large button without looking, a minor advantage to many prospective users, perhaps, but as a regular street and travel photographer, being able to get a camera up and running immediately as I pull it out of its case is something I’ve come to appreciate greatly.

As you’d hope for in an action camera, the build quality is robust, and capable of withstanding a few knocks and scrapes. Despite the reduced weight, the X4 Air doesn’t feel noticeably flimsier than the X4, another area I was concerned about, although I suppose Insta360 could only change the construction integrity so far before the camera stopped being fit for purpose.
I really like the textured grip pattern adorning the sides of recent Insta360 cameras. It gives the impression of solidity, and makes them feel like true tools made for outdoor use. On paper, I know action cams are often waterproof, but I often still have trust issues with submerging a valuable piece of technology; the X4 Air will go a long way to easing your nerves if you’re like me.
Another major upgrade over the standard X4 is the replaceable lens system. New to the latest generation of Insta360 cameras, the ability to easily swap out a cracked or scratched lens for a new one yourself, without having to send the whole camera away for an off-site repair, saves both money and time. It’s a very neat concept that frees you to take a few more risks with your camera, placing it in some more extreme positions for exciting angles, for example, with less concern that you are about to write off your Insta360 completely. It’s a multi-step process that requires some practice to do confidently, but the additional $29.99 (£29.99) cost for a replacement kit is good value for the peace of mind it provides.
The X4 Air weighs exactly the same as an iPhone Air – surely no mistake on Insta360’s part from a marketing point of view. At 165g, it’s not going to add a perceptible amount of extra load to your camera bag, and can even be transported in a coat pocket with ease when heading out for a day of exploring. Due to its size, I found myself taking the X4 Air with me everywhere, on the off chance a shooting opportunity presented itself.
Insta360 X4 Air: Performance
- Quick focusing
- Intuitive reframing
- Disappointing 88-minute battery life
I was a little slow to embrace 360 video shooting, probably because I was put off by how fiddly I thought processing and editing footage would be (I’ve had some bad experiences creating virtual tours for assignments, which left me traumatized, obviously). Right from the off, working with the Insta360 X4 Air via the mobile app was a breeze, however. Once you go through the usual activation and connection processes, which require Bluetooth for two-way communication between your smartphone and the camera, you can use the phone screen to preview the scene in far more clarity than on the camera monitor.
It’s easy to pair your devices, and preview clips and images stored in the camera roll, while there’s also the option to download files to your phone for editing. It is possible to work on files stored on your memory card mounted in the X4 Air, but this can slow down processing considerably. The app interface is fairly user-friendly, although some of the more advanced functions could feel a bit overwhelming to beginners.
In use, the X4 Air is highly responsive, being quick to start up and begin shooting. The audible ‘beep’ as the camera boots up is quite loud out of the box, potentially drawing some unwanted attention in quieter environments such as a museum or church; you can adjust the volume once the camera is on, although even after I’d muted it the tone still sounded on startup, which maybe have been an issue with my sample unit.
The touchscreen is nicely sensitive, and I experienced little to no lag when swiping to reframe 360-degree footage while recording. Admittedly, the preview image isn’t the highest quality you can find on a camera; it looks comparatively low-resolution if you’re accustomed to using a recent phone screen or interchangeable lens camera. Equally, the small size means tapping icons on-screen is a challenge if, like me, you have hands that are on the large side. This is why I’d recommend using your X4 Air paired to a phone instead, where practical.

The stated battery life of 88 minutes isn’t especially impressive, so carrying multiple replacements is a good idea if you’re away from home for any length of time. The charging time is fast though, meaning it’s easy to top up on power during a short coffee break at a cafe using the supplied USB-C cable. In my review sample, I found the USB connection quite loose, and some jiggling was required to ensure stable charging.
I did notice the X4 Air’s body heated up quite rapidly, even when not recording. I liked that the screen switches off automatically when not in use, to save battery, but keeping the camera on and at the ready for shooting means it still gets warm in the hand. It’s nothing extreme, but I do wonder how the camera would perform over extended shooting times in hot environments.
The camera is quick to focus, although again I’d recommend using a connected phone screen for assessing critical sharpness. The on-camera screen is too small for you to be completely confident that you have the subject in focus, although with such a deep depth of field at this focal length and given the smaller sensor, you don’t have to worry too much about obvious back-focusing.
Insta360 X4 Air: Image quality
- New dual 1/1.8-inch sensors
- Can record 8K 30fps or 6K 50fps video or 72MP photos (360-degree)
- No PureVideo mode for low-light
With a sensor more than 1.6x smaller than the Insta360 X5’s, you would expect a tradeoff in absolute image quality. Smaller pixels are the necessary compromise that allows the X4 Air’s diminutive size, and if you buy one, you’re likely doing so because a manageable size and weight are your top priorities. Considering the compact proportions of the camera body, Insta360 has done well to optimize the internal engineering, and the sensor is actually larger than the chip used in the X4 by almost a millimeter.
I jumped in at the deep end when testing the X4 Air, taking it to the low-light conditions of a Christmas-themed market at a local garden center. Despite the limited ambient light, footage was clean and detailed. Straight out of the camera there was very little discernible noise in shadow areas, and the image seemed sharp, free from the excessive mushiness that is the tell-tale sign of harsh in-camera noise reduction. Colors were also vibrant without being unnatural.
I genuinely think the video was superior in this area to that from my older semi-professional APS-C format DSLR cameras, which either made colors flat and dull in high-ISO footage, or wildly overcompensated by making them glow like a Tim Burton movie. This clip was quickly edited in the Insta360 Studio desktop app, which comes supplied with royalty-free music for social media use.
The dynamic range was perfectly acceptable, and while highlights tended to clip quickly in high-contrast lighting, the X4 Air did a good job of capturing shadow detail. I loved that a Log mode is available: I-Log produces a much flatter profile, allowing for more advanced color grading during post-processing while retaining more shadow and highlight data. This worked well, and although Netflix is unlikely to certify the camera any time soon, it does open up a wealth of cinematic styling opportunities.
Meanwhile, the Active HDR mode and Adaptive Tone setting are highly effective at preserving highlights. It’s worth mentioning that HDR shooting isn’t possible above 30fps. The frame rate is also limited to 50fps rather than the higher 60p available on the X4.
Shooting outside in good light produced the best results. The automatic white balance system also copes well in direct sunlight, although taking full control over the color temperature is possible through the menu, giving you more consistency between clips. This gives 360 footage a truly immersive and life-like feel, perfect for capturing the essence of a location while traveling.
- Image quality score: 4.5/5

Should I buy the Insta360 X4 Air?
Buy it if…
You value portability above all else
There may not be much of a reason to switch from another recent Insta360 camera model, but if you regularly travel and want to be discreet in how you shoot, the X4 Air is a truly pocket-friendly video camera.
You need 8K video
Arguably, 8K is overkill for many users, but it does open up cropping and reframing possibilities. Getting 8K capability in such a portable package is great for high-end videography purposes on the go.
You’re new to 360 video
The reduced price point compared to the X4 and X5 means the X4 Air represents an affordable entry point into the Insta360 system. You get many of the same great features, but with less investment, making it a good choice to test the water and see if this type of videography is your thing.
Don’t buy it if…
You just bought an Insta360 X5
….unless you want both! While I wouldn’t necessarily say the X4 Air is worth changing to if you already own an X5, which is the higher-end model, you might still consider owning both if you’re a 360 fanatic and want a smaller backup body.
You want maximum image quality
While the image quality is impressive, the X5 has the larger sensor and benefits from PureVideo mode for low-light and night shooting. For professional use, you might value absolute image integrity over diminutive size.
Also consider
The top-of-the-range model in the Insta360 family, the X5 is larger but more powerful. It enables recording up to 5.7K at 60fps, and features dual 1/1.28-inch sensors with larger pixels and greater light-gathering capacity. It also features the newer PureVideo mode that’s missing on the X4 and X4 Air, providing superior performance under poor lighting. The build quality and control layout are familiar, but with the added benefit of a larger LCD.
Read our in-depth Insta360 X5 review
It was only a matter of time before DJI entered the 360 video market, and it debuts with an impressive offering. We immediately rated it highly during our review, most notably for its price, which undercuts Insta360 by quite a margin. Its square design won’t be to everyone’s taste, but the build quality is good, and you also get a generous 128GB of built-in storage.

How I tested the Insta360 X5
- I tested a full production model running release firmware over several days
- I use the camera both mounted on an invisible selfie stick and handheld
- I recorded videos in varying lighting conditions, both indoors and outside
Having reviewed action cameras on and off for several years, I went into this test with high expectations. I spent roughly a week using the Insta360 X4 Air alongside an X5 for the purposes of a comparison. I shot footage on both cameras under the same conditions to evaluate how each camera handled noise and tonal range, then examined both out-of-camera footage and color-graded I-Log clips to evaluate image quality.
