Insta360 X4 Air VS Insta360 X5

The most meaningful design difference between these two cameras is size and weight. The X4 Air weighs 165 g versus the X5's 200 g — a 35 g gap that, while it sounds modest on paper, translates to a noticeably lighter feel during extended handheld shooting, selfie-stick use, or when mounted on a helmet for hours. The X4 Air is also shorter (113.8 mm vs 124.5 mm) and occupies a smaller overall volume (193.69 cm³ vs 218.77 cm³), making it the more pocketable and travel-friendly option. Width is identical at 46 mm, and thickness differs only marginally (37 mm vs 38.2 mm), so the compactness advantage is primarily in height and mass.

Where the two cameras are evenly matched, they share a genuinely impressive shared baseline: both are rated waterproof to 15 m without a housing, operate in temperatures as low as -20 °C, include a touch screen, a built-in gyroscope, and an external memory slot. Neither offers a secondary or flip-out screen, so the usability experience in that regard is identical.

For the Design group, the X4 Air holds a clear edge for users who prioritize portability and minimal carry weight — particularly relevant for action and travel use cases. The X5's larger footprint is not a flaw per se, but it is the trade-off buyers should consciously accept when choosing it over the Air.

Connectivity is one area where choosing between these two cameras requires no deliberation — the spec sheets are identical across every data point. Both support Bluetooth 5.2, Wi-Fi, and USB Type-C, and both are compatible with Android and iOS for remote smartphone control. Bluetooth 5.2 is a modern, capable standard that ensures reliable pairing and stable low-latency control when using a phone as a remote viewfinder, which is a genuinely practical feature for 360° cameras where direct framing is inherently tricky.

Neither camera includes GPS or NFC. The absence of GPS is worth noting for action sport users who want location data embedded in their footage — both cameras would require an external GPS accessory or post-processing workarounds to achieve this. NFC's absence is a minor convenience trade-off but rarely a dealbreaker for this category. On the positive side, both offer first-party live streaming support, which keeps them viable for content creators who broadcast directly from the field without needing a phone as an intermediary encoder.

This group is a complete tie. There is no connectivity-based reason to favor one model over the other — any decision should rest entirely on the design, imaging, or battery differences covered in other spec groups.

Battery is where the gap between these two cameras becomes most consequential for real-world use. The X5 carries a 2400 mAh cell versus the X4 Air's 2010 mAh — a roughly 19% larger capacity — but the runtime difference is far more dramatic than that figure alone suggests. Rated battery life comes in at 3.08 hours for the X5 against just 1 hour for the X4 Air, meaning the X5 lasts more than three times as long on a single charge. For a 360° action camera, where swapping batteries mid-activity is often impractical, that gap is operationally significant.

A single hour of runtime on the X4 Air places it firmly in the ″shoot in short bursts and recharge often″ category. Users planning longer sessions — a hike, a ski run, a travel day — would need to carry multiple spare batteries to match what the X5 delivers out of the box. The X5's runtime, by contrast, is workable for most half-day outings without any battery management.

The X5 wins this group decisively. The combination of higher capacity and dramatically longer rated runtime gives it a substantial practical advantage, and this is arguably the most impactful functional difference between the two models covered across all spec groups so far.

Audio capabilities are identical between the two cameras, and the shared profile carries one notable limitation: neither the X4 Air nor the X5 offers a 3.5 mm audio jack or any external microphone input. Both rely exclusively on their built-in stereo microphones for audio capture. For casual use and general action footage, the onboard stereo setup is sufficient, but users who need cleaner dialogue, voiceover, or low-noise audio in wind-heavy environments will find both cameras equally constrained.

This is a complete tie — there are no audio-related grounds to prefer one model over the other. The decision here, as with connectivity, should be driven by the differences surfaced in other spec groups.

Optics is where the X5 pulls ahead most visibly on paper. Its dual-lens system resolves at 72 MP compared to the X4 Air's 29 MP — a 2.5× increase in raw pixel count that directly impacts how much detail is retained when reframing or cropping a 360° capture into a flat export. For content creators who frequently punch into their footage to create traditional-looking shots from 360° originals, higher resolution provides meaningful headroom. The X4 Air's 29 MP is workable but leaves less latitude for aggressive reframing, especially at larger output sizes.

The aperture difference runs in the opposite direction: the X4 Air's f/1.95 lens is marginally wider than the X5's f/2.0. A wider aperture allows slightly more light per frame, which can benefit low-light performance, though the difference between f/1.95 and f/2.0 is extremely small in practice and unlikely to be perceptible in most shooting conditions. Where both cameras genuinely share common ground is in their imaging architecture — both use BSI CMOS sensors, both support HDR, and both offer a full suite of manual controls including ISO, shutter speed, white balance, and exposure. Adjustable field of view is also present on each, adding compositional flexibility without needing third-party software.

The X5 holds a clear optics edge on the strength of its substantially higher resolution sensor. Unless the marginal aperture advantage of the X4 Air is a deciding factor for a very specific low-light use case, the X5's 72 MP output gives it meaningfully more imaging versatility for the majority of 360° workflows.

Nearly every videography specification is shared between these two cameras — both record at 3840 x 30 fps, both cap out at a 180 Mbps bitrate, and both offer phase-detection autofocus, continuous AF, AF tracking, horizon leveling, timelapse, a 24p cinema mode, and invisible selfie stick support. At this level of feature parity, the codec pipeline and shooting toolset will feel functionally identical in day-to-day use.

The single — but fundamental — differentiator is field of view. The X4 Air captures at 170°, while the X5 shoots a true 360°. This is not a subtle distinction. A 170° wide-angle is an extremely broad single-perspective capture, but it is still a fixed, forward-facing frame. A full 360° capture records the entire sphere simultaneously, enabling complete reframing in post, VR playback, and the invisible selfie stick effect that both cameras list as supported — though the X5's full spherical capture makes that feature considerably more versatile and immersive by nature.

The X5 has a decisive edge here for anyone whose primary intent is 360° content creation. The X4 Air's 170° mode positions it more as a wide-action camera than a true 360° device, which meaningfully changes its use case. Buyers should weigh this distinction carefully, as it arguably defines which product category each camera actually belongs to.
