Q: DJI Goggles 3 vs N3: The £275 Mistake We See Every Week

Quick Answer

The DJI Goggles 3 (£499) and DJI Goggles N3 (£224) both use DJI's O4 video transmission, but they are not interchangeable. The Goggles 3 supports both O3 and O4 Air Units for custom builds. The N3 only works with O4. If you plan to build a custom FPV drone with an O3 Air Unit, only the Goggles 3 will work.

DJI Goggles 3 vs N3: What Nobody Tells You Before You Buy

We sell both sets of goggles, and the conversation at our counter almost always goes the same way. Someone picks up the DJI Goggles N3 because it's less than half the price of the Goggles 3, assuming the cheaper option does the same thing with a smaller screen. It doesn't. The difference is not just display quality. It's compatibility, and getting it wrong means the goggles will not connect to your drone.

Here is the spec that matters most: the Goggles 3 has dual micro-OLED displays running at 100Hz with 24ms latency on O4. The N3 uses a single 1080p LCD at 60Hz. Both look good in the air, but the Goggles 3 is noticeably sharper, especially for racing and freestyle where fast transitions expose the LCD's slower refresh.

The Compatibility Matrix: What Actually Connects

This is where most buyers get caught out. The N3 only talks to O4 devices: the DJI Avata 2, DJI Neo, and drones with an O4 or O4 Pro Air Unit fitted. The Goggles 3 supports all of those, plus the older O3 Air Unit, which is still one of the most popular video transmitters in custom FPV builds. DJI added O3 support to the Goggles 3 through a firmware update in mid-2024, so update yours before binding.

Neither set of goggles works with analogue video, Walksnail, HDZero, or OpenIPC. Browse our full range of FPV goggles and video systems if you need alternatives.

Custom FPV Builds: The Critical Difference

If you are building your own drone or buying a BNF with an O4 Pro Air Unit built in, either set of goggles will receive the video signal. The control link is separate: you can use ELRS with a Radiomaster or other radio, or pair the DJI FPV Remote Controller 3 directly. The goggles handle video only. Your radio handles control. They work independently.

The problem arises when you already own a drone with an O3 Air Unit, or you want to build with O3. The N3 cannot bind to an O3 Air Unit at all. No firmware update will fix this; it's a hardware limitation. Only the Goggles 3 supports both O3 and O4 Air Units.

For BNF drones with O4 Pro like the BetaFPV Pavo20 Pro II, both goggles work. Our recommendation for BNF buyers on a budget: the N3 is fine for ready-to-fly drones that ship with O4.

What We'd Actually Buy

For pilots who only fly DJI consumer drones (Avata 2, Neo) and have no plans to build custom FPV: the Goggles N3 is the practical choice at roughly half the price.

For anyone building custom drones, mixing O3 and O4 Air Units, or wanting the best image quality for freestyle: the Goggles 3 is the one to get. The dual OLED panels, O3 compatibility, and 100Hz refresh rate make it worth the premium. See our full FPV goggles buying guide for wider comparisons.

If you already own DJI Goggles V2: the Goggles 3 gives you O4 support and better image quality, but you lose backward compatibility with the original DJI FPV V1 system. See our DJI O4 Air Unit guide for the full breakdown.

FAQ

Q: Can I use DJI Goggles 3 or N3 with ELRS for control?

A: Yes. The goggles handle video only (O3 or O4 Air Unit). Your ELRS receiver and radio handle control independently. You do not need the DJI FPV Remote Controller 3 unless you want DJI's own control protocol.

Q: Will the DJI Goggles N3 ever support O3 Air Unit?

A: No. This is a hardware limitation of the N3's receiver. It cannot decode the O3 signal. Only the Goggles 3 supports both O3 and O4.

Q: Do I need to update firmware on DJI Goggles 3 for O3 support?

A: Yes. O3 support was added in a mid-2024 firmware update. Update through the DJI Fly app or DJI Assistant before binding.

Q: Which goggles are better for wearing glasses?

A: The N3 fits comfortably over prescription glasses. The Goggles 3 requires diopter inserts or contact lenses.
