Pretty standard accessories for a pair of premium FPV goggles. Along with the HDZero Goggle, you receive a barrel jack to XT60 power cable, firmware update cable, custom HDZero head strap, canvas carrying bag, lens cleaning cloth, two faceplates with different contour to suit varying head sizes, and the faceplate foam.

Bear in mind that some essentials aren’t included with the goggles, such as antennas and battery. Later in this review, you’ll find helpful accessory recommendations.

Key Features and Specifications

The HDZero Goggles feature 1080p micro OLED displays with 46-degree field of view, providing the best possible HDZero experience. They also offer an exceptional analog experience thanks to their advanced filtering for the analog signal and de-interlacer to make the analog signal look as good as possible when used with an analog receiver module.

What sets the HDZero FPV Goggles apart is their versatility. They are compatible with multiple video systems, including analog video, Walksnail Avatar system, and of course, HDZero. No other goggles offer such compatibility with so many video systems.

Another key advantage of HDZero is its fixed, ultra-low end-to-end latency. This is crucial for racers and Acro pilots who require split-second response times.

Another unique feature of the HDZero FPV Goggles is the combination of low latency and high frame rate experience. While other systems like DJI offer higher frame rates, they lack the fixed low latency that HDZero provides. This combination results in a smoother and more precise flying experience, making it an exciting product for FPV pilots. It can take advantage of the new 90fps camera, providing an even faster and smoother video feed.

Finally, the HDZero Goggles is open-source, this enables the community to develop new features and enhancements. Despite some users have expressed doubts about the goggles’ open-source claims, noting that the core video transmission system is closed source, the open-source ecosystem surrounding this product is expected to continue to improve over time.  The CAD files for the goggle shells are also available, users can 3D print and customize their goggles appearance as desired.

Specification:

  • HDZero Camera glass-to-goggle glass latency: <3ms
  • Adjust IPD range: 57-70mm
  • Adjustable focus range: +6 to -6 diopter
  • Full HD 1920x1080p 90fps OLED micro display
  • FOV: 46deg
  • Input voltage: 7V-25.2V

HDZero Nano 90FPS Camera

Along with the HDZero FPV Goggles, Divimath also released a new camera – the HDZero Nano 90fps Camera.

In my onion this is a game-changer for HDZero goggles users, as it’s designed specifically to work with the HDZero goggles and provide the lowest possible latency for FPV flying. The Nano 90FPS camera is capable of delivering 720p at 60fps or 540p at 90fps, which boasts an even lower latency than the fastest analog video! This is an exciting development for racing pilots who prioritize speed and performance over detail.

The 90FPS mode offers a flying experience that makes pilots feel more confident and in control of their drone. Although 540p 90fps mode comes with a reduction in image resolution compared to the standard 720p60fps mode, the enhanced control and flying experience may outweigh the decrease in image quality for some pilots. This gives HDZero a considerable competitive advantage for pilots in racing or aggressive freestyle flying.

Closer Look at the HDZero Goggles

The HDZero goggles are made with high-quality moldings and a satin white finish, giving them a sleek and professional look. The build quality and ergonomics feels solid, with minimal flex and no creaking when the casing is twisted.

The first thing you’ll notice is that the HDZero Goggle shares the same basic form factor as other popular FPV goggles like the FatShark HDO2 and Skyzone SKY04X, but the HDZero are slightly larger. Despite their size, they still fit comfortably in most FPV backpack or goggles cases, and are designed to be comfortable to wear for extended periods of time.

The control on the HDZero Goggle is simple, with a spinning dial on the top left that allows you to navigate through menu options and select them. On the top right, a single “Function” button acts as a shortcut button for common tasks, such as start/stopping DVR recording and changing the cooling fan speed. The only other control is the red power switch on the right side, which is a sliding switch rather than a traditional push button.

Hdzero Fpv Goggles Top

The HDZero Goggles have three sets of fans to prevent fogging and overheating, making them perfect for all weather conditions. The built-in DVR can record HDZero and analog input, but not the HDMI input.

On the bottom of the goggles, you will find the head tracker input, firmware update ports for VTX, HDMI output (for feeding external display or recording),  HDMI input, micro SD card slot, and a 3.5mm jack for AV input.

Focus and IPD adjustment knobs are also available on the bottom to suit your vision requirements: focus from +6 to -6 diopter, IPD from 57mm to 70mm. The IPD and focus adjustments work well, although there is no locking mechanism like DJI Goggles 2, so you might need to readjust them occasionally.

Navigating menus in HDZero FPV goggles has never been easier, thanks to the intuitive menus of the HDZero goggles. The menu system is clean and modern, and provides easy access to all the settings you need. The dial control is an improvement over the 5-way joystick commonly seen in other goggles. It’s quick and easy to use, allowing you to change settings quickly and without confusion. And with the button on top, you can quickly access commonly used features like starting and stopping DVR recording and changing fan speeds.

The menu options in the HDZero goggles are comprehensive, providing access to everything you need to configure your goggles, such as power management, recording options, fan control.

And with ExpressLRS backpack functionality, coordinating between the VTX in your drone and goggles is more efficient.

Image Quality and Performance

The HDZero FPV Goggles are equipped with 1920x1080p 90Hz OLED display panels with a 16:9 aspect ratio, the displays easily outclass those found in most of the competition. In 16:9, the field of view is 46 degree, but in 4:3 mode the FOV becomes smaller at around 38 degrees. The HDZero Goggle’s optics excel in color and image quality, with constrasty colors and sharp imagery across the frame. The OLED displays appear to be superior to those found in the Skyzone SKY04X, making the image almost feel like you are using a new camera with better color.

If you have been following the HDZero system, you should know it excels in low light performance, with the ability to capture a surprising amount of detail even at night without much light source. This feature is especially useful for indoor flying in dark environments.

Comfort

The HDZero goggles offers a snug fit with minimal light leaks.

The provided strap is wide, soft, and stretchy, while the foam on the inside is dense and comfortable. Two faceplates are provided, one for wider and one for narrower faces, ensure a comfortable fit for most users. The goggles’ weight is evenly distributed across the cheekbones, avoiding pressure on the nose bridge. Weighing around 360 grams, HDZero goggles are lighter than DJI Goggles V2 but heavier than some binocular analog goggles.

While the HDZero Goggle is larger and heavier than an analog-only goggle like the Skyzone 04X, the ergonomics and head strap help make it comfortable to wear. The goggles are surprisingly compact and lightweight, considering the amount of electronics packed inside.

Essential and Recommended Accessories

If you have recently purchased or are considering purchasing HDZero Goggles, you may be wondering which accessories will enhance your flying experience. I will cover some essential as well as useful accessories, such as antennas, batteries, analog modules, and HDMI cables

MicroSD Card

You will need a microSD card for your HDZero Goggle to record DVR of your flights as well as to update firmware on the goggle. Firmware updates is easy with the HDZero goggles: simply place the firmware file in the SD card inside the goggles, and use the menu to complete the update process. You can learn more about SD card in my tutorial, and what to buy.

Recommendation:

Antennas

As mentioned, no antennas are included, you have to get your own. Learn more about FPV antenna in this tutorial and what to get. Using 4 omni-directional antennas are generally ok for close range flying and it’s low profile. If you want more range and balanced performance, replace two of the stubbies with directional antennas. For ultra long range, consider using all directional antennas.

Batteries

The HDZero FPV goggles consume significant power (14.5W in HDZero mode), requiring a sizable battery for a decent runtime. They accept any 2-6S battery, making them versatile and compatible with many different types of battery. You can just use your flight packs, but I recommend getting a dedicated battery for your goggles. The Auline is great you can mount it in the headstrap.

A 2S 4800mAh battery back would last just under 2.5 hours.

Analog Module

One thing to note is that the HDZero goggles don’t come with an analog module bay adapter, but it has to be ordered separately if needed. Get it here: https://s.click.aliexpress.com/e/_DmnRE0H

They support both TBS Fusion and ImmersionRC Rapidfire modules (review). The TBS Fusion offers a better form fit and a lower price at $120 compared to RapidFire’s $160.

HDMI Capture Card

You can get output video to an external display using a cheap HDMI capture adapter and HDMI cable. You can view what’s in the goggles on a phone, PC or even a TV. This can be useful for spectators in the field. For android app, search for “USB Camera Pro” in Play.

Conclusion

How does HDZero Goggles Compare to DJI

While HDZero has its advantages, it’s still a niche product. Some users prefer alternatives like Walksnail or DJI for better image quality, penetration and interference handling. The HDZero goggles have been criticized for their appearance, resembling 3D-printed prototypes or toys, but they have received praise for their versatility, performance and ergonomics.

The FPV community recognizes that HDZero isn’t intended to compete directly with established brands like DJI. Instead, it serves as a viable alternative, particularly for racers and fast pilots who need lower latency. This distinction carves out a niche market for HDZero.

HDZero FPV Goggles have an edge over DJI, which offers high frame rates but higher and inconsistent latency. The low latency and high frame rate of HDZero deliver a flying experience that instills confidence and control in pilots.

In the FPV world, there is no one-size-fits-all solution. Some pilots prioritize low latency and more connected control feel, as seen in HDZero, while others value image quality and signal penetration as seen in DJI.

Still wondering what FPV system to get in 2023? Check out my analysis.

Is Investing in HDZero Goggles Worthwhile for Analog-Only Pilots?

HDZero offers performance and interference handling comparable to analog systems, but with superior picture quality. If you mostly use HDZero, it makes total sense to get the HDZero Goggles. When you fly anlaog, you will also benefit from their high-quality OLED display and built-in de-interlacer that may improve your analog signal. Also, the HDZero goggles are the ideal choice for pilots flying with Walksnail Avatar VRX, as they are the only goggles capable of 720p 100fps, while other analog goggles are limited to 60fps which increases latency.

If you already own a pair of high-end analog goggles like the Orqa FPV.ONE or SKY04X, switching to HDZero goggles for $600-$700 including module bay and tax etc, might not be worth it. However, for pilots who are currently flying analog on a cheap set of analog goggles, investing in the new HDZero goggles could be beneficial, especially if you plan to explore other technologies like HDZero and Walksnail Avatar.

If you only fly analog and swear you will never fly digital, I think the Skyzone SKY04X is still a cheaper viable alternative to the HDZero goggles, as many HDZero advantages, such as the 90fps screen and a lot of options in the menu don’t apply to analog. The Sky04X is also more compact and comes with a decent receiver module that saves you money. Another crucial distinction between the two goggles is the screen size. The SkyZone Sky04X has a 4:3 screen with a 46-degree field of view, while HDZero goggles have a 38-degree FOV in 4:3. When using a 4:3 analog camera, which is the most common aspect ratio, the Sky04X provides a larger, more immersive image than HDZero goggles.

To conclude my conclusion

In conclusion, the HDZero FPV Goggles show great promise in features, compatibility, design, user experience, and image quality. As an open-source product with potential for continuous improvements, they are an exciting development for FPV. The combination of HDZero goggles and the 90 FPS Nano camera offers a unique flying experience, making them a top choice for pilots seeking ultra-low latency.

It could be nice to mention estimated battery life in the recommended battery section.

Expand on estimated/possible battery life.

Sorry if this comes off as rude, I’m not good with words.

Hey mate thanks for the review, now I am using HDO and want to upgrade my fpv goggles, I am between HDO2, Five33 orqa, HDZero goggles and 04X. I am flying only analog for racing. and will not use hd system.
Can I not take advantage of 90fps screen when I use analog system on HDzero goggles ? If yes this is bad. I want to buy hdzero goggles but what is the advantage relative to hdo2 or 04x for analog system ? thanks <3

Unfortunately no, analog doesn’t do 90Hz so it won’t make a difference.
If you never gonna use HD system, might as well just get the Skyzone 04X which is way cheaper than the HDZero and work well.

If you were to you enter the FPV world with no investment or ties now (summer ’23), which system would you buy into?

I’m torn between hdzero and perhaps get a external walksnail module for one day for picture quality if I feel I want it, or just go for DJI 2 goggles with 03 Air’s?
