Royole Moon review – the lowdown

I had the opportunity to try out the Royole Moon briefly while on my travels in the USA. But now we have been loaned the latest version for a more detailed review. To get an overall perspective on the product, we recommend that you read both reviews. This will give you the full picture.

What is the Royole Moon

The Royole Moon is a personal cinema or movie theater. You can use it to watch movies, television, videos, internet content and even a monitor for computer games. It can receive content from any device with an HDMI, USB or WiFi output and it can store 32 GB of data on the smartphone-sized box that powers it. In other words, the box does double duty as the power source and the data source.

It can also receive data via WiFi – and in fact is WiFi -ready. Indeed, when we first started using it, the first thing we did was go to settings and set it up for WiFi. It showed a list of WiFi accounts within range, we selected ours, entered the password and that was it. We were set up and ready to go.

From there we went to YouTube and proceeded to feast our eyes – and ears – on content to suit our eclectic taste. Music, comedy and live news from various sources.

But let’s break it down into elements.



The Royole Moon uses touch controls for navigation. After pressing the round button on the box to switch it on the headset, you control the unit almost entirely from the right headphone with swipes or slides of the fingers on the surface. The outer rim controls the volume and the inner circle controls the rest. Slide clockwise or anticlockwise round the outer rim to make it louder or quieter respectively. Swipe left, right up and down on the inner circle of the right headphone to move between icons on the screen. To start/stop the current content, you simply single tap on the inner circle. Double tap to go back to the previous screen or operation

Also, slide (rather than swipe) your finger along the inner circle when you are in browser mode on the internet. This moves the cursor, in much the same way as you would on a trackpad. But When you have to enter data on the virtual keyboard for the browser (or the mini-keyboard for YouTube) you must use the more awkward swiping method to move one letter at a time, whether sideways, up or down.

All of this is pretty much intuitive, and I more or less figured it out without reading the instruction manual, or even the quick start guide.

Well I say intuitive, but it was not all plain sailing. Because the swiping method (as distinct from the sliding method with a cursor) is actually quite awkward and easy to get wrong. This made it rather hard to enter letters when it came to making a specific selection on YouTube.

When you have to move a cursor one step at a time and then tap once (and only once) to select a letter, it is very easy to make a mistake and enter the wrong letter. And then, having to go to the back button to delete the erroneous letter, adds to the frustration. Then if you want to select the same letter twice and tap twice without pausing, the system thinks you have selected the go-back option and takes you to the previous screen or menu level!

In fact, it is fair to say that the single most frustrating experience with the Royole Moon is trying to correct entry errors and selection choices

Now obviously, you couldn’t have an actual touch keypad because you are cocooned inside a headset. However, they could have used the cursor and the sliding method, to enable the user to home in quickly on the relevant letter on a virtual keyboard, followed by a tap to select that letter. Hopefully. Royole will change it to this method in the future.


Eyepiece diopters

Now this is one of the cleverest features of the Royole Moon. Not everyone has the same sized head. Consequently, not everyone’s eyes are spaced equally apart. The Royole Moon makes allowance for this by enabling the eye pieces to be moved to the left or right, varying the distance between the pupils from 58 – 70 mm. You just press the button-dials gently in and slide them to the right positions for your eyes. I noticed that the one on the left was slightly stiffer to the touch than the one on the right. I don’t know if this is true of every model.

Ignoring the stiffness, however, I noticed a slight problem. If I had the eyepieces pushed close together, I could see the “screen” perfectly with no visible “division” between the two eye-views, but the corners of the screen (especially the lower corners) were truncated. This probably means I had the eyepieces too close together.

However, when I pushed the eyepieces further apart, while I could then see all four corners of the screen, I could also see two faint curved lines in the middle, separating the views, suggesting that the eyepieces were now too far apart. The best way to describe this is when you try to focus on something very close to your eyes and see the sides of your nose. A slightly better analogy might be when you are looking through binoculars, but do not press the eyepiece close to your eyes.

This leads to another point, that the headset doesn’t feel like it is close enough to the face. This is partly because of the weight. At times it tends to feel like it is slipping and one has to tighten it around the head to keep it in place.

In addition to being movable, the eyepieces have diopter dials that can be rotated to change the focus of each eyepiece separately between -7.0 (near-sighted) and +2.0 (far-sighted). This means most people can wear the RM without glasses! (And this is very important for maintaining a tight seal to keep out the ambient environment and make sure that the experience is truly immersive.)

I found that by shutting each eye and rotating the other, I could get the settings right. I have a slight problem related to my vision that made this a little harder. My left eye is slightly “lazy” in that it takes longer to change focus. So, when tried to set the focus right for left eye it was a little trickier as the eye took longer to settle down on what I was focusing on. Once I had it approximately right, I had to spend a few more seconds fine-tuning it to get it just right – and even then, I’m not entirely sure that I did.

But as I said, that’s a problem with my eyesight. I have exactly the same problem at the optometrist, when they narrow down the left-eye lens selection to a choice of two and then ask me which is sharper. I say, “can I try the other one again… okay, now the first… okay now the second one again…” You get the picture!

Viewing experience

Apart from the above problem of the truncated corners, the viewing experience was an absolute pleasure. The Royole Corporation describes the view as a virtual 800-inch screen. However, that is only meaningful in relation to your notional distance from that screen. And Royole doesn’t say what that notional distance is to justify the 800-inch screen size. I myself cannot put a figure on it either. But it felt a bit like sitting two-thirds of the way forward in the stalls of a large cinema with a wide, curved screen – plus the added “pleasure” of being in the middle of the row and, better still, of being the only customer!

In terms of numbers, we are talking about a 110° field of view – comparable to the best VR headsets currently on the market, but soon to be eclipsed (rumor has it) by a couple of VR headsets breaking the 200° FoV barrier. We’ll see if Royole rises to the challenge.

As mentioned, in order to be able to show 3D, the Moon has separate displays for each eye. Each display has a full 1080p resolution (i.e. 1920 x 1080). The contrast range is 10,000:1, the color is 24-bit RGB and the refresh rate is 60 Hz. This is easy on the eyes.

There is a button for switching the images between 2D and 3D button. However, the device can automatically detect whether the content is 2D or 3D. If you press the button to override the system’s choice you end up feeling like Clarence the cross-eyed lion. (Readers of a certain age will know what I’m talking about.)


Listening experience

The unit includes noise-cancelling headphones that offer very good and faithful sound reproduction. While they did not completely cancel out ambient noise, they did such a good job that within a short time there was a feeling of being completely secluded in the world of whatever content we were watching and/or listening to. And of course, adjusting the volume was dead easy, with a simple slide of the finger clockwise or counterclockwise around the outer rim of the right headphone.

There is a big range of content available for the Royole Moon. Any device with an HDMI or USB output can supply content. You can upload videos from a computer to the device. And that means you can watch DVDs and Blu-ray disks via your computer. You can even upload them onto the box and take them with you. The box stores 32 GB, so you can load it with content and take it with you on an airline flight. (The promo video actually shows a passenger putting on the headset and secluding herself from the other passengers in this way.)

And you’ve also got the internet. For that you don’t have to connect via your computer, as the device has very good WiFi. Apart from a couple of occasions when the sound went a bit wobbly, we found it to have a very good connection and to run smoothly. And this was for YouTube, which sometimes has its own bandwidth problems. Also, there are many internet sources of content, including the many TV channels that also offer internet services, especially news channels. Plus of course, that vast world of content on YouTube.

As we reported on August 16, Royole Corporation has signed a deal with Sony to supply movies for the Royole Moon via an app called Royole Lounge. But in fact, any movie that is available on a disk or as a download can be relayed to the headset or transferred to the 32GB box, via HDMI, USB or Wifi. More generally, the Royole Moon has its own operating system (Moon OS)

I tried it out with news, music, sport and even some relaxation videos with quiet music, rivers and waterfalls. It was truly relaxing and the only thing I didn’t like was having to come out of it and back into the real world!

Physical comfort

This is a highly subjective issue. The headset is nicely padded and contoured to fit the round shape of a human head. But it feels a bit heavy and at times there is a sense that it is “pulling downwards”. In order to ensure that it doesn’t admit any ambient light, it is important to make sure that it is fitted tightly. Both the headband that covers the top of the head and the viewing part of the unit can be expanded and contracted (like better quality headphones) to accommodate different size heads.

The padding around the eyes (together with appropriate fitting adjustments) ensures that ambient light is kept out and the experience is truly immersive. However, the bulk of the padding can also create a somewhat claustrophobic feeling. I wouldn’t call it a feeling of suffocation, but my breathing was heavy in the first few minutes of putting it on. This may have been due to the after-effects of a winter cold.

At any rate, once I got used to it, I felt fine. In fact, as I mentioned above, taking it off and coming back into the real-world was also a bit of a psychological adjustment after that wonderful feeling of immersion that I got while wearing it and watching videos.

Some people have complained of feeling sweaty. I didn’t notice that, although the lenses did eventually steam up a bit. But Royole have thought of that and provided a cleaning cloth for those occasions. I only had to use the lens cloth a couple of times and it did the job fine.

Battery Life and Charging

The device charges in a couple of hours and can run for about five hours on a single charge. This is practical in most situations. Even if you were using it on a long-haul flight, you probably wouldn’t be using it continuously. And on long-haul flights, you might even be able to plug it in to recharge it.

Physical durability

This is not a heavy-duty appliance – and probably not designed to take the kind of knocks and bruises that a gaming headset might be subjected to. However, as the unit that we received for test purposes was on loan, we couldn’t really test its durability. It felt like it could get through normal, everyday usage unscathed.

But a device like this is not always subject to “normal” usage. It is intended to be used not only at home but also “on the road” and for airline trips. In those conditions, it’s bound to take a few knocks. And because it is not really a rugged item, that could be a problem. Royole thoughtfully provides a soft bag for carrying the headset and control box. But I would have preferred a harder case for transit and travel.

But even a hard case couldn’t protect it from the hard knocks that it might take within the home environment. Let’s face it, it will sometimes be used as a pacifier for children and teenagers. As such, one would expect it to get some rough treatment over its normal lifespan.

But it’s not clear if it even could be ruggedized. To so, it would inevitably lose one of its most compelling features…

Aesthetics and design

The Royole Moon is one of the most beautifully designed products I have ever seen. When we first unboxed it, we noted that it had the kind of design features we might have expected form a product by Apple. I also noted that it looks like the kind of thing that could have been a prop in Stanley Kubrick’s 2001: A Space Odyssey.

There is little more we can – or need to – say on this subject, as the pictures speak for themselves.

Value for money

This is a rather difficult question, because there is no getting away from one painful fact: the Royole Moon is expensive.

At $799.00 in the USA and £718.60 in the UK, it is a high price to pay for what is admittedly a wonderful viewing experience. Unlike an expensive, widescreen, high definition television that can be viewed by the whole family at the same time, this headset can only be viewed by one person at a time. Even the benefits of 3D are to a large extent outweighed by the fact that once again (as in the fifties and thirties) 3D hasn’t really caught on. This may be due to the dizzying effects of active viewing glasses or the fact that we only really perceive 3D up to a distance of about 50 feet anyway. Sweeping panoramic views and long shots are not really enhanced by stereoscopic vision. High resolution, contrast and a high refresh rate are far more important.

But that is perhaps a point in the Royole Moon’s favour. It has all these qualities and 3D. Indeed, maybe as more products like this arrive on the market, there will be yet another resurgence of 3D and maybe this time it will catch on. But at this stage, that is pure speculation.

So, I suppose the question should be: would you buy the Royole Moon if you had the money? I don’t mean scraping the money together and forgoing other pleasures. I mean if you were a man or woman of means, and could afford the best, would this be on your shopping list? As I am not a man of means, perhaps I am not the best man to answer this question. I appreciate the beauty of a Rolls Royce, but would I instead buy a  Lamborghini? Or a Tesla? In fact a Tesla is probably the closest analogy, because – like Tesla cars – the Royole Moon is on the cutting edge of technology and its appeal is based on advanced functionality, not snob-appeal. For this reason, my gut feeling is that if you’re the kind of person who can afford the latest “boy’s toys”, this would be on your list of must have items.

I know that I’d buy it!
