Kiiroo Onyx 2 Review:

Is The Onyx 2 Really Worth Buying?

Written by: Don Watson | Updated: September 16th, 2019

Are you looking for a male masturbator that will do 99% of the work for you?

The Kiiroo Onyx 2 is a unique male masturbator which takes all of the manual stimulation out of using a male masturbator.

The Onyx 2 has built-in motors which massage your penis in a very satisfying way. Just insert your penis, press the button and let the Onyx 2 take care of the rest.

Gone are the days of stroking your penis manually, the Onyx 2 can do it a lot better than you can.

The Kiiroo Onyx 2 is a single unit that contains both the Fleshlight sleeve as well as all of the mechanical goodies required for stimulating the penis.

It's a fully automatic masturbator, as in all you need to do is insert and press play and the rest is handled by the toy itself.

No effort is required on your part besides that required to keep your manhood fully inserted and trust me, you'll be in for a wild ride.

Kiiroo is an interesting company as far as business relationships go, they're one of the few non-Fleshlight brands that utilize Fleshlight's proprietary Superskin material.

They make what they describe as luxury brand sex toys, but I'd primarily consider them to be a tech company as opposed to a sex toy company. They brought the tech-savvy, Fleshlight brought the sex savvy.

The Launch is a great example of this partnership, it was a device you could thread your Fleshlight into and it would move it up and down however you'd enjoy most.

Kiiroo has decided to go down a different road when it comes to the Onyx 2, however.

The Kiiroo Onyx is a totally unique male masturbator. Not in its design, as it resembles many other products I've used like Fleshlights, but in the experience it provides.

After using the Onyx 2 my penis is absolutely addicted to how the inside of it feels when the toy is turned on. When I'm balls deep inside this toy, it's very difficult for me to last more than a minute without cumming, regardless of the setting I'm using. 

Let's get into the review...

What Is The Onyx 2?

As the name implies, the Kiiroo Onyx 2 is the second iteration of the Onyx male masturbator. It's been called everything from a blowjob machine to automated sex to anything in between, that's mostly marketing speak. In simplest terms possible, its a mechanical vibrator with a Fleshlight sleeve. I've never touched an original Onyx, but according to what I've read online they fixed issues with how the sleeve fits in the device, battery life, and few other touch-ups here and there.

Let's get some technical stuff out of the way. The exterior of the Onyx is constructed out of ABS and POM plastics, so the device is quite lightweight overall, no more than a kilogram at best. Its dimensions are 3.5''x 3.1'' x 10.3'', making it modestly large but still easy enough to get your hands around comfortably. The semi-rounded edges of the case make for a relaxed hand-feel. As far as insertable length is concerned we're working with 16.5cm or about 6.5'' of room inside the device, while it is accommodating as far as girth is concerned the particularly well-endowed lengthwise might want to seek out one of Kiiroo's larger toys.

The Onyx 2 is powered by a lithium battery with approximately 1 hour of total usage time (depends on which settings you choose) for every 4-6 hours of charge time. The ratio of charge to use isn't spectacular, but I found that the hour it does work is worth the wait.

How Does It Work?

What drew me to this toy was the idea of completely abandoning any need to move the toy myself and let modern technology take the reins of my masturbatory experience. The Onyx 2 is the only masturbation machine which claims to be a "penis milker" that doesn't look like you risk having your Johnson sheared right off with it.

The term "penis milking" is pretty silly in my opinion, but there's really only so many ways to get the idea across that the Onyx does all the work for you.

Here's a short visual demonstration that displays how the Kiiroo Onyx 2 works:

The motor inside functions to contract several joints throughout the device in an undulating stroking motion that provide up to 140 strokes per minute, or a little over two strokes per second. There are individual rings that the motor manipulates to compliment the soft, minimally textured sleeve. The sleeve inside is made from Superskin material, the exact same blend used in Fleshlight toys.

I don't know how they managed to team up with Fleshlight as Kiiroo seems to be a distinct company based out of Amsterdam, but I'd consider it to be a match made in heaven.

The added bells and whistles of the Onyx 2 is that it's compatible with VR and even without a VR headset can be synced up to porn videos as well as the motion of its female counterpart, the Pearl by Kiiroo. There are currently even a few pornographic games that are encoded to work with the Onyx 2, so I'd say it's a fairly big leap forward in the interactive sex department.

My Experience Using It

The main reason I bought the Kiiroo Onyx 2 was to see how well it'd stack up against long distance sex pioneer Lovense's toys, but that will be covered in another article, for this purposes of this experience it's an entirely solo trip.

After receiving the toy I promptly charged it to full battery and got to figuring out what this bad boy can do. I made sure the sleeve was securely inside the device, it is completely removable for cleaning time and is replaceable should it ever get too worn out, I'll probably have to take advantage of that soon enough. 

Once I had everything prepared, I inserted and laid back to see what awaited me. The ten distinct rings provided a fantastic sensation and I'm fairly certain they vibrate to some degree as well, or maybe that's just my genitals trembling at how great this thing works.

The ten ring design is different from the air-pump design of the Lovense Max and in my opinion, makes for a different experience altogether.

Let's just say I've never managed to use the Onyx 2 for the entire full hour battery life. I was also pleasantly surprised by not having to move the toy around whatsoever. It's a completely un-involved process from the user besides turning it on and choosing the right settings. I found it wasn't the greatest if I chose to thrust with the device, but it's absolutely phenomenal if you just lay back and let it do all of the work. Depending on your personal tastes, that may or may not be for you.

The most staggering thing about it was how quiet it was. I was expecting a sound, not unlike those Christmas toys that dance to a song and you can hear each and every gear whizzing along, boy was I in for a surprise. I wouldn't go as far to call it whisper quiet, but it's probably around 50-60% of the noise you'd expect from a traditional electric shaver as far as noise is concerned.

I absolutely love the design of the sleeve. They've made it relatively small and it comes out super easily to be cleaned after each usage as you'll be able to see from the next image.

What Comes With It?

Here's a short unboxing video of the Kiiroo Onyx 2 which outlines everything that comes in the box:

The Onyx 2 And Virtual Reality

Interactive mode with the Onyx 2 breaks a lot of new ground in the world of interactive sex toys. Many toys have for years tried to make the experience of masturbation feel less like you're a man in a dimly lit room passionately making love to himself and more like an actual sexual encounter with all of the blood-pumping intensity that comes with it.

As of writing, there's mainly three worthwhile ways to get down with the interconnected nature of the Onyx 2.

Firstly, there's interactive porn, and a lot of it. The volume of free content is growing weekly, I think I managed to get in on the fun when there was enough free content for it to be worth it, as I think it was severely lacking earlier on in the Onyx 2's release. I like my porn like I like my WinRAR, free of charge. Tons of toys before this one have tried to hype up how well they can be synced to pornography, but they all had the disadvantageous distinction of me having to move the toy around myself. 

So the automatic Kiiroo Onyx 2 was to be finally a way to lay back and zone into a proper video. It's fairly simple, connect the device to your phone and plop it in a VR headset, I went with a cheap $20 one I got at a local hardware store. From there, it was just a matter of finding the video I wanted and letting the code do all of the work. All in all, the videos are a pretty good time and much different than going about things manually.

The second option is hooking it up to a VR porn game. I don't have very much experience with the games themselves, but there appears to be two games that people actually play, one called Red Light Center and another called 3dX Chat. Red Light Center looks like a Second Life clone meant explicitly for getting nasty with other people, so I'd think if you can find someone to sync up to it would at least be mildly more stimulating than going at it alone. I'm not quite sure how it works or if it even works that well since I haven't used it myself, but the option is there.

Finally, many cam girls are starting to use toys that can be synced up to the Onyx 2. Simply enter a chat room and connect with the girl and transmit some sensations. Either control her toy manually while using yours or let her use a toy like the Pearl 2 to control which rings are being contracted and when. It's probably the most interactive out of all of the options for the Onyx, as it's another flesh and blood human being you're building sexual tension with.

If the standard Onyx 2 isn't quite your style and you'd rather spend a few extra bucks and get your favorite pornstar version, its available in 6 different custom versions. Each one comes pre-packed with a bunch of POV videos of the specific pornstar. 

Currently the models available are Lisa Ann, Tanya Tate, Jessica Drake, Asa Akira, Bobby Eden, Romi Rain. If any of those names happen to be a favorite of yours, for an extra $10 you can get a bunch of extra videos. All the videos are designed to be realistic and simulate more of a point-of-view style of porn. For and extra 10 bucks, you really can't go wrong.

Here's a video of the 6 different models of the Kiiroo Girls packages:

Parting Words

If you're in the market for a battery-assisted male masturbator that is quiet, effective, and superbly designed, the Kiiroo Onyx 2 is a great choice.

The teledildonic aspects of the Onyx 2 and the sheer amount of different ways to enjoy an hour of battery life. I am thoroughly impressed by how they engineered the motor to function and besides the occasionally bulky feel of the toy, it is pretty iron-clad as far as sex toys go.

For a toy that costs around $200 (using our coupon code), it's well worth it if you ask me. The Kiiroo Onyx 2 comes jam-packed with a ton of adult content included with tons of videos of top name pornstars. They actually just released a new paid addition which works in conjunction with which is a 3D virtual reality porn website which takes you right inside the scene as if you were actually there. The only caveat is that you have to pay for "coins" to have access to the content, although the POV films I checked out on there were pretty awesome if I'm being honest.

That being said, I'm more of a free porn kinda guy.

All things considered, the Kiiroo Onyx 2 has very quickly become one of my favorite male masturbators and one that I reach for quite regularly. It's a toy I'd highly recommend to anybody looking to take their masturbation game to the next level and experience a more hands-off experience.

Bit of a weird question for you but I’ve never owned a male masturbator before so bare with me.

How realistic does the Onyx feel? Like, I guess what I’m asking is, is it abundantly obvious when you’re using it that you’re being tugged off by a monotonous machine?

I’m looking to invest in a toy like this one but at like $200 I just want to make sure it’ll at least feel somewhat realistic so that I can get a good bang for my buck… no pun intended.

    Don Watson - February 25, 2019 Reply

    Well, I’ll tell you first off that while realistic isn’t entirely the right word for how it feels, monotonous isn’t the right word either. It’s very engaging, and it has a lot more realism going for it than other strokers. That’s mainly because the toy inside actually contracts and expands much like a real vagina does during sex. The textured sleeve isn’t where it gets the most realism points, but the motors that work with the pleasure rings makes it a very worthwhile experience.

    If you’re the type to watch some videos while trying to imagine yourself in the scene, the Onyx 2 is a good choice. Not having to move the toy around also helps you forget that you’re masturbating.

This toy is great, really. I’ve had the Onyx 2 for over 2 months now. It seemed expensive at first, but out of all of the uses I’ve gotten by this point it’s less than a dollar a wank, and for a hands-free time, I find it worth it.

In all seriousness though, it really is a pretty cool hands off masturbation experience. Does all the work for you.

The Onyx2 is the best hands-free masturbation experience I’ve ever had. Price is high but it works with Pornhub videos.

Taking a Tinder date out on a single date is about the same cost as on usage session with the device.

Can it be used on flaccid or semi erected?
How good it is for multiple orgasm.

    Don Watson - June 2, 2019 Reply

    Some rigidity is necessary otherwise you won’t get anywhere. A half chub should work just fine. When it comes to multiple orgasms Fauwad, that’s a different story. After you ejaculate there’s always a refractory period of some kind. You always could leave yourself inserted and hope for the best but I’d suggest letting your thing breathe.

    Prostate orgasms can occur in rapid succession, it might be worth looking into.
