Kiiroo Onyx+ Review: Brand Overview and First Impressions
You probably know that onyx is a sleek black semi-precious stone known for its polished and elegant appearance. The same idea carries over to the Kiiroo Onyx+ automatic masturbator. I’ll get straight to the point: it’s one of the most stylish and premium-looking male sex toys I’ve tested. It also has a strong reputation as one of the top-selling automatic strokers on the market, so I was genuinely curious to see whether it lived up to the hype during my hands-on testing.
And if you’re not familiar with Kiiroo, this Dutch sex toy company has become one of the leading names in interactive, app-enabled sex tech and long-distance connectivity. Scarlett and I have tested several of their products before, and they consistently stand out for their innovative features and immersive experiences. So what exactly is the Onyx+, and how does it work for solo sessions or interactive partner play? Let’s take a closer look.
First Impressions of the Kiiroo Onyx+
When I started my Kiiroo Onyx+ review, I already knew this device was packed with features and offered several different ways to use it. Like most Kiiroo products, the Onyx+ works perfectly well as a standalone automatic stroker for solo sessions. However, it also supports the FeelConnect app, which opens the door to remote control features, interactive content, and a much more connected experience. On top of that, if your partner owns another compatible Kiiroo toy, the two devices can sync together for interactive long-distance play.
So based on my first impressions, I already had a feeling this toy was going to offer a lot of value for the price. It was also clear right away that the Onyx+ is versatile enough to support a wide range of experiences, whether you’re using it solo, with interactive content, or as part of long-distance partner play.

Onyx+ vs Onyx 2: What’s New
It’s worth mentioning that the Onyx+ is an upgraded version of the earlier Onyx 2 model, with several noticeable improvements. That includes better grip performance and a redesigned internal system featuring 10 contracting rings that create a more dynamic and realistic sensation without feeling overly restrictive.
Another major improvement over the Onyx 2 is the updated soft-touch glossy finish. The device itself has a sleek, discreet appearance that resembles a modern tech gadget more than a traditional adult toy. It’s also capable of reaching speeds of up to 140 RPM, giving you a wide range of intensity options to experiment with.
You can switch between slower, more controlled rhythms and much faster settings depending on your preferences. The continuous up-and-down contractions feel surprisingly immersive, and the variety of modes helps create different types of sensations throughout the session. There’s definitely a lot to explore with the Onyx+, especially if you enjoy customizable and interactive experiences.
Top Features of the Kiiroo Onyx+
- 10 internal contracting rings – deliver realistic up-down stroking sensation
- Removable RealFeel TPE sleeve – body-safe, soft, ribbed internal texture
- Bluetooth FeelConnect app remote control
- Interactive sync: VR content, 3D sex games, 2D video and live cam shows
- Extremely quiet operation
- Long-distance play – connects to compatible Kiiroo female sex toys
- 5 manual modes: Manual, Full Stroke, Power Up, Handjob, Storm
- Insertable length: 6.5 inches (recommended girth: 1.5–1.7 inches)
- 140 RPM max speed
- Battery: 1-hour use / 4–6 hour charge
- Not waterproof – unit must be kept dry; sleeve washed separately
💡 Pro Tip: Before your first session with the Onyx+, check your girth against the manufacturer's recommended range of 1.5 to 1.7 inches. If you're above average girth, the 10-ring mechanism may feel uncomfortably tight. If you're on the smaller side, start with the Manual mode rather than the faster Storm or Power Up modes - the control is more precise and you'll get more from the texture.
Sleeve, Controls and Modes
The Sleeve
One of my favorite things about this toy is the removable sleeve. It’s a RealFeel sleeve that is made of TPE. This material is body safe and super realistic, but the sleeve design on the Onyx+ is actually quite different from any other products. The sleeve is white with ribbed textures on the inside and it sort of resembles a big condom when you remove it from the case. To me, it feels a lot softer compared to other sleeves and I genuinely enjoyed all the bumps along the shaft.
How Does it Work?
Another awesome feature I genuinely enjoyed during this Kiiroo Onyx+ review is the nearly silent operation of this male masturbator. Somehow, they’ve managed to keep the motor powerful enough but lower the noise. This is actually not that common for automatic masturbators since most of them make a lot of noise, but using the Onyx+ was as quiet as it gets. This may be due to the newly designed motor that wasn’t available in the older Onyx 2. Either way, you’ll get 10 rings that work together to create an incredibly realistic sensation of vaginal, oral or anal sex depending on the setting you choose.
Manual Mode
There are a total of five different manual modes and you can access them via the convenient LED buttons on the side of the stroker. These modes don’t require you to connect to Bluetooth, so they’re a good solution if you’re in a rush. You can choose from Manual, Full Stroke, Power Up, Handjob and Storm modes. Plus, there’s a small touchpad on the side that enables you to adjust the intensity and it’s a really handy option to have if you want to adjust the settings on the fly.
Bluetooth Mode
Of course, to unlock the full capabilities of the Onyx+, you’ll need to pair it with Kiiroo’s FeelConnect app via Bluetooth. The setup process only took a few minutes, and once connected, I was able to explore the toy’s interactive features right away. For example, I synced the Onyx+ with Scarlett’s Pearl2 vibrator, allowing us to control each other’s devices through the app with simple gestures and adjustments.
Even though we tested it together at home rather than in a long-distance setting, the experience still showcased how interactive and engaging the system can be. The synchronization between the devices added a fun and immersive element that made the whole setup feel much more connected and dynamic.
However, if you’re not looking for a long-distance toy, I can tell you that the Onyx+ truly shines during interactive videos, VR content and even cam shows. You can connect the Onyx+ to Kiiroo’s FeelPornstars site, which has a massive library of immersive interactive videos. When you connect the Onyx+ to a hot video of your choice, the internal rings will start to mirror the movements in the videos.
What I really liked here was how the constriction rings worked together with the motor to create a much more immersive interactive experience. The rings adjust dynamically to match the synced motion, whether the pace is slower and more relaxed or much faster and more intense. On top of that, the FeelPornstars platform includes a large library of interactive content featuring well-known performers, which adds another layer of realism and personalization to the experience.
Testing the Onyx+ In Action
As I mentioned earlier, Scarlett and I have tested several Kiiroo products before, and they’ve consistently delivered strong interactive experiences. My favorite thing about the Onyx+ is the sheer variety of ways you can use it. Whether you prefer solo sessions, app-controlled partner play, or long-distance interaction, the device offers plenty of flexibility and features to experiment with.
That said, there were a couple of drawbacks worth mentioning. The charging time is fairly long at around 4 to 6 hours, while battery life tops out at roughly one hour per session. For most users that will probably be enough, especially considering how intense and immersive the device can feel, but it’s still something to keep in mind.
I also noticed that the sleeve felt a bit short for my preferences. The maximum insertable length is around 6.5 inches, so users above that range may not get full-depth use from the device. Kiiroo also recommends an optimal girth range of roughly 1.5 to 1.7 inches, so it’s definitely worth checking the sizing recommendations beforehand to make sure the fit will be comfortable.
What I Liked
- 10 contracting rings deliver convincing up-down stroking motions – the standout feature
- Flawless interactive play – VR sync, live cam shows, long-distance partner control all work reliably
- Exceptionally quiet – significantly quieter than most automatic masturbators
- 5 manual modes accessible without app – good for quick standalone sessions
What I Didn’t Enjoy
- Long charge cycle: 4–6 hours for 1 hour of use
- Not waterproof – unit cannot be submerged; sleeve washed separately
- Sleeve removal for cleaning is fiddly – inner ring must be opened carefully
- 6.5-inch insertable length may not suit larger users
- Girth restriction: manufacturer recommends 1.5–1.7 inch girth – worth checking before purchase

Summary
Honestly, the Onyx+ delivered a very intense and immersive experience right from the start. It took me a few sessions to fully adjust to the realistic sensations and automated contractions, which actually made the experience feel more engaging over time. Once I got used to it, I found it easier to pace myself and enjoy longer sessions overall.
On top of that, the Onyx+ is an extremely versatile device with a strong mix of interactive features, app connectivity, and customizable settings. Whether you’re interested in solo play, synced content, or partner interaction, it offers a lot of functionality for the price and stands out as one of the more advanced automatic strokers currently available.
Who Should Buy the Kiiroo Onyx+?
Buy it if:
- You want a 10-ring automatic masturbator with VR, interactive video and live cam sync
- You want long-distance play – compatible with Kiiroo female toys via the FeelConnect app
- You want exceptionally quiet operation – the redesigned motor is the quietest in this category
- Your girth is 1.5 to 1.7 inches – the Onyx+ is optimized for this range
- You want 5 manual modes for standalone use without app setup
Skip it if:
- Your length is above 6.5 inches – the sleeve may not accommodate full depth
- Your girth exceeds 1.7 inches – the contracting rings may feel too tight
- The 4-6 hour charge for 1 hour of use is a concern – consider the Keon for longer sessions
- You need waterproof use – the Onyx+ cannot be submerged
Mistakes to Avoid With the Kiiroo Onyx+
- Expecting a full stroking machine. The Onyx+ does not work like the Kiiroo Keon or The Handy. Instead of moving the whole sleeve up and down, it uses 10 internal contracting rings to create a realistic up-down sensation. If you want physical thrusting motion, choose a stroking machine instead.
- Ignoring the girth range. The Onyx+ is optimized for a 1.5 to 1.7-inch girth range. If you are above that, the contracting rings may feel too tight or uncomfortable. If you are below that range, start with Manual mode so you can control the intensity more precisely.
- Buying it for full-depth use. The insertable length is around 6.5 inches, so larger users may not get complete depth. Buy it for the contracting-ring sensation, app sync, quiet motor and interactive features, not for maximum sleeve depth.
- Starting with Storm or Power Up right away. The 5 manual modes feel very different, and the faster settings can get intense quickly. Start with Manual or Full Stroke first, then move into Power Up, Handjob or Storm once you understand how the rings respond.
- Skipping the FeelConnect setup before use. If you want VR sync, 2D interactive content, cam show support or long-distance partner control, pair the Onyx+ with the FeelConnect app before applying lube. Troubleshooting Bluetooth after setup gets messy fast.
- Forgetting about the long charge time. The Onyx+ takes around 4 to 6 hours to charge and gives roughly 1 hour of use. Charge it before longer sessions, especially if you plan to use interactive content or partner control.
- Submerging the device. The Onyx+ is not waterproof. Remove the RealFeel TPE sleeve and wash it separately, but keep the electronic shell dry. Wipe the outer case with a damp cloth only.
- Rushing the sleeve removal. Cleaning is easier once the sleeve is out, but the inner ring needs to be opened carefully. Forcing the sleeve out can make cleaning more annoying and may damage the fit over time.
- Leaving the TPE sleeve damp. After washing, let the sleeve dry fully before placing it back inside the shell. Trapped moisture inside a TPE sleeve can lead to odor, material breakdown and hygiene issues.
- Using silicone or oil-based lube. The Onyx+ sleeve is made from RealFeel TPE, so water-based lube is the safest choice. Silicone and oil-based lubes can degrade the sleeve over time.

The Kiiroo Onyx+ Lowdown – What You Need to Know
Intermediate to advanced users who want a versatile automatic masturbator for solo use, partner control and interactive content. The 10-ring contraction system and quiet motor are standout features. Built from ABS and TPE – solid construction. Limitations: 4-6 hour charge for 1 hour use, 6.5-inch insertable (not ideal for above-average length), and 1.5-1.7 inch girth recommendation.
Ships in a plain cardboard box – no adult product labelling visible externally. 1-year warranty covering manufacturing defects in materials and workmanship. Warranty does not cover wear, misuse or tampering. Proof of purchase required. Replacements issued, not refunds.
Yes. ABS outer shell and RealFeel TPE sleeve – both body-safe. Water-based lube only. Silicone or oil-based lubricants will degrade the TPE sleeve over time.
Remove the sleeve and wash with warm water and mild soap or toy cleaner after every session – the sleeve removal is fiddly; open the inner ring carefully. Wipe the outer shell with a damp cloth only – not waterproof, do not submerge. Dry fully before storing. Store in a cool, dry place away from heat and sunlight.
The Onyx+ offers improved grip performance, a redesigned quieter motor and a glossy soft-touch finish. The 10-ring contracting mechanism is retained from the Onyx 2 but is more responsive in the Onyx+. The FeelConnect app integration is the same, though the Onyx+ benefits from updated firmware compatibility. The external case is functionally similar – a discreet design that resembles a Bluetooth speaker.
No. The Onyx+ and the Keon are separate automatic masturbator products from Kiiroo. The Onyx+ uses contracting rings; the Keon uses a stroking sleeve mechanism. They do not physically link. However, both connect to the FeelConnect app and either can be used for long-distance play by pairing with a compatible Kiiroo female toy.
Yes. The Onyx+ syncs to VR videos, 3D sex games, 2D interactive videos and live cam shows via the FeelConnect app. The internal rings mirror the movements in the content in real time. The FeelPornstars platform hosts a large library of compatible interactive videos. A VR headset is required for VR-specific content.
Kiiroo recommends a girth of 1.5 to 1.7 inches for the optimal experience. Users above 1.7 inches may find the contracting rings uncomfortable. The maximum insertable length is 6.5 inches. Check your measurements before purchase – these are real constraints, not general guidance.
