Kiiroo Onyx+ Review: The Most Powerful Automatic Masturbator Ever?!

Do you remember when you binged on Breaking Bad for the first time and couldn’t stop watching for hours? That’s exactly how I felt with the Kiiroo Onyx+ – I just kept coming back to it. The main selling point for me is the unique contracting-ring motor that simulates up-down motions of real sex and delivers a genuinely different experience from standard strokers. Check out my Kiiroo Onyx+ review to learn all about my experiences with this next-gen masturbator!

Quick Verdict

The Kiiroo Onyx+ is best for users who want a quiet, app-enabled automatic masturbator with 10 contracting rings, FeelConnect support, VR/2D/cam-show sync and long-distance partner control. Its biggest strengths are the realistic up-down ring contractions, 5 manual modes, interactive content compatibility and low noise level, while its main drawbacks are the 6.5-inch insertable length, narrow 1.5-1.7 inch recommended girth range, 4-6 hour charge time and non-waterproof body.

• Best for: Users who want interactive app-connected stimulation without the bulk or noise of a full stroking machine.
• Skip it if: You need deeper insertion, a wider fit, waterproof cleaning or long battery life.
• Main strength: The 10 contracting rings create a distinctive up-down sensation that feels different from regular vibration or static sleeves.
• Main drawback: The fit range and 6.5-inch insertable length may feel limiting for larger users.
• Final verdict: A premium interactive masturbator for users who value quiet performance, app sync and realistic ring contractions over depth, girth flexibility and easy cleaning.

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

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.

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+?

Mistakes to Avoid With the Kiiroo Onyx+

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
