The Kiiroo Onyx+ is a premium automatic male masturbator that uses contracting rings to simulate realistic sensations. It’s the third generation in the Onyx series, with several improvements over its predecessors.
What makes it stand out is its interactive capabilities—it can sync with videos, VR content, and even other Kiiroo toys for long-distance play. Think of it as the Tesla of male masturbators: high-tech, sleek, and designed to elevate your experience.

“The Onyx+ isn’t just another masturbator—it’s an experience. The contracting rings create sensations that genuinely mimic the real thing, especially when paired with interactive content.”
Unboxing and First Impressions
When my Kiiroo Onyx+ arrived, I was immediately impressed by the discreet packaging. The outer box gave no indication of what was inside—a huge plus if you live with roommates or family members who might intercept your packages.
What’s in the Box?
- Kiiroo Onyx+ device
- RealFeel sleeve (already installed)
- USB charging cable
- Quick setup guide
- Authenticity and warranty card
- Sample packet of water-based lubricant
My first thought upon holding the Onyx+ was, “This feels premium.” The device has a substantial weight (about 2 pounds) and a sleek, matte black finish that looks sophisticated rather than tacky—something I appreciate in adult toys.
The build quality is excellent, with no loose parts or cheap-feeling components. The touch-sensitive buttons are responsive, and the overall design is ergonomic, though I did find it slightly bulky for one-handed operation (more on that later).
Pro Tip: Charge your Onyx+ immediately upon unboxing. The 4-hour charging time is no joke, and there’s nothing worse than being ready to test your new toy only to realize it needs several hours to charge first. Trust me on this one!
How the Kiiroo Onyx+ Works
The magic of the Onyx+ comes from its 10 contracting rings that work in harmony to create realistic sensations. Unlike traditional strokers that just vibrate, these rings contract and release in various patterns to simulate the feeling of oral or penetrative sex.
The device offers three main operating modes:
1. Manual Mode
In this mode, you control the contractions using the touch-sensitive panel on the device. Slide your finger up and down to adjust the intensity and pattern. I found this mode a bit awkward to use solo—it’s like trying to pat your head and rub your stomach at the same time, except… well, you get the idea.
2. Automatic Mode
This is where the Onyx+ starts to shine. It offers four preset patterns:
- Full Stroke: Consistent up and down motion (my personal favorite)
- Power Up: Gradually increasing intensity (great for edging)
- Handjob: Variable speed strokes
- Storm: Intense, random patterns (not for beginners!)
3. Interactive Mode
This is the Onyx+’s standout feature. Using Bluetooth and the FeelConnect app, you can:
- Sync with interactive adult videos
- Connect with VR content for immersive experiences
- Pair with another Kiiroo device (like the Pearl 2) for long-distance play
- Use the FeelMe AI to convert regular videos into interactive experiences
Important: The Kiiroo Onyx+ is NOT waterproof! While you can wash the removable sleeve, never submerge the main unit in water. A damp cloth is all you need to clean the exterior.
My Personal Experience with the Kiiroo Onyx+
After the seemingly endless 4-hour initial charge (during which I contemplated the meaning of life and reorganized my sock drawer), I was finally ready to put the Onyx+ through its paces.
Setup and Preparation
Setting up the device was straightforward. I downloaded the FeelConnect app, paired it via Bluetooth, and applied a generous amount of the included water-based lube to both myself and the sleeve. The app interface is intuitive, though I did experience occasional connectivity issues that required repairing.
Solo Play Experience
I started with the automatic modes to get a feel for the device. The Full Stroke mode provides a consistent, pleasurable sensation that mimics oral sex surprisingly well. The contracting rings create a unique feeling that’s distinctly different from manual strokers.
The Storm mode, however, was like going from 0 to 100 in a Ferrari—intense, unpredictable, and over before I knew what hit me. Consider yourself warned!
“The first time I tried the Storm mode, I lasted approximately 47 seconds. It was like my penis suddenly discovered it had places to be and important meetings to attend.”
Interactive Content Experience
This is where the Onyx+ truly shines. I tested it with some interactive videos from the FeelMe platform, and the synchronization was impressive. The contractions matched the on-screen action with minimal lag, creating an immersive experience that traditional masturbators simply can’t match.
I also tried the FeelMe AI feature, which converts regular videos into interactive experiences. The results were hit-or-miss—sometimes it synced perfectly, other times it felt completely disconnected from what was happening on screen.
Long-Distance Play
I convinced my long-distance partner to try the Kiiroo Pearl 2 so we could test the connectivity. When it worked, it was genuinely impressive—her movements with the Pearl 2 directly controlled the contractions of my Onyx+, creating an intimate connection despite being hundreds of miles apart.
However, we did experience occasional disconnections that required restarting the app, which somewhat dampened the mood.

Detailed Pros and Cons of the Kiiroo Onyx+
The Good Stuff
- Premium Build Quality: The Onyx+ feels substantial and well-made, with quality materials throughout.
- Realistic Sensations: The contracting rings create feelings that genuinely mimic real intercourse or oral sex.
- Interactive Capabilities: The ability to sync with videos, VR content, and other Kiiroo devices is a game-changer.
- Multiple Stimulation Modes: The variety of patterns keeps things interesting and caters to different preferences.
- Discreet Design: It looks more like a premium speaker than a sex toy, which is great for discretion.
- Long-Distance Relationship Tool: The connectivity with partner devices makes it valuable for couples separated by distance.
The Not-So-Good Stuff
- Lengthy Charging Time: Four hours of charging for one hour of play feels excessive in 2024.
- Noisy Operation: The motor produces a high-pitched whirring sound that’s definitely noticeable.
- Premium Price Tag: At around $219, it’s a significant investment compared to non-interactive options.
- Paywalled Content: Many of the best interactive videos require additional subscriptions.
- Delicate Sleeve: The TPE sleeve tears easily if you’re not careful during cleaning or storage.
- Occasional Connectivity Issues: The Bluetooth connection can be finicky at times.
- Bulky for One-Handed Use: The size and weight make it challenging to operate with just one hand.
Noise Level Reality Check: While Kiiroo claims the Onyx+ is “quiet,” I found it produces a distinct mechanical whirring sound during operation. It’s not room-shakingly loud, but it’s definitely audible from behind a closed door. If you have thin walls or nosy roommates, you might want to time your sessions strategically or add some background music.
How Does the Kiiroo Onyx+ Compare to Alternatives?
Before dropping $219 on the Onyx+, it’s worth considering how it stacks up against other popular male masturbators on the market.
| Feature | Kiiroo Onyx+ | Kiiroo Keon | Lovense Max 2 | Autoblow AI |
| Price | $219 | $249 | $199 | $299 |
| Max Strokes/Min | 140 | 230 | N/A (vibration) | N/A (blowjob motion) |
| Battery Life | 1 hour | 1 hour | 3.5 hours | Corded |
| Interactive | Yes | Yes | Yes | Yes |
| VR Compatible | Yes | Yes | No | Yes |
| Size/Portability | Medium | Large | Medium | Large |
| Noise Level | Moderate | Loud | Quiet | Loud |
Kiiroo Onyx+ vs. Kiiroo Keon
The Keon is Kiiroo’s newer, more powerful automatic stroker. It offers faster strokes (230/min vs. 140/min) and works with Fleshlight sleeves, but it’s significantly larger and louder than the Onyx+.
Choose Onyx+ if: You value portability and quieter operation.
Choose Keon if: You want more power and don’t mind the larger size and noise.
Kiiroo Onyx+ vs. Lovense Max 2
The Lovense Max 2 uses a combination of vibration and air pump technology rather than contracting rings. It has a longer battery life and is generally quieter, but doesn’t offer the same realistic stroking sensation.
Choose Onyx+ if: You prefer stroking sensations over vibration.
Choose Max 2 if: Battery life and quieter operation are priorities.
Kiiroo Onyx+ vs. Autoblow AI
The Autoblow AI uses AI-powered algorithms to simulate oral sex. It’s corded (no battery concerns) but much larger and louder than the Onyx+. It focuses specifically on blowjob sensations rather than general stroking.
Choose Onyx+ if: You want portability and versatility.
Choose Autoblow AI if: You specifically want oral simulation and don’t mind the size and cord.
Cleaning and Maintenance
Proper cleaning is essential for both hygiene and longevity of your Onyx+. Fortunately, the process is relatively straightforward:
How to Clean the Onyx+
- Remove the grip clip from the bottom of the device
- Take out the sleeve from the main unit
- Rinse the sleeve thoroughly with warm water and mild soap
- Flip the sleeve inside out to clean all surfaces
- Rinse again to remove all soap residue
- Pat dry with a lint-free towel
- Allow to air dry completely before reassembly
- Wipe the main unit with a slightly damp cloth (never submerge in water!)
Pro Tip: After cleaning, lightly dust the sleeve with cornstarch (not talcum powder) to prevent it from becoming sticky and to extend its lifespan.
Sleeve Maintenance
The TPE sleeve is the most delicate part of the Onyx+. To extend its life:
- Only use water-based lubricants (silicone-based will degrade the material)
- Handle gently during cleaning to prevent tears
- Store in a cool, dry place away from direct sunlight
- Consider purchasing replacement sleeves if you use the device frequently
Replacement sleeves cost around $25-30 and are available in standard and tight versions. Based on my experience, with proper care, a sleeve should last 3-6 months with regular use.
Frequently Asked Questions
How loud is the Kiiroo Onyx+?
Despite marketing claims of being “quiet,” the Onyx+ produces a noticeable high-pitched whirring sound during operation. It’s not extremely loud, but it’s definitely audible from behind a closed door. If discretion is a top priority, you might want to add some background music or wait until you have privacy.
Is the Kiiroo Onyx+ waterproof?
No, the Onyx+ is not waterproof. While the sleeve can be removed and washed with water, the main unit should never be submerged. Use only a slightly damp cloth to clean the exterior of the device.
How long does the battery last?
The Onyx+ provides approximately 1 hour of use on a full charge. It takes about 4 hours to fully charge from empty, which is one of the device’s drawbacks.
Can I use the Onyx+ with any video content?
Yes and no. The Onyx+ works best with specially encoded interactive content from platforms like FeelMe. However, the FeelMe AI feature attempts to convert regular videos into interactive experiences with varying degrees of success. Premium interactive content often requires additional subscriptions.
What lubricant should I use with the Onyx+?
Only use water-based lubricants with the Onyx+. Silicone-based or oil-based lubricants will degrade the TPE sleeve material. Apply lubricant both to yourself and the inside of the sleeve for the best experience.
How does the Onyx+ compare to the previous models?
The Onyx+ improves on previous models with better motor performance, more manual modes, and an updated design that’s easier to hold. It maintains the same core technology of contracting rings but with improved reliability and sensation.
Final Verdict
After several weeks of testing the Kiiroo Onyx+ in various scenarios, I’ve developed a love-hate relationship with this device. The technology and concept are impressive, but there are some practical limitations to consider.
Who Should Buy the Kiiroo Onyx+
- Tech enthusiasts who appreciate innovative adult toys
- People in long-distance relationships looking to maintain intimacy
- VR porn enthusiasts seeking more immersive experiences
- Those willing to invest in a premium masturbation experience
Who Should Look Elsewhere
- Budget-conscious shoppers (there are cheaper options available)
- Those prioritizing discretion (due to the noise level)
- People who prefer simplicity over tech features
- Those without reliable privacy for charging and maintenance
The Kiiroo Onyx+ represents the cutting edge of male pleasure technology, but it comes with a premium price tag and some practical limitations. When everything works as intended, it delivers an experience that traditional masturbators simply can’t match—especially for long-distance couples or VR enthusiasts.
However, the lengthy charging time, noise level, and occasional connectivity issues prevent it from being a perfect product. If you’re willing to work around these limitations and invest in the ecosystem (including potentially paying for premium interactive content), the Onyx+ can significantly elevate your solo sessions.
