Onyx+ is an interactive male masturbator that offers a gentle, more controlled experience, making it a great fit for people who experience premature ejaculation, have a smaller penis, or find most male masturbators too intense. With customizable settings, a snug fit, and a smooth stroke system, Onyx+ puts you back in control of your pleasure.
Inside, ten contracting rings work together to create a smooth, stroking sensation that you can adjust to suit your pace. Choose from six built-in modes or create your own custom pattern. The motion is consistent and easy to manage, ideal if you’re more sensitive or want to take things slow. Onyx+ is also lightweight, discreet, and made from body-safe materials that feel just as good as they look.
Size matters when it comes to fit.
Onyx+ is best suited for penises with a diameter between 3.5 to 4.3 cm (1.38 to 1.69 inches) and up to 16 cm in length (6.3 inches). The tight-fit sleeve (does not come in the box but can be bought separately) supports smaller sizes—3 to 3.5 cm (1.18 to 1.38 inches)—offering a more snug fit that’s ideal for smaller penises.
Use Onyx+ solo, or sync it with interactive content via FeelMeAI to match every movement on screen. You can also connect with a partner through the FeelConnect app and sync your toys in real time, no matter the distance.

"The tool itself is very interesting and very inventive, but somehow the potential it has has not been exploited, or the development has hit a dead end. It is usable and somewhat satisfying, but I expected more and was a little disappointed."
"Might work for others. I have the whole set and have to say, sadly, the Onyx is the weakest of them. While in theory it sounded amazing, it just don't really work for me. It is a high quality product but it just does not feel as lifelike as the others."
"I am always sceptical about these types of devices, especially after my last purchase of the Powerblow, which was so disappointing. This time it's a different story. After reading reviews, I was inclined to cancel the purchase. I decided to give it one last try, and I have to be honest. . . I'm surprised. The motor noise is really not bad, just a modest brr brr sound. Only the stroke could be a little more powerful; it feels yes and no. Overall, it meets my expectations in combination with FeelMeAI. I've had the device for 1. 5 months now and am enjoying it more every day. Will there perhaps be an update to give the stroke more power? Hoping for a feelpornstar sleeve release."
"Like the feeling it give but have some trouble with connectivity loss"
"Feels great."
"I got this for free when buying other items from Kiiroo - personally, I don't think it's a good as the keon. The onyx sleeve just isnt as nice as a feel stroker. In a vacuum the onyx is fine, but I'd rather use the keon. It does have it beat on ease of clean up though."
"Super 👍"
"got it for free, great free content"
"A very good choice if you’re well hung, and you like a more subtle “milking” sensation. The sleeve is fairly thin, and doesn’t offer much “compression”, and the unit that creates the massaging is wide enough that us mere mortals really can”t get an intense sensation. That said, it is very good at edging, and the FeelMe integration is top notch. Overall, it’s pretty good, and if you get it on sale, ($50 on the Easter sale)- it’s one of the better deals out there."
Whether you play solo, sync with interactive platforms, explore VR or AI, or connect with a partner, your Kiiroo toy adapts to whatever you want to feel.
One system with endless ways to experience real time sensation.
