Kiiroo Onyx+ Interactive Masturbator

L’Onyx+ is Kiiroo’s interactive male masturbator built around contracting rings rather than simple vibration. The brand presents it as a deliberately gentle-touch device, aimed at those who find most masturbators too intense. It fits into Kiiroo’s connected ecosystem, with an app, synced content, and remote play. This fact sheet summarizes and rephrases information published by the manufacturer: we have not tried the device and make no judgment on how it feels.

Contracting rings rather than simple vibration

The principle highlighted by Kiiroo relies on ten rings that contract in sequence inside the device. The brand states that this mechanism creates a continuous stroking motion along the penis, similar to a back-and-forth movement, where many masturbators rely solely on a vibrating motor or a suction system. Kiiroo emphasizes the deliberately measured nature of this stimulation: the Onyx+ is described as a gentle-handed device, designed to stay comfortable over time. The manufacturer explicitly cites three user profiles: people dealing with premature ejaculation, those with a smaller-than-average size, and those who find masturbators on the market too intense. Kiiroo does not publish numerical data on the force exerted by the rings, nor a measured sound level.

Touch interface, modes, and custom patterns

Kiiroo equips the Onyx+ with a touch surface built into the device’s body, presented as a way to adjust settings without fumbling for a button. The brand announces six preset modes, plus customizable patterns: users can therefore stick with a rhythm offered by the device or build one that suits them better. This logic ties into the central argument of the manufacturer’s product page, summed up by the phrase “you stay in control”: the rhythm follows the user rather than the other way around. Kiiroo also highlights an endurance-training use, with the device able to help build stamina rather than chase the strongest possible stimulation. The exact details of the six modes, their respective intensities, and how precisely to create a pattern are not described on the product page.

FeelConnect, synced content, and remote play

The Onyx+ is part of Kiiroo’s connected ecosystem. The manufacturer provides the FeelConnect app, which serves as the entry point for the various features announced: syncing with interactive content, so the device reacts in real time to what’s being watched; virtual reality experiences; and remote couple play, with each partner controlling or feeling the other wherever they are. Kiiroo also adds one free month of access to FeelMe AI, its AI-assisted content service. The brand sums up this versatility as follows: one device, several ways to use it, solo or as a couple. The product page does not specify the list of compatible platforms, the operating systems required for the app, or the connection protocol used.

Interchangeable sleeves, battery life, and box contents

Kiiroo ships the Onyx+ with a sleeve described as “regular fit,” meaning a standard snugness. The brand mentions a second, tighter sleeve, sold separately for users looking for more contact — a point consistent with the device’s overall positioning. Replacement sleeves are sold in packs of three, allowing the skin-contact part to be renewed without replacing the device itself. On the power side, the manufacturer claims about two hours of battery life and includes a USB charging cable. The box contains the device, the standard sleeve, the cable, and the user manual. Kiiroo mentions a one-year warranty and discreet packaging. However, the page does not state the charging time, the device’s dimensions, the exact sleeve material, or a cleaning protocol: the included manual remains the reference on this point.

Who Kiiroo designed this device for

The product page displays an unusually explicit positioning: Kiiroo isn’t trying to sell the Onyx+ as the most powerful masturbator in its lineup, but as the gentlest. The sensitivity argument comes up repeatedly, whether referring to naturally high sensitivity, discomfort with very tight devices, or a desire for better timing control. The endurance-training option, featured within the Kiiroo ecosystem, extends this logic: the device can be used to learn to recognize and modulate arousal, not just to reach orgasm. For those wanting a firm, tight stimulation, the brand instead points toward other models in its catalog. These are the manufacturer’s claims; they describe a design intent, not a result we were able to verify ourselves.

Frequently asked questions

Is the Onyx+ suitable if regular masturbators feel too intense?

This is precisely Kiiroo’s central argument. The manufacturer describes the Onyx+ as a gentle-touch device, with its ten contracting rings producing a gradual caress rather than strong pressure. It explicitly cites highly sensitive users and those who find other models too aggressive. We cannot confirm this sensation ourselves: only the brand makes claims on this point.

Can you get a tighter fit?

Yes, according to Kiiroo. The device ships with a standard-fit sleeve, and the brand offers a second sleeve providing a tighter fit, sold separately. Replacement sleeves are also available in packs of three. Kiiroo does not publish the internal diameters of these different versions on the product page.

What’s the battery life and how long does charging take?

Kiiroo claims about two hours of battery life and includes a USB charging cable in the box. However, the manufacturer does not specify how long a full charge takes, nor the battery capacity. This information may be included in the user manual shipped with the device.

Does it work remotely with a partner?

Kiiroo presents remote play as one of the uses within its ecosystem: via the FeelConnect app, the device can be paired with a partner at a distance, as well as synced with interactive content or used in virtual reality. One month of FeelMe AI is included. The exact list of compatible platforms is not detailed on the product page.

Who it’s for

Based on Kiiroo’s stated positioning, the Onyx+ is aimed at users looking for controlled rather than maximal stimulation: high sensitivity, discomfort with very tight sleeves, or a desire to work on endurance. It also targets those interested in the connected aspect, for syncing the device with content or with a remote partner. Anyone mainly seeking raw power will find other options in the brand’s catalog.
