Kiiroo Onyx+ App-Controlled Male Masturbator

The Kiiroo Onyx+ is an app-controlled male masturbator that moves for you: a sleeve inside the black cylinder is gripped by a ring mechanism that travels up and down the shaft, so you lie back while it does the work. It's lighter and quieter than earlier Onyx models, and it's built for connected play, from syncing with interactive videos to linking up with a partner's toy in another city.

How the motion feels

Onyx+ is the third-generation Onyx, with a rotating motor that drives a continuous up-and-down motion meant to mimic intercourse. It reaches up to 140 strokes per minute, which is slower at the top end than a Keon but more enclosed, with the movement wrapped around you rather than the whole sleeve sliding. Kiiroo says the motor runs more quietly than either of the earlier Onyx versions, and the compact size makes it easy to pack.

Ways to control the male masturbator

One button on the base turns it on and cycles through three modes. In manual mode you swipe up or down on the front trackpad to drive each stroke yourself. Automatic mode has four preset patterns: Full Stroke, Power Up, Handjob and Storm. Bluetooth mode connects to the FeelConnect app, which syncs Onyx+ with interactive videos, virtual reality and webcam sites, including content on FeelMe. A coloured light shows which mode you're in.

Playing with a partner

Onyx+ pairs with other KIIROO devices, including the Pearl and other Onyx models, as well as OhMiBod Fuse and Esca and other FeelTechnology-enabled toys. When your partner uses their toy, Onyx+ responds in real time, whether they're in the next room or another time zone. If your partner wants a toy of their own, the OhMiBod Fuse is one compatible option.

Sleeve, lube and cleaning

Onyx+ uses the RealFeel sleeve. To fit it, take off the cap and the grip clip, slide the sleeve in and close the clip; Kiiroo notes the clip is stiff the first few times. Use plenty of water-based lube inside the sleeve and on yourself. Kiiroo warns that silicone and oil-based lubes damage the sleeve. After use, remove the sleeve, wash it with warm water and a toy cleaner or dish soap, and air-dry it fully. Wipe the casing with cleansing wipes; the device is not waterproof.

Charging and battery

The 1000 mAh battery charges in about four hours through the micro USB port under a rubber cover on the back, and gives roughly an hour of use. A wall adapter isn't included, but a computer port works.

Who it suits

Onyx+ makes most sense if you want a connected toy for long-distance play or interactive content and like a compact, enclosed design. If top speed or a wide choice of sleeve textures matters more, a Keon is the closer match, and if you only want something hand-held, a manual stroker is simpler and never needs charging.
