Power up your performance with MX Keys S and MX Master 3S. Comfort, stability, and precision combined in a pairing that helps you  master your flow all day long.

Key Features

Combined for more comfort and deeper focus
MX Keys S and MX Master 3S are designed to keep you comfortable and in the flow for hours.

MX Keys S is crafted with a low-profile design and an optimum keyboard angle that encourages better wrist posture and reduces joint strain. The MX Master 3S is designed with a tilt angle that lets you keep your arms in a more natural posture while ideally positioned buttons allow for quick and intuitive navigation.

The combo also includes a palm rest to reduce pressure on the wrist for all-day comfort.

Fast fluid precision typing
Work for hours with more precision and speed with spherically-dished keys that match the shape of your fingertips, minimizing the chances of a mistype and providing satisfying feedback, while increased key stability reduces noise.

The rounded edges provide satisfying feedback — no matter where you strike the key. Matte coating has been applied to every key so your fingers glide effortlessly over the surface.

Scroll 1,000 lines per second and track on any-surface
Introducing MagSpeed scroll wheel: Effortlessly scroll through 1,000 lines per second with hyper-fast mode which is up to 90% faster[1]. And ratchet mode is 87% more accurate[2] so you can truly stop on a pixel

The 8K DPI optical sensor on MX Master 3S lets you track anywhere – even on glass[3]. High DPI tracking means you can cover more ground with subtle movements – perfectly suited for work on high-resolution monitors.


Smart illumination made smarter
Day or night, MX Keys S is here for you whenever inspiration sparks.

For those burning the midnight oil, the keyboard includes proximity sensors that light up the keys the moment your hand's approach. The backlit keys automatically adjust to suit changing lighting conditions and fade when you leave the desk — saving power for those moments of inspiration. With Logi Options+[4], you now have more flexibility with adjusting backlighting duration and brightness.

USB-C quick charging, Long-lasting
Use the included USB-C charging cable or any other USB-C cable to top up the power while you work for a full day of non-stop performance.

For MX Keys S – when on, automatic backlighting presets can preserve battery power by turning itself off in bright environments[5]
