If you spend more than four hours a day at a keyboard — and let’s be honest, most of us do — the Logitech MX Keys S deserves a serious look. This is Logitech’s flagship productivity keyboard, upgraded from the already-beloved MX Keys with a fresh set of features aimed squarely at power users, multi-device jugglers, and anyone who treats their desk setup like a sacred space. In this Logitech MX Keys S review, we break down everything — from the satisfying low-profile typing feel to the new Smart Actions software — so you can decide if this is the upgrade your workflow has been waiting for in 2026.
The MX Keys S quietly builds on one of the most popular productivity keyboards ever made. It’s not a revolutionary redesign. It’s more like Logitech listened to three years of user feedback, fixed the things people grumbled about, and added a few genuinely clever touches. The result is a keyboard that feels refined rather than flashy — and in the productivity world, that’s exactly the right call.
Quick Verdict

Design and Build Quality
Pick up the Logitech MX Keys S and the first thing you notice is that it feels like a finished product. There’s no flex, no rattle, no hollow plasticky sound when you press a key. The chassis is solid, the low-profile frame sits at a gentle angle that suits long typing sessions, and the spherically-sculpted keycaps are one of those features you don’t fully appreciate until you’ve used them for a week. Each key is concave in a way that cradles your fingertip, reducing lateral slippage and making fast typing feel more controlled.
Logitech made the MX Keys S with recycled plastic and it carries a carbon neutral certification — a genuine sustainability step for a mainstream keyboard, not just a sticker. Available in Graphite and Pale Grey, the aesthetic is clean and desk-friendly without being as aggressively minimalist as, say, an Apple Magic Keyboard. The Graphite version in particular looks premium on any desk setup.
Compared to the original MX Keys, the MX Keys S introduces updated function key labels that reflect modern workflows: there’s a dedicated emoji key, a dictation/microphone key, and revamped media controls. These aren’t just cosmetic — having one-press access to dictation is genuinely useful if you switch between typing and voice frequently. The overall dimensions remain the same full-size layout, which means you get a numpad, but also means this is not a keyboard for cramped desk spaces.
Logitech MX Keys S Review: Performance and Typing Experience
Let’s talk about what actually matters: how does the Logitech MX Keys S feel to type on for hours at a time? The answer is very, very good. The scissor switches are quiet without being mushy. There’s a satisfying tactile feedback on each keypress — not the loud click of a mechanical board, but a confident thud that tells your fingers the key has registered. The travel distance is short (low-profile by design), but Logitech has tuned the actuation point well enough that it never feels like you’re just skating on glass.
Multiple reviewers with hundreds of thousands of combined views have noted the same thing: the MX Keys S feels particularly excellent for long writing sessions. The spherical keycap design is a real ergonomic win. After four hours of continuous typing, finger fatigue is noticeably lower than on flat chiclet-style keyboards. If you’re coming from a laptop keyboard, the MX Keys S will feel like a significant upgrade. If you’re coming from a mechanical board, the trade-off is quieter acoustics and a sleeker profile in exchange for that satisfying clack.
The sound profile deserves a mention. The MX Keys S is keyboard-meeting-appropriate quiet. You can type at full speed during a video call without your colleagues giving you the look. The low-profile switches dampen noise effectively, and there’s very little key rattle. In real-world use — open-plan office, home office, coffee shop — this is one of the quietest full-size keyboards we’ve tested.
Smart Actions: The Feature That Actually Changes Your Day
The headline new feature on the MX Keys S is Smart Actions, accessed through the Logi Options+ software. Smart Actions lets you assign complex, multi-step automations to a single keypress. Think: one button that opens your email client, mutes your mic, and turns off your camera simultaneously. Or a key that launches your project management app and logs your start time. It’s macro functionality with a friendlier UI, and it works well once you’ve spent fifteen minutes setting it up.
The caveat: Logi Options+ needs to be running in the background for Smart Actions to work. On most modern systems, this is a non-issue — it launches at startup and uses minimal resources. But it’s worth knowing that the features aren’t baked into the keyboard firmware itself, so on devices where you can’t install software (a work-locked PC, for instance), you lose access to the advanced customization layer.
Multi-Device Connectivity
The MX Keys S connects to up to three devices simultaneously via Bluetooth and switches between them with a dedicated key on the top row. In testing, the switching is fast — about one to two seconds — and reliable. Using it to hop between a Windows desktop, a MacBook Pro, and an iPad in the same workflow is genuinely seamless. The Logi Bolt USB receiver is also included for environments where Bluetooth is unreliable or restricted, giving you a wired-grade connection without the wire.
Backlighting and Customisation
One of the most-requested upgrades from MX Keys users was proper backlight customisation, and Logitech delivered. The MX Keys S supports per-key backlight control through Logi Options+, allowing you to highlight specific keys, dim others, or set contextual lighting profiles that change based on the active application. It’s not RGB in the gaming sense — the lighting is white — but being able to visually differentiate your shortcut keys from standard typing keys is a legitimate productivity feature.
The smart illumination feature uses a proximity sensor to activate backlighting when your hands approach the keyboard and dim when you step away. It works as advertised and helps extend battery life. That said, if you leave the backlight on continuously, expect around 10 days of use per charge. With backlighting off entirely, the battery can stretch to an impressive five months. The USB-C charging means you can top it up from the same cable as your phone or laptop, which is a small but meaningful daily convenience.
What Real Buyers Are Saying
“I’ve tried six different keyboards in the last two years. This one hasn’t moved off my desk in eight months. The multi-device switching alone is worth the upgrade.” — ⭐⭐⭐⭐⭐ Verified Buyer
“Smart Actions took me 20 minutes to set up and now saves me at least that much every single day. It’s the kind of feature that feels obvious in retrospect.” — ⭐⭐⭐⭐⭐ Verified Buyer
“Bought this for work. Now I use it at home too. Somehow justified buying two. My accountant has questions.” — ⭐⭐⭐⭐⭐ Verified Buyer
And honestly, that last one just about sums up the MX Keys S experience for a certain type of user. It’s the keyboard that makes you want a second one.
MX Keys S vs MX Keys: Should You Upgrade?
If you already own the original MX Keys and are wondering whether the S is worth the switch, the answer depends on how much you’d use the new features. The five key differences are: customizable backlight (original had smart illumination but no per-key control), new dedicated function keys, Smart Actions support, USB-C charging (the original used micro-USB — a genuine quality-of-life upgrade), and improved Logi Options+ integration. For daily drivers who type for a living, the combination of Smart Actions and USB-C alone make the upgrade reasonable. For casual users, the original MX Keys is still excellent and widely available at a lower price.
Against competitors like the Keychron B6 Pro, Dell Premier KB900, and Apple Magic Keyboard, the MX Keys S holds its own through sheer breadth of compatibility and the depth of its software ecosystem. Keychron offers mechanical options that typing enthusiasts will prefer. Apple’s Magic Keyboard integrates more deeply with macOS. But for true cross-platform multi-device productivity, the Logitech MX Keys S available on Amazon sits at the top of the pile.
Value for Money
At its price point, the Logitech MX Keys S delivers a full-size premium keyboard with multi-device Bluetooth, Smart Actions automation, per-key customizable backlighting, USB-C charging, and cross-platform support for Windows, macOS, Linux, and mobile. That’s a comprehensive feature set that justifies the premium tier. You’re not paying for a brand name — you’re paying for a keyboard that’s been refined over multiple generations and that will genuinely improve the efficiency of your daily workflow.
The value case is strongest if you work across multiple devices, rely on keyboard shortcuts, or spend more than four hours a day typing. For those users, the investment pays for itself quickly. If you’re buying a keyboard for occasional use or basic word processing, a mid-range option will serve you fine — but this isn’t that keyboard, and it isn’t trying to be.

Frequently Asked Questions
Is the Logitech MX Keys S compatible with Mac and Windows?
Yes. The Logitech MX Keys S is fully compatible with Windows, macOS, Linux, iOS, Android, and iPadOS. It ships with Windows-standard keycaps but includes Mac-specific key labels, and through Logi Options+ you can remap keys to match macOS conventions. Multi-device switching means you can use it across a Windows PC and MacBook simultaneously without any hardware changes.
What is the difference between the Logitech MX Keys and MX Keys S?
The MX Keys S improves on the original MX Keys in five main ways: per-key customizable backlighting, new dedicated function keys (emoji, dictation), Smart Actions software automation, USB-C charging (replacing the older micro-USB), and improved Logi Options+ integration. The core typing experience and form factor are very similar, making it a meaningful but evolutionary upgrade rather than a total redesign.
How long does the battery last on the Logitech MX Keys S?
With backlight enabled, you’ll get approximately 10 days of use per charge. With the backlight turned off, battery life extends dramatically — up to five months. The keyboard charges via USB-C, so topping it up is simple and fast. The smart proximity sensor helps conserve battery by dimming the backlight automatically when you’re not at your desk.
Does the Logitech MX Keys S work without the Logi Options+ software?
The MX Keys S functions as a standard keyboard out of the box without any software installed. However, Logi Options+ is required to access Smart Actions, per-key backlight customization, advanced key remapping, and multi-device profile management. If you’re using the keyboard on a restricted or locked device where you can’t install software, you’ll still get reliable typing and basic Bluetooth switching, but the advanced feature layer won’t be available.
Is the Logitech MX Keys S good for gaming?
The MX Keys S is designed and optimised for productivity rather than gaming. It lacks anti-ghosting for simultaneous multi-key presses common in gaming, there’s no RGB lighting, no mechanical switches with gaming-tuned actuation, and no dedicated macro modes for gaming peripherals. For everyday productivity, writing, coding, and multi-device work it excels — but dedicated gamers will want to look at purpose-built gaming keyboards instead.
Conclusion
After everything — the typing sessions, the Smart Actions setup, the multi-device switching back and forth between machines — the Logitech MX Keys S earns its reputation as the gold standard for wireless productivity keyboards. It’s not trying to be a mechanical keyboard for enthusiasts, and it’s not trying to be the cheapest option in the category. It’s trying to be the best keyboard for people who get things done, and it largely succeeds.
The Smart Actions feature alone can reclaim meaningful time each week. The per-key backlight customization finally gives power users the control they’ve been asking for. The USB-C charging is the small-but-important upgrade that removes a daily friction point. And through all of it, the typing experience remains genuinely excellent — quiet, accurate, and comfortable enough for marathon sessions without complaint.
If you’re building or upgrading a serious desk setup in 2026, the Logitech MX Keys S belongs on your shortlist. Check the current price on Amazon and see if it’s the right fit for your workflow.
