Logitech MX Keys S Wireless Keyboard Review

What the Logitech MX Keys S Actually Is

The MX Keys S is Logitech's flagship low-profile wireless keyboard, aimed squarely at people who spend their day typing — writers, coders, project managers, and anyone juggling three browser tabs and a meeting. It's a full-size layout with a number pad, spherically dished keys, and a sturdy aluminum top plate that gives it a reassuring, planted weight on the desk.

It's an iterative update to the original MX Keys rather than a reinvention. The headline change is Smart Backlighting that uses a proximity sensor to light up as your hands approach and dim to save power when you walk away. You connect over Bluetooth or Logitech's Bolt USB receiver, and it pairs to three devices with dedicated switch keys — handy if you bounce between a work laptop, a personal machine, and a tablet.

How It Performs Day to Day

The typing experience is the whole pitch, and it delivers. The scissor switches have a short, crisp travel with just enough tactile feedback to feel deliberate, and the dished keycaps subtly guide your fingertips so you make fewer fat-finger mistakes. After a few hours you stop noticing the keyboard, which is exactly what you want.

It's genuinely quiet — closer to a soft thock than a clatter — so it won't annoy a partner on a late-night deadline or broadcast your typing speed on a video call. Switching between paired devices is near-instant, and the USB-C charging means a quick top-up gives you days of use. Logitech's Options+ software lets you remap the function row and set per-app shortcuts, though it's optional; the keyboard works fine out of the box.

The Pros and Cons That Matter

Pros: excellent, low-fatigue typing feel; quiet keystrokes; rock-solid build; multi-device switching that just works; useful backlighting; and battery life measured in weeks (or longer with backlighting off). It plays nicely with both Windows and macOS, with the keycaps labeled for both.

Cons: there's no Bluetooth/Bolt toggle — you pick a connection method per slot, which can confuse first-timers. The keyboard has no tilt-angle adjustment beyond its fixed low profile, so people who love a steep typing incline won't find it here. And while it's well-priced for what it is, it's still a premium purchase compared to a basic membrane board.

Who It's For — and Who Should Skip It

Buy it if you're a heavy typist who values comfort, quiet, and the ability to flip between multiple computers without re-pairing. It's a natural pairing with Logitech's MX Master mice and a smart upgrade for anyone tired of a cramped or rattly laptop keyboard.

Skip it if you're a gamer chasing fast mechanical actuation and per-key RGB — this isn't built for that. Also pass if you want an ergonomic split layout (look at the MX Keys S's ergo siblings instead) or if you simply don't type enough to justify spending in the roughly $90–$120 range.

The Verdict

The Logitech MX Keys S is one of the easiest productivity keyboards to recommend. It nails the fundamentals — feel, quietness, build, and seamless multi-device use — without gimmicks. For desk-bound professionals, it's worth the premium over a budget board, and it should last for years.
