Logitech MX Keys S Combo Review
A typist's dream keyboard and mouse pair that just works across every device you own.
If you bounce between a laptop, a desktop, and the occasional iPad, the MX Keys S Combo lets you type and click across all of them without lifting a finger to repair. That's the whole pitch, and it delivers.
What the MX Keys S Combo actually is
This is Logitech pairing two of its most popular productivity peripherals: the MX Keys S full-size keyboard and the MX Master 3S mouse. You can buy each separately, but the combo bundles them at a small discount and ships them with the Logi Bolt receiver and Logi Options+ software baked into the experience.
Pricing lands roughly in the $180 to $230 range on Amazon depending on color and sales. That's premium territory for a wireless keyboard and mouse, and Logitech knows it. The justification is connectivity, build, and the ecosystem glue that ties three computers together.
Typing feel and the mouse that everyone copies
The MX Keys S uses low-profile scissor switches with subtly dished keycaps. The result is quiet, stable typing that feels closer to a good laptop keyboard than a clacky mechanical board. Backlighting is smart too, with proximity sensors that light the keys as your hands approach and dim to save battery when you walk away. Touch typists tend to love it. People chasing the tactile thump of a Cherry MX board will find it flat and uneventful by comparison.
The MX Master 3S is the real star and arguably the best productivity mouse on the market. The MagSpeed metal scroll wheel ratchets for precision then free-spins to fly through long documents, and the 8,000 DPI sensor tracks fine on glass. Logitech also dropped the click noise way down from older Master models, so it's office-meeting quiet. The shape suits medium to large hands and right-handers only. Lefties are out of luck.
Logitech Flow is the feature that earns the price
Here's where this combo separates from a generic wireless set. With Logi Options+ and Flow, you can link up to three computers and move your cursor from one screen to the next as if they were one machine. Push the pointer past the edge of your laptop and it jumps to your desktop. Copy text on a Mac, paste it on a Windows PC. It works across operating systems, which still feels mildly magical years after Logitech introduced it.
Battery life is a non-issue. The keyboard runs around ten days with backlighting on and months with it off, and both devices charge over USB-C. A quick top-up gives you hours of use. You won't be hunting for AA batteries, and you won't be tethered while it charges.
The honest downsides
Options+ is functional but can be sluggish and occasionally needs a restart to recognize a device. It's the weakest part of an otherwise polished product. The keyboard has no dedicated number pad layout choices beyond full-size, so small-desk users may want the MX Keys Mini instead. There's no Bluetooth-only purist option here either, though the Bolt receiver is reliable.
And the obvious one: the price. You can get a perfectly good wireless keyboard and mouse for a third of this. The combo only makes sense if you'll actually use the multi-device features and you spend serious hours at a keyboard.
Who should buy it, who should skip it
Buy it if you juggle multiple computers, write or code all day, and want hardware that feels worth keeping for five years. Remote workers with a personal and a work laptop get the most out of Flow. It's also a clean, low-profile setup for anyone who hates desk clutter.
Skip it if you're a gamer needing high polling rates and mechanical feedback, if you're left-handed, or if you mostly browse and email on one machine. In those cases you're paying for capability you'll never touch. The verdict: this is the productivity desk default for good reason, and most people who buy it stop shopping for replacements.
Frequently asked questions
- Does the MX Keys S Combo work with both Mac and Windows?
- Yes. Both devices support macOS, Windows, Linux, ChromeOS, iPadOS and Android. The keycaps show both Mac and Windows symbols, and Logitech Flow can copy and paste between a Mac and a PC at the same time.
- Is it Bluetooth or does it need the USB receiver?
- It does both. You can connect over Bluetooth Low Energy or use the included Logi Bolt USB-C receiver. The Bolt connection is generally more stable and supports the multi-device Flow feature.
- Is the MX Keys S Combo worth it over buying the keyboard and mouse separately?
- Slightly. The combo usually costs a bit less than buying both individually, and you get the same MX Keys S and MX Master 3S. If you only need one of the two, buy that one alone.
