Logitech MX Keys S Combo Review (2026): Polished Desk Duo

This Logitech MX Keys S Combo review looks at a desk bundle built around one idea: make long typing and mouse sessions comfortable, and make it easy to move between computers. The box holds the MX Keys S keyboard, the MX Master 3S mouse, an MX Palm Rest and a Logi Bolt USB receiver. It sits in the mid-range part of the market, and it suits office workers who juggle several machines and care more about typing comfort than about weight or a metal chassis. This review is based on manufacturer specs and what independent experts report, not on hands-on testing.

What you get in the box

The combo is a complete work setup rather than a single peripheral. You get the keyboard, the MX Master 3S mouse, the palm rest and the Logi Bolt receiver, and the combo can also connect over Bluetooth Low Energy. It comes in Graphite or Black.

Reviewers generally point out that the bundle costs less than buying the parts separately. They also note that the saving is modest, so the case for the combo rests on whether you want all three pieces, not on a big discount. If you already own a mouse you like, it's worth weighing that before buying.

Design and build

The keyboard uses spherically-dished, low-profile keys, designed for fast, fluid and quieter typing. Reviewers praise typing that is comfortable, accurate and quiet, which matters in shared offices and for anyone who types for hours.

The physical package is a different story. The keyboard measures 16.94 in x 5.18 in x 0.81 in (430.2 x 131.63 x 20.5 mm) and weighs 28.57 oz (810 g). A common criticism is that the keyboard is heavy and all plastic, with some owners reporting creaking. If you want a lightweight board to carry around, or a metal-built one, this is not it.

The included MX Palm Rest is there for wrist comfort. If you are building out a whole workspace, our guide to the best office chairs covers the seating side.

The MX Master 3S mouse measures 4.92 in x 3.32 in x 2.01 in (124.9 x 84.3 x 51 mm) and weighs 4.97 oz (141 g). It has 7 buttons. One limitation to know about: reviewers note that it is right-handed only, so left-handed users should look elsewhere.

Features and what they mean day to day

Smart illumination

The backlight turns on as your hands approach and adapts to the light in the room. That means the keys light up as you reach for them, whatever the lighting in the room. Reviewers praise this, though the battery section below explains the trade-off.

MagSpeed scroll wheel

The mouse's MagSpeed wheel scrolls at 1,000 lines per second. That helps with long documents, spreadsheets and code. Reviewers also praise the wheel and the quiet clicks, which fits the keyboard's quieter character.

Tracking

The mouse has an 8K DPI Darkfield sensor, with a range of 200 to 8000 dpi, and it tracks even on glass. That is handy if your desk is glass or you work in places with awkward surfaces. This is an office mouse, though, and the verdict is clear that it is not aimed at gamers.

Multi-device and cross-platform use

Multi-device use is one of the combo's main features. The combo pairs with up to 3 devices over Bluetooth LE or the included Logi Bolt USB receiver. They work across Windows, macOS, Linux, ChromeOS, iPadOS and Android, and Flow lets you move between computers. If your day involves several computers or devices, you can keep one keyboard and mouse and switch between them rather than reaching for different peripherals.

Smart Actions and Logi Options+

Smart Actions in Logi Options+ let you automate repetitive tasks with one keystroke. That is useful for people with routine workflows. A common criticism, however, is that Logi Options+ can be slow and buggy. Since customisation runs through that software, it is worth knowing before you count on it.

Battery and connectivity

The keyboard has a 1500 mAh Li-ion polymer battery and charges over USB-C. Its battery life is up to 10 days with the backlight on, or up to 5 months with the backlight off. That gap is the thing to understand. If you leave the smart backlight active, you will be charging roughly every 10 days at best, and reviewers call this out as a drawback. If you type in a well-lit room and turn the backlight off, charging becomes an occasional chore.

The mouse is easier to live with, at up to 70 days of battery life.

For connections, you have the choice of Bluetooth Low Energy or the Logi Bolt receiver. Bluetooth saves a USB port, while the receiver is there if you prefer a dedicated link or your computer has no Bluetooth. The combo comes with a 1-Year Limited Hardware Warranty.

What experts like and what they criticise

The combo averages 8.5/10 across 3 expert reviews: XDA Developers scores it 9/10, Mezha 8.5/10 and CGMagazine 8/10. It has also been recommended in 7 expert guides.

What reviewers praise:

• Comfortable, accurate and quiet typing from the low-profile dished keys
• The smart backlight that wakes as your hands approach and adjusts to the room
• The MX Master 3S's fast MagSpeed wheel and quiet clicks
• Pairing with up to 3 devices across Windows, macOS, Linux and mobile
• The included palm rest

What reviewers criticise:

• The premium price, with only modest savings over buying the parts separately
• A heavy, all-plastic keyboard, with some reports of creaking
• The keyboard's battery life of about 10 days with the backlight on
• Logi Options+ being slow and buggy, and a mouse that is right-handed only

Who should buy it

The combo fits people who spend most of their day typing and moving between machines. Office workers who split time between a work computer and a personal one, or between Windows and macOS, will get the most from the 3-device pairing and Flow. It also suits anyone who wants a quieter keyboard and mouse and values wrist comfort.

It makes sense if you want the whole set in one purchase. Buying the keyboard, mouse and palm rest together is simpler, and the bundle is cheaper than the parts bought separately.

Who should skip it

Skip it if you want a lightweight keyboard or a metal-built one. Skip it if you are left-handed, since the mouse is right-handed only, or if you want a gaming mouse. Anyone who dislikes charging devices will also find the backlit battery life of about 10 days annoying, although turning the backlight off stretches it to up to 5 months. If you already own a mouse you are happy with, the modest saving from the bundle may not justify the premium price.

How it fits in its category

Its appeal is in the details: the dished keys, the adaptive backlight, the scroll wheel and the ability to hop between computers. Its drawbacks are price, weight and software that can be slow and buggy. If you are furnishing a full workspace, our look at the Herman Miller Embody covers a premium chair for the same kind of long working day.

Verdict

The Logitech MX Keys S Combo is a well-rounded work bundle that does what it is meant to do: make typing quiet and comfortable and make switching between devices painless. Its 8.5/10 expert average and 7 expert-guide recommendations back that up. The compromises are real, though. It is heavy, mostly plastic, needs frequent charging with the backlight on, and depends on software that some people find frustrating. If you work across several computers and want a comfortable, quiet setup, it is an easy recommendation. If you prize low weight, metal construction or a left-handed or gaming mouse, look elsewhere.
