The Logitech MX Keys S is a wireless keyboard that continues Logitech's MX Keys lineup. Like the previous generation Logitech MX Keys, this keyboard has a low-profile design, and the keycaps have a spherical dish-shape profile that can help keep your fingers centered and reduce accidental keystrokes. It also features the same full white backlighting as its predecessor that can automatically illuminate when your hands are near but introduces a new feature that adjusts the backlighting by default according to the lighting conditions around you. Other changes include a different set of shortcuts on the function row that now includes an emoji key. Logitech has also added new software functionality for controlling the keyboard's backlighting and creating macros.
Unlike its predecessor, which connects wirelessly via Bluetooth or with the Logitech Unifying receiver, this keyboard connects wirelessly via Bluetooth or with the Logi BOLT receiver. For more details, see the Wireless Versatility test below.
Our Verdict
The Logitech MX Keys S isn't designed for this use but is very good for casual gaming. It feels well-built, and the low-profile design is comfortable to use without a wrist rest. That said, while the latency is decent for playing casual games in any genre, it's too high for playing fast-paced or competitive games.

The Logitech MX Keys S is decent for use with mobile or tablet devices, but it's heavier and considerably larger than keyboards designed specifically for this use.

The Logitech MX Keys S is an impressive keyboard for programming. It has great build quality, and its low profile design means it's comfortable to use without a wrist rest. It also has per-key backlighting and pairs wirelessly with up to three devices simultaneously. That said, this keyboard has no dedicated macro keys, and while you can record macros (called Smart Actions) using the software, there are some limitations on their complexity. Additionally, by default, shortcuts like media controls and the emoji button are the primary functions on the F-row rather than F1-F12, but you can reverse this behavior with an option in the software or the Fn lock hotkey on the keyboard itself.
- Impressive build quality.
- Low profile design is comfortable without a wrist rest.
- Connects via Bluetooth or Logi BOLT receiver and can pair with up to four devices simultaneously.

Popular Keyboard Comparisons
This keyboard is an outstanding desktop option for productivity and everyday browsing. It has excellent wireless versatility, provides great typing quality, and has a slim profile that makes it comfortable to use without a wrist rest. It's also extremely quiet, especially compared to mechanical keyboards.
The Logitech MX Keys S continues Logitech's MX keys lineup. Unlike the original Logitech MX Keys, which connected via Bluetooth or with the Logitech Unifying USB Receiver, this keyboard connects wirelessly using Bluetooth or the Logi BOLT USB receiver that Logitech advertises as providing better security and wireless stability than a standard Bluetooth connection. The primary hardware difference with this new model includes a different set of default shortcuts on the F-row at the top of the keyboard, including a new emoji key. This keyboard also has a new backlighting feature that adjusts the brightness depending on the lighting in your surroundings. Additional changes add new software functionality with this version, allowing more control over the backlighting and support for creating macros, which Logitech calls Smart Actions. However, it's worth noting that Smart Actions are now supported on the previous generation Logitech MX Keys, so this isn't unique to the new model.

The Logitech MX Keys S is a newer version of the Logitech MX Keys. The MX Keys S only has minor physical differences in its shortcuts on the F-row. It also has an auto-brightness feature that adjusts the backlighting according to your environment, and it provides more options for customizing the backlighting using the software, while the older MX Keys only allows you to toggle the lighting on or off. The other major difference is that the MX Keys S connects wirelessly via Bluetooth or with the Logi BOLT receiver. In contrast, the older MX Keys connects wirelessly via Bluetooth or the Logitech Unifying Receiver.
The Logitech MX Mechanical and the Logitech MX Keys S are wireless full-size keyboards with low-profile designs. The MX Mechanical uses mechanical switches and can be purchased with tactile Brown or clicky Blue switch varieties. On the other hand, the MX Keys S has tactile scissor switches, which are quieter.
The Logitech MX Keys S and the Logitech Signature Slim Keyboard K950 are similar low-profile, wireless keyboards designed for productivity and everyday desktop use. The MX Keys S offers a more premium-feeling build quality and typing quality. Its keycaps, in particular, feel higher quality and have small dish-shaped tops that help better center your fingers while typing. It also has full white backlighting with shine-through keycaps. On the other hand, the Signature Slim Keyboard K950 has cheaper feeling materials and flat keycaps. It also lacks backlighting, and unlike the MX Keys, which recharges with a USB cable, the SIgnature K950 uses replaceable AAA batteries.
The Logitech MX Keys Mini is essentially a smaller variant of the Logitech MX Keys S. The MX Keys Mini has a compact (75%) form factor, while the MX Keys S is a full-size model. The MX Keys S also has a backlighting feature that adjusts the backlight brightness depending on your environment. Both keyboards connect wirelessly via Bluetooth and are compatible with the Logi BOLT USB receiver. However, while the BOLT receiver is included in the box with the MX Keys S, it's sold separately for the MX Keys Mini.
