Typing Experience
The MX Keys S uses Logitech’s low-profile Perfect Stroke design. The keys are spherically dished to guide your fingertips toward the center, while the scissor mechanism provides short, controlled travel. This makes the keyboard especially appealing for users who prefer a laptop-like feel but want a full-size desktop layout and number pad.
Smart Backlighting
Built-in proximity sensors can illuminate the keys as your hands approach, while ambient-light sensing adjusts brightness to the room. Backlighting can also be customized through Logitech’s software, giving users more control over the keyboard’s lighting behavior.
Three-Device Easy-Switch
Easy-Switch keys let the MX Keys S connect to and move among up to three compatible computers or devices. This is useful for anyone who regularly works across a desktop, laptop, or tablet and wants one keyboard instead of separate peripherals for each system.
Bluetooth and Logi Bolt Connectivity
The keyboard supports Bluetooth Low Energy as well as Logitech’s Logi Bolt wireless connection. This flexibility makes it easier to integrate the MX Keys S into different desk setups while maintaining a wireless workspace.
Battery Life and USB-C Charging
Logitech rates the rechargeable battery for up to 10 days on a full charge with predefined backlighting settings, or up to five months when backlighting is switched off. Actual battery life varies with lighting level, usage, and computing conditions. The keyboard recharges over USB-C and can continue working while connected for charging.
Productivity Features
MX Keys S includes productivity-oriented keys and works with Logi Options+ for customizable shortcuts and actions. For users already invested in compatible Logitech MX devices, the software can help create a more integrated multi-device workflow.
