The Keychron B31 is a compact 75% wireless keyboard designed for users who want a quiet, stable typing experience with versatile connectivity. It suits office workers, students, or anyone needing a low-noise keyboard that works seamlessly across multiple devices. Its scissor-switch keys offer a different feel from mechanical switches, focusing on smoothness and silence rather than tactile feedback or key swapping.
The B31 uses an enhanced scissor mechanism that is taller than standard designs, providing more stable and accurate keystrokes. Keys come fully pre-lubed to reduce friction, resulting in a smooth and very quiet typing feel. This makes it suitable for shared spaces or late-night use. Keycaps are not replaceable, which limits customization options. The keyboard supports key remapping and macros through its web-based launcher app.
This keyboard offers three connection modes: 2.4 GHz wireless with a plug-and-play receiver, Bluetooth 5.2 for multi-device use, and wired USB-C for stable, low-latency connections and charging. Switching between devices and connection types is straightforward, making it flexible for various setups.
The B31 supports Windows and macOS layouts, with a toggle to switch between systems and separate keymaps for each. Its configuration software works on macOS, Windows, and Linux, allowing users to customize key functions and shortcuts. Multimedia and function keys can be toggled via a shortcut for convenience.
The keyboard has an ABS plastic case and keycaps, which keeps it lightweight but less durable than metal alternatives. Adjustable typing angles help reduce wrist fatigue during long sessions. The slightly taller keycaps also contribute to a more comfortable and stable typing posture.
