Keychron K4 HE Wireless Mechanical Gaming Keyboard, Gateron Double-rail Magnetic, Black

The Keychron K4 HE is a wireless, hot-swappable keyboard designed for gaming and intensive typing. It uses Gateron double-rail magnetic switches instead of standard contact points. These sensors track key travel, allowing users to set the registration point between 0.2 mm and 3.8 mm. A shorter distance enables faster response times, while a longer distance helps prevent accidental keystrokes. The keyboard supports features such as Rapid Trigger and dynamic keystrokes, and its aluminium frame ensures structural stability.

Compatible with Windows, macOS, and Linux, the keyboard fits easily into most workspaces. Its 96-percent layout includes a numeric keypad while maintaining a compact footprint. The double-shot PBT keycaps are resistant to the shine that develops from daily use. Users can swap the Hall-effect switches without soldering, and custom macros or hotkeys can be configured using QMK software.
