Keychron K4 HE Special Edition Wireless Mechanical Gaming Keyboard, Magnetic, Black, Wood

The Keychron K4 HE Special Edition is a 96% keyboard designed for gaming and typing, featuring an ISO layout and a dedicated numeric keypad. It uses Gateron Double-Rail magnetic switches with Hall effect sensors instead of standard contact points. Actuation depth is adjustable from 0.2 mm to 3.8 mm. Users can configure rapid-trigger settings to reset keystrokes dynamically for faster input. Connectivity includes wired USB-C, 2.4 GHz wireless, and Bluetooth 5.2. The included 2.4 GHz receiver offers lower latency for gaming, and multi-device support allows pairing with several hosts simultaneously.

The chassis has a black ABS housing, an aluminium frame, and natural wood accents. The OSA-profile keycaps are made from double-shot PBT plastic to resist wear. Customisation is managed via QMK firmware and the Keychron Launcher web app, allowing users to remap inputs, program hotkeys, and assign analog-style commands. Integrated feet allow for height adjustment. The internal battery is charged via a detachable cable. The keyboard is compatible with Windows, macOS, Linux, iOS, and Android.
