Mechanical Magnetic Keyboard Keychron K4H-F1 — 96% form factor, QWERTY, USB + RF Wireless + Bluetooth, 100 keys, RGB, Black

Keychron K4 HE is a fully customizable 96% wireless keyboard that combines magnetic switch technology with a compact layout and wood-accented design. Available in Special Edition (white or black with natural rosewood accents and aluminum frames) and Standard Version (aluminum frames), the K4 HE uses Gateron double-rail magnetic switches with advanced TMR sensors to measure actuation depth and deliver precise, low-latency input. The keyboard supports 2.4 GHz (1000 Hz), Bluetooth 5.2 multi-device pairing, QMK firmware, hot-swappable magnetic switches, and offers north-facing RGB backlighting and durable double-shot PBT keycaps.

Advantages

Magnetic switches with dedicated TMR sensors allow adjustable actuation from 0.2 to 3.8 mm with 0.1 mm sensitivity, giving fine-grained control over key response for both gaming and typing. Dynamic features such as Last Key Priority (LKP), Snap Click, Dynamic Keystrokes (DKS), Dynamic Rapid Trigger and Analog Mode enable layered inputs, variable control like a gamepad, and immediate reactions based on travel depth. Pre-lubed Gateron switches, multiple internal foam layers and a silicone pad improve acoustic quality and typing feel. The keyboard is compatible with macOS and Windows via a system toggle and includes alternative keycaps for each platform.

How to use

Connect the keyboard via USB-C for wired mode or switch to 2.4 GHz or Bluetooth 5.2 for wireless use. Use the system toggle to switch between macOS and Windows layouts and install the Keychron Launcher web app to remap keys, program macros, and adjust RGB settings. Adjust actuation points per key through the firmware or Launcher to set desired press depths for different actions. For Analog Mode and depth-based features, configure the sensitivity and behavior in the Launcher or via QMK settings to match game or application requirements. Replace magnetic switches by pulling out the existing switch and inserting a compatible magnetic switch while the keyboard is powered off.

Recommendations

For competitive gaming, use 2.4 GHz mode at 1000 Hz and set shallower actuation points for rapid response; for typing or content work, increase actuation depth for deliberate input and enable acoustic dampening features. Keep the keyboard firmware and Keychron Launcher up to date to access new features and stability improvements.
