## Summary description

Keychron K4 HE is a compact mechanical keyboard with universal use, offering wired and wireless connectivity (USB, RF Wireless and Bluetooth).

## Long description

Keychron K4 HE is a compact 96% wireless mechanical keyboard that combines magnetic Hall Effect switch technology with a minimal design and natural rosewood accents. Available in Special and Standard editions, it supports wired USB-C, 2.4 GHz RF, and Bluetooth 5.2 connections, a 1000 Hz polling rate in wired and 2.4 GHz modes, QMK firmware compatibility, and a configurable web-based Keychron Launcher for actuation, remapping, and macros. The keyboard includes pre-lubed Gateron double-rail magnetic switches, adjustable actuation points, analog mode, Dynamic Rapid Trigger and Dynamic Keystrokes for multiple actions per key, north-facing RGB backlighting, hot-swappable magnetic switches, and sound-dampening foams for improved acoustics.
Advantages
The K4 HE delivers precise, adjustable key response by using magnetic Hall Effect sensors that allow actuation point tuning from 0.2 to 3.8 mm with 0.1 mm increments. Its Dynamic Rapid Trigger and Last Key Priority features improve responsiveness in fast-paced gaming, while Analog Mode and Dynamic Keystrokes enable variable inputs and up to four actions per key based on press depth. The keyboard offers wide connectivity—USB-C, 2.4 GHz RF with 1000 Hz polling, and Bluetooth 5.2 for multi-device pairing—and is programmable via open-source QMK firmware and the web-based Keychron Launcher. Built-in acoustic foams and pre-lubed switches provide a quieter, thocky typing sound, and double-shot PBT keycaps resist wear and oiling.
Suitable for
Competitive and casual gaming where fast, precise inputs are required
Productivity and typing tasks requiring durable keycaps and adjustable feedback
Multi-device workflows across Windows, macOS, Linux, tablets, and phones
Users who customize keymaps, macros, and actuation via QMK or Keychron Launcher

How to use
Connect the keyboard to a device using USB-C for wired mode, pair via the included 2.4 GHz dongle for low-latency wireless, or use Bluetooth 5.2 to connect up to three devices. Install or open the Keychron Launcher web app in a supported browser to remap keys, set actuation points, assign macros, and configure RGB lighting. Use the system toggle and extra keycaps to switch between Windows and macOS layouts and save separate layouts on the keyboard. Adjust actuation depth per key directly in the Launcher or via QMK for tailored input response.
Usage recommendations
For gaming that requires rapid, repeatable inputs, use the 2.4 GHz mode with 1000 Hz polling and enable Last Key Priority and Dynamic Rapid Trigger. For nuanced control in racing or simulation titles, enable Analog Mode and configure Dynamic Keystrokes to assign multiple actions per key based on press depth. Use the Keychron Launcher to fine-tune actuation points at 0.1 mm increments to balance accidental activation and response speed.
