Description

The Keychron K2 HE is a breakthrough in keyboard tech, blending precision and customization into a sleek 75% form-factor. Its Hall‑Effect magnetic switches use sensors instead of traditional contacts, enabling micro‑adjustable actuation points alongside an ultra-fast Rapid Trigger—ideal for both competitive gaming and fast typing

It supports analog-like input through dynamic keystrokes, allowing up to four actions per key depending on press depth. The hot-swappable design and pre-lubed Gateron switches deliver smooth feel and easy customization.

Wireless performance is top-notch with 2.4 GHz (1000 Hz polling), Bluetooth 5.2 (multi-device), and USB‑C wired (1000 Hz). The open‑source QMK firmware and Keychron Launcher web app let you reassign keys, adjust actuation depth, lighting modes, macros, and more.

Built with double‑shot PBT keycaps, an aluminum plate, wooden side accents, and layered foam/EPDM for a satisfying “thocky” feel, the K2 HE received a 9/10 review rating from WIRED, praised for its value and feel. It also earned recognition for its magnetic switches suitable for gaming by outlets like Tom’s Guide and Phandroid.
