Keychron K2 HE review

The K2 HE is the keyboard we would point most first-time buyers to, because it covers typing and gaming without forcing a choice. Keychron fits Gateron Double-Rail magnetic switches that measure key travel, which unlocks Rapid Trigger and actuation points you can set per key from 0.2 to 3.8 mm in 0.1 mm steps. That means a light press for games and a deeper, more deliberate one for writing. It connects over 2.4 GHz at 1000 Hz, Bluetooth 5.2 to three devices, or a USB-C cable, and the 4000 mAh battery is rated for up to 110 hours. QMK firmware and the browser-based Keychron Launcher handle remapping and macros on macOS, Windows and Linux, and the box includes keycaps for both Mac and Windows. The trade-offs: the switches are hot-swappable only with Gateron Double-Rail magnetic switches, Bluetooth polls at just 125 Hz, and there is no number pad.
