Keychron Q4 HE QMK Wireless

Manufacturer: Keychron

The Keychron Q4 HE QMK Wireless is a compact 60% keyboard built for users who want a serious typing and gaming setup without sacrificing desk space. It sits in an aluminum case with a gasket mount construction, available in black or white, and supports wireless use over Bluetooth 5.2 or 2.4GHz alongside a wired USB connection. With a rated battery life of 100 hours, it handles extended wireless sessions without frequent recharging, and the detachable cable adds flexibility for wired use.

At its core, the Q4 HE runs Gateron Double-Rail Magnetic Nebula Hall effect switches with a linear feel, offering an adjustable actuation range between 0.2 mm and 3.8 mm and a 60 g actuation force. Rapid trigger, dual actuation, and adjustable actuation are all supported, giving users fine-grained control over how the switches respond. The keyboard is fully hot-swappable, QMK and VIA compatible, and includes N-key rollover. Keycaps are double-shot PBT in an OEM profile with south-facing RGB backlighting, and the layout follows the standard ANSI United States arrangement. It weighs 1415 g and measures 303.07 × 121 × 32.78 mm.

  • No dedicated media keys or rotary dial are included for quick audio or playback control
  • At 1415 g, the keyboard is relatively heavy for a compact 60% form factor

  • The warranty period covers only one year
Who is this for?

This keyboard suits users who want a compact 60% footprint without giving up advanced input features, particularly those who benefit from rapid trigger and adjustable actuation for precise, responsive keystroke control. The tri-mode wireless connectivity and 100-hour battery life make it a practical fit for those who prefer a cable-free desk setup or switch between multiple devices. Its QMK and VIA support also makes it well-suited to enthusiasts who want deep customization over layouts and firmware behavior.

Who is this NOT for?

Users who rely on a full set of keys for productivity tasks will find the 60% layout limiting, as there are no dedicated function row, navigation cluster, numpad, or media keys available. Those who prioritize portability may be put off by the 1415 g weight, which is substantial for a compact keyboard. Additionally, users who prefer wireless-first firmware customization through ZMK, or who need USB passthrough for peripheral connectivity, will find those capabilities absent here.

Final Verdict

The Keychron Q4 HE QMK Wireless delivers a well-rounded package for users who want a compact keyboard with genuinely advanced input capabilities.

The aluminum construction and hot-swappable switch support further reinforce its position as a thoughtfully built option for enthusiasts.
