Keychron K4 HE Wireless

Manufacturer: Keychron

The Keychron K4 HE Wireless is a 98% full-size gaming mechanical keyboard that combines wireless flexibility with advanced switch technology. Built around Gateron Double-Rail Magnetic Nebula Hall effect switches, it supports tri-mode connectivity via Bluetooth 5.2, 2.4GHz wireless, and USB, making it adaptable to a wide range of setups including Mac-oriented configurations. The aluminum and plastic case gives it a solid build, while hot-swap support allows switch changes without soldering.

On the feature side, the K4 HE offers rapid trigger and adjustable actuation with a range spanning 0.2 mm to 3.8 mm, alongside dual actuation and analog input support — capabilities typically associated with competitive gaming use. It carries full NKRO, and is compatible with QMK, ZMK, and VIA for extensive customization. The keyboard runs for up to 110 hours on a single charge, uses north-facing RGB backlighting on double-shot PBT shine-through keycaps, and operates at a 1000 Hz polling rate. A one-year warranty and detachable cable are also included.

Pros
  • Actuation distance is adjustable between 0.2 mm and 3.8 mm, with rapid trigger and dual actuation support offering precise control over keypress registration
  • Hot-swappable Hall effect switches allow replacement without soldering, and the linear Gateron Double-Rail Magnetic Nebula switches require no physical contact to actuate
  • Tri-mode connectivity via Bluetooth 5.2, 2.4GHz wireless, and USB provides flexibility across different setups, including Mac-compatible configurations
  • A 110-hour battery life allows extended use without frequent recharging
  • Full NKRO ensures every simultaneous keypress is individually recognized
  • QMK, ZMK, and VIA support offer broad firmware and keymap customization options
Cons
  • At 1090 g, the keyboard is relatively heavy, which may be a concern for portability
  • No wrist rest is included, requiring a separate purchase for users who need wrist support
  • Media controls are only accessible via the Fn key, with no dedicated media keys or rotary dial available
  • USB passthrough is absent, limiting the ability to connect additional peripherals directly through the keyboard
  • The case is only available in black, offering no color variety
  • The warranty period covers only one year
Who is this for?

This keyboard is well-suited to users who want granular control over their input, particularly those who rely on rapid trigger and adjustable actuation for fast, precise keypress registration. The tri-mode wireless connectivity and 110-hour battery life make it a strong fit for those who prefer a clean, cable-free desk setup without sacrificing responsiveness. Users who like to customize their firmware will also find the QMK, ZMK, and VIA compatibility especially useful, and the hot-swappable Hall effect switches cater to those who enjoy tuning their switch feel over time.

Who is this NOT for?

At 1090 g and with no color options beyond black, this keyboard is not a natural fit for users who prioritize portability or personalized aesthetics. Those who depend on dedicated media keys or a rotary dial for quick audio and playback control will find the Fn-layer-only approach less convenient. It is also not ideal for users who need USB passthrough to connect peripherals directly through the keyboard, or for those who prefer a broader ecosystem of case colors and included accessories such as a wrist rest.
