Keychron K4H 96% RGB Wireless Hall-Effect Keyboard - Gateron Nebula Switch

Keychron K4 HE

A fully customizable 96% layout wireless keyboard with magnetic switches — a breakthrough in switch technology that uses magnetic sensors instead of physical contacts to measure actuation depth. This puts you in total control over the response of each and every switch.

The Fully Assembled Version Includes:

• The keyboard PCB, the case, and the aluminum plate
• Keycaps (includes Mac & Windows keycaps)
• Adjustable-actuation-point Gateron double-rail magnetic switches
  
  

The K4 HE is compatible exclusively with the Gateron Double-Rail Magnetic Switch. It does not support other magnetic switches such as the Gateron Magnetic Jade or Gateron KS-20 Magnetic switches.

Standard Version

The Standard Version features Cherry profile double-shot shine-through PBT keycaps and aluminum frames.

Gateron Double-Rail Magnetic Switches

The K4 HE comes with pre-lubed Gateron double-rail magnetic switches for an ultra-stable and ultra-responsive typing experience with lightning-fast response time. Hall effect sensors detect keypresses without physical contact, allowing precise control and smooth actuation with 0.1 mm sensitivity.

Adjustable Actuation Point

Customize each key with precision by adjusting actuation points from 0.2 to 3.8 mm in 0.1 mm increments. Set shallow keypresses for instant actions and deeper ones for deliberate inputs to reduce accidental presses and optimize both gaming and typing performance.

Last Key Priority (LKP) & Snap Click

LKP prioritizes the last key pressed, allowing fluid directional changes in games. Snap Click ensures deeper keypresses take precedence when two keys are pressed simultaneously, perfect for precise movements like counter-strafing. Both features can be enabled via the Keychron Launcher web app.

Dynamic Rapid Trigger

Keys activate or deactivate based on travel distance, not fixed actuation points. This ensures ultra-fast response times, allowing for more precise inputs during fast-paced gaming without delay.

One Key. Multiple Actions

With Dynamic Keystrokes (DKS), assign up to 4 different actions to a single key based on press depth. Light presses can walk, deeper ones can run, and releasing can trigger additional commands—maximizing speed and control during gameplay.

Analog Mode

Analog Mode brings controller-like input to your keyboard. It allows keys to register variable input levels based on how far you press them, adding precision and fluidity in games like racing simulators and sports titles.

Keychron Launcher

Low Latency Performance

The K4 HE delivers industry-leading latency performance, outperforming flagship competitors in real-time responsiveness.

Satisfying Keyboard Acoustics

Enhanced with pre-lubed switches, 3.5 mm EVA acoustic foam, EPDM foam, and a silicone pad, the K4 HE delivers a soft, deep "thock" sound for a refined typing experience.

Includes system toggle and keycap sets for both Mac and Windows. You can save two layouts on the keyboard, one for each OS, and switch between them with ease.

Double-shot PBT Keycaps

The PBT keycaps provide excellent oil resistance, long-term durability, and a satisfying typing feel. Standard versions feature shine-through cherry profile; special editions use non-shine-through OSA profile.

Hot-swappable

Hall Effect switches can be swapped effortlessly. The K4 HE supports only double-rail magnetic switches available from Keychron.
