Product Description

The Keychron X4 is a wired 75% mechanical keyboard designed for users who want a balance between compact layout and full functionality. It suits gamers needing low input latency and typists who prefer a flexible typing experience with customizable firmware. Its gasket mount design and high polling rate support both work and gaming environments.

Key Features

  • 1000 Hz polling rate reduces input delay, beneficial for fast-paced gaming.
  • QMK open-source firmware allows extensive key remapping, macros, and lighting customization through a web app.
  • Two keycap options: OEM profile ABS or Cherry profile PBT, both double-shot for durability and shine-through lighting.
  • Multiple red backlight modes provide visual variety without overwhelming brightness.
  • Pre-lubed Keychron mechanical switches offer a smooth and consistent typing feel out of the box.

Build Quality

  • Gasket mount with a polycarbonate plate improves typing acoustics and adds slight flex for comfort.
  • ABS plastic case with an aluminum knob combines lightweight construction with a tactile control element.
  • Adjustable typing angles (4°, 8°, 10°) and curved keycaps support ergonomic hand positioning for extended use.
  • Plate-mounted stabilizers reduce key wobble on larger keys.

Connectivity and Compatibility

  • Wired USB Type-C connection ensures stable and low-latency input.
  • Compatible with Windows, macOS, and Linux systems, supporting broad user environments.
  • Cable routing options on the case allow flexible desk setups.

Typing Experience

  • Gasket mount design softens keystroke impact, reducing finger fatigue and producing a quieter sound profile.
  • Pre-lubed switches enhance smoothness, though clicky switch lubrication is not included.
  • Keycap profile choice affects typing feel and sound; ABS keycaps may wear faster than PBT.

Trade-offs

  • No wireless connectivity, limiting portability and multi-device use.
  • Backlighting limited to red LEDs, which may not suit users wanting full RGB customization.
  • ABS plastic case may feel less sturdy compared to metal alternatives.
  • Unknown noise level compared to other gasket mount keyboards, so sound preference may vary.
