Compare Keychron C4 HE vs K4 Max Differences Side by Side

This comparison is for buyers weighing a traditional full-size keyboard against a space-saving 96% layout with wireless features. The decision is difficult because both keyboards are from Keychron, share similar build quality and features like hot-swap switches and QMK/VIA support, but differ fundamentally in connectivity and form factor. The C4 HE offers a unique Hall Effect magnetic switch and an extreme 8000 Hz polling rate, while the K4 Max provides 2.4 GHz and Bluetooth wireless options. Your choice will depend on whether wired performance or wireless convenience matters more to you.

Pros and Trade-offs

Select the Keychron C4 HE if your top priority is maximum wired performance and a full-size layout for gaming. Choose the Keychron K4 Max if you need wireless connectivity and a more compact footprint for a cleaner desk setup or for use across multiple devices. Both offer excellent customization and build quality, so your final choice hinges on connectivity and form factor.

Keychron C4 HE

  • +8000 Hz polling rate for ultra-low latency in wired mode.
  • +Hall Effect magnetic switches (Keychron Ultra-fast Lime) with adjustable actuation.
  • +Gasket mount design for a potentially softer typing feel.
  • +Full-size 100% layout includes a full numpad and navigation cluster.
  • −Wired-only connectivity limits desk setup flexibility.
  • −Uses a steel plate, which may be heavier and produce a firmer typing feel.
  • −Plate-mounted stabilizers might not be as stable as screw-in ones out of the box.

Keychron K4 Max

  • +Tri-mode connectivity: 2.4 GHz, Bluetooth, and wired.
  • +Compact 96% layout saves desk space while retaining a numpad.
  • +Built-in 4000mAh battery for extended wireless use.
  • +Multiple layers of acoustic foam (IXPE, PET, EPDM) for a quieter typing experience.
  • −Polling rate of 1000 Hz, which is lower than the C4 HE's 8000 Hz.
  • −PCB mount design may be less favorable for certain modifications than a gasket mount.
  • −Heavier at 1290g, making it less portable despite being smaller.
