Pros and Trade-offs

The Keychron K4 Max is the recommended choice for users who want the most features and performance from their 96% keyboard, especially for programming, gaming, and customization. However, if you are on a tighter budget or want a keyboard with a long, proven track record of user satisfaction, the K4 V2 remains a solid and reliable option. Your final decision will depend on whether the advanced firmware and 2.4 GHz connectivity of the Max justify the price premium.

Keychron K4 Max

  • +Includes a dedicated 2.4 GHz wireless connection for a more stable and responsive gaming experience.
  • +Features multiple layers of acoustic foam (IXPE, PET, EPDM) and a steel plate for an enhanced typing sound and feel.
  • +Equipped with screw-in stabilizers for more stable and less wobbly larger keys like the spacebar and shift.
  • +Comes with durable double-shot PBT keycaps in a unique OSA profile for better oil resistance and comfort.
  • −Has only one review so far, making long-term reliability less certain than the more established V2.

Keychron K4 V2

  • +Benefits from a proven design with over 490 reviews and an average rating of over 4.7 out of 5 stars.
  • +Offers a lower entry price, making it a great value for those new to mechanical keyboards or with a strict budget.
  • +Provides a choice of an aluminum frame variant for a more premium feel at a lower cost than the K4 Max.
  • +Has a dedicated Caps Lock indicator light, a small but appreciated convenience feature.
