Compare AULA F75 vs Keychron K3 QMK V3 Differences Side by Side

This comparison is for buyers deciding between two feature-rich 75% wireless keyboards at different ends of the design spectrum. The AULA F75 offers a traditional, gasket-mounted typing experience with extensive sound dampening, while the Keychron K3 QMK V3 provides a radically thin, low-profile form factor. The decision is challenging because both support hot-swapping and wireless connectivity, but prioritize vastly different user experiences: acoustic refinement versus portability and firmware customization.

Pros and Trade-offs

Your priority dictates the choice. If you want a immersive, thocky typing experience with maximum wireless uptime and gaming features, the AULA F75 is the clear pick. If you need a keyboard for travel, value deep programmability with QMK, or strongly prefer a low-profile typing angle, the Keychron K3 QMK V3 is the superior tool. Both are competent, but they serve distinct user profiles.

AULA F75

  • +Five-layer internal sound dampening including Poron foam, IXPE switch pad, PET pad, and silicone.
  • +Large 4000mAh rechargeable battery for extended wireless use.
  • +Triple-mode connectivity with Bluetooth, 2.4GHz wireless, and wired USB.
  • +Includes a multimedia control knob and Cherry-profile double-shot PBT keycaps.
  • +Gasket mount structure for a softer, more consistent typing feel.
  • −Heavier at 1023g, making it less portable.
  • −Software is noted in reviews to have compatibility issues and is Windows-only.
  • −Lacks the deep, open-source firmware customization of QMK.
