Compare Ajazz AK820 Pro vs AULA AU75 Differences Side by Side

This comparison is for buyers deciding between two similarly priced, feature-rich 75% wireless mechanical keyboards. The choice is difficult because both offer gasket mounts, triple-mode connectivity, hot-swappable sockets, and a 4000mAh battery. The Ajazz AK820 Pro introduces a customizable TFT screen and a lighter, partially aluminum build, while the AULA AU75 focuses on a deeply damped typing sound with five layers of foam and a heavier, all-ABS construction. Your preference for visual feedback versus acoustic character will be the deciding factor.

Pros and Trade-offs

Your priority dictates the choice. If you value an interactive display, a lighter build for mobility, and a spec sheet with more confirmed details like polling rate, the Ajazz AK820 Pro is the clear option. If your main goal is a deeply muted, creamy typing sound out of the box and you don't mind the extra weight, the AULA AU75's layered foam construction is its defining feature. Both are competent keyboards, but they cater to different sensory preferences.

  • −Heavier at 980g and taller at 44mm, making it slightly less portable.
  • −Case material is listed solely as ABS plastic, lacking the aluminum accent of the Ajazz.
  • −No vendor-provided details on polling rate or specific plate material.
