What will you mostly use it for?
The C3 HE's full-size layout makes it a practical pick for office work, programming, and workflows that use a numpad. The Q3 HE takes the gaming category through its higher wired polling-rate options and additional magnetic-switch functions. For modding, the Q3 HE's DIY or barebones option and aluminum construction are notable, though both remain limited to magnetic switches. Travel is a close call between two wired boards, with neither listing a carrying case.
Pick the Keychron Q3 HE
- The Q3 HE supports polling rates up to 8000 Hz in wired mode, while the C3 HE is listed at 1000 Hz.
- Both offer adjustable actuation and Rapid Trigger, and the Q3 HE also supports Dynamic Keystrokes and Analog Mode.
