Compare Keychron Q2 HE vs Q4 HE Differences Side by Side

This comparison is for buyers deciding between Keychron's two compact Hall Effect keyboards. The choice is difficult because both share premium aluminum builds, gasket mounts, and advanced magnetic switch features like adjustable actuation and rapid trigger. The decision ultimately hinges on whether you prioritize the ultra-high 8K polling rate and dedicated arrow keys of the 65% Q2 HE, or the more portable 60% form factor and true wireless versatility of the Q4 HE.
