Our Verdict

Keychron K8 Pro [K2 Pro, K3 Pro, K4 Pro, etc.]

Keychron S Series

The Keychron K8 Pro [K2 Pro, K3 Pro, K4 Pro, etc.] and the Keychron S Series are mechanical, hot-swappable keyboards available in a range of sizes and configurations. The K Pro series keyboards include high- and low-profile options and are all wireless models with mixed metal and plastic bodies. On the other hand, the S Series are low-profile, wired-only models with all-aluminum bodies.
