Our Verdict

Keychron K4

Keychron K3 (Version 2)

The Keychron K4 and the Keychron K3 (Version 2) are two wireless mechanical keyboards. Both keyboards perform very similarly, and they come with similar switch offerings, but they have different form factors and styles. The K3 V2 is a compact 75% board with a low-profile design that offers better ergonomics. On the other hand, the K4 is a nearly full-size board with a high profile, and its backlighting is white-only.
