Verdict

The Keychron K4 Max is a versatile 96% layout (100-key) wireless mechanical keyboard that features tri-mode connectivity, including 2.4 GHz wireless with a 1000 Hz polling rate, Bluetooth 5.1, and USB-C wired options. It is powered by open-source QMK firmware, allowing for extensive key remapping and macros via the Keychron Launcher web app, and includes specialized Keychron Super switches that are hot-swappable. Key pros include its multi-device pairing for up to three devices, high-quality double-shot PBT keycaps in an OSA profile, and an upgraded acoustic design with multiple layers of IXPE and EPDM foam for a superior typing sound. However, notable cons include its lack of an included wrist rest—which may be necessary due to its relatively tall front height—and the compact layout that lacks gaps between key clusters, which can make it difficult for some users to locate specific keys like the arrows or numpad zero.
