Verdict

The Keychron K4 Pro is a 96% layout wireless mechanical keyboard featuring QMK/VIA support for extensive key remapping and macro programming. It boasts a hot-swappable PCB, south-facing RGB LEDs, and double-shot PBT keycaps, delivering a premium typing experience with pre-lubed internal foam and silicone pads for sound dampening. While it offers versatile Bluetooth 5.1 and USB-C connectivity compatible with Mac and Windows, its main drawbacks include a high-profile frame that may require a wrist rest for comfort and the lack of a 2.4GHz wireless dongle for lower-latency gaming.
