Verdict

The Keychron K4 Pro is a versatile 96% layout (100-key) wireless mechanical keyboard featuring full QMK/VIA support for extensive key remapping and macro customization. It offers flexible connectivity via Bluetooth 5.1 for up to three devices or a 1000Hz polling rate USB-C wired connection, powered by a substantial 4000 mAh battery that provides up to 300 hours of use with backlighting off. Key characteristics include a hot-swappable PCB compatible with 3-pin and 5-pin MX switches, south-facing RGB LEDs for better visibility, and a refined internal build featuring sound-absorbing foam and a silicone dampening pad for a 'thocky' typing experience. Main pros include its space-saving yet functional design with a dedicated number pad, high-quality double-shot PBT keycaps in the OSA profile, and seamless compatibility with macOS, Windows, and Linux. Notable cons include its significant height (up to 40mm) which often requires a wrist rest for ergonomic comfort, and a lower 90Hz polling rate in wireless mode which may not suit competitive gaming.
