Compare Keychron K15 Pro vs K3 Max Differences Side by Side

This comparison is for buyers who want a low-profile mechanical keyboard but are torn between two different ergonomic approaches. Both are 75% wireless boards from Keychron with QMK/VIA support, low-profile PBT keycaps, and 1000 Hz wired polling. The decision is hard because the K15 Pro offers a distinctive Alice layout and a programmable knob, while the K3 Max provides a 2.4 GHz wireless mode and interior acoustic foam. Unless you specifically want an Alice layout, the K3 Max is the more versatile and conventional choice.
