Compare Keychron K15 Max vs K3 Max Differences Side by Side

This comparison is for buyers choosing between two low-profile wireless 75% keyboards from Keychron: the K15 Max and the K3 Max. The decision is hard because both share core features like QMK/VIA support, a 1000 Hz polling rate, and hot-swappable low-profile switches. The main trade-off is layout ergonomics versus portability and compatibility with more standard keycap sets. The K15 Max uses an Alice layout designed for a more natural typing posture, while the K3 Max uses a standard 75% layout that may feel more familiar.
