Compare Keychron K4 Pro vs V6 Max Differences Side by Side

This comparison helps buyers decide between two wireless QMK/VIA mechanical keyboards from Keychron: the K4 Pro with a compact 96% layout and the V6 Max with a traditional full-size 100% layout. The decision is hard because both offer excellent programmability, hot-swappable switches, south-facing RGB, and strong build quality at similar price points. The key trade-off involves layout size versus wireless connectivity, as the V6 Max includes a 2.4 GHz mode for gaming while the K4 Pro relies on Bluetooth and saves desk space. Your choice ultimately depends on whether you prioritize a smaller footprint or full-size convenience with lower-latency wireless.
