What will you mostly use it for?
The K3 Max has the clearest edge for gaming and office setups that can use 2.4 GHz, and it adds listed acoustic foam and screw-in stabilizers. The K3 Pro is lighter and thinner, making it the more travel-oriented option based on the listed dimensions and weight. Programming is a close match because both include QMK, VIA, and hot-swap support. For content creation, the Pro's JIS and extra ISO choices are useful if those layouts match your typing needs.
Pick the Keychron K3 Max
- The K3 Max supports 2.4 GHz wireless, which the K3 Pro does not list.

“I sold my k3 pro and got this. The one I got drops connection intermittently or doesn't type or respond right away. It sounds nice, but stiff reds are not as pleasant to type on as previous keyboards reds. I really thought I ordered hotswap RGB max but seems…”
