Our Verdict

Keychron K5 Max [K1 Max, K3 Max, etc.]

NuPhy Air75 V3

The Keychron K5 Max and the NuPhy Air75 V3 are wireless mechanical keyboards with low-profile designs. Overall, these two keyboards are very comparable in terms of features and are very well-built. The NuPhy, however, includes an optional knob and clearer backlighting and should last longer on a single charge. Its newer Gateron Low-Profile 3.0 switches also provide a full 3.5 mm of travel, which is longer than the Keychron's maximum of 3.0 mm.
