Our Verdict

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

NuPhy Nos75

The Keychron K5 Max and the NuPhy Nos75 are low-profile mechanical keyboards. The Keychron is part of a wide lineup of different-sized variants, while the Nos75 is only available as a compact 75% model. The Keychron is also a wireless model with a choice of switch types while the NuPhy is wired-only and only compatible with the Gateron N1 Nano switches it ships with. That said, it also has significantly more premium-feeling build quality and much better-typing quality overall. While both keyboards offer a high degree of hardware customization, only the NuPhy comes with a wide range of different mounting hardware so you can fine-tune your typing experience to your tastes. Unfortunately, the Nos75 is already discontinued and no longer available for purchase from NuPhy.
