Notice: We're proud to introduce our Test Bench 1.4 update, which adds a new Input Granularity Test to help you better compare keyboards with adjustable input settings, like those with Hall effect or optical analog switches. This update also revises how we classify keyboards based on their output type. You can read more about these changes in our changelog.

Our Verdict

Corsair K100 AIR

NuPhy Nos75

The Corsair K100 AIR and the NuPhy Nos75 are low-profile mechanical keyboards. The Corsair is a thinner, full-size, wireless model designed specifically for gaming. It has a higher maximum polling rate of up to 8000Hz over a wired connection, offering better overall raw performance. It also uses Cherry MX Ultra Low Profile Tactile switches and has extra features such as dedicated media controls and shine-through legends, which the NuPhy lacks. Comparatively, the NuPhy is a bit thicker and has a more premium solid aluminum case. It offers a better overall typing experience and uses Nano N1 switches. Unfortunately, it's been discontinued and is no longer available for purchase new.
