Our Verdict

Corsair K100 AIR

Keychron S Series

The Corsair K100 AIR and the Keychron S Series keyboards are low-profile mechanical keyboards. The Corsair is a wireless model designed specifically for gaming. It has lower latency and a higher maximum polling rate of 8000Hz. On the other hand, the Keychron S Series keyboards are wired-only models for more general use. They also feature hot-swappable PCBs and are available in stock red, brown, or blue switch types, while the Corsair is only available with a tactile switch type.
