Our Verdict

Corsair K100 AIR

ASUS ROG Falchion RX Low Profile

The ASUS ROG Falchion RX Low Profile and the Corsair K100 AIR are wireless, low-profile gaming keyboards. The ASUS has a much smaller compact (65%) form factor and has a touch bar that you can customize using the configuration software. The Corsair is a significantly larger full-size model, but it's also noticeably thinner. It offers slightly better overall gaming performance and supports a higher maximum polling rate. It also has a digital screen display, dedicated macro keys, and dedicated physical buttons for media controls.
