The Pro Air is the first wireless mouse of ROCCAT's Kone line. It combines this series' Bionic Shell design and Titan optical switches with cable-free use, thanks to a battery that can fast-charge via USB type C. For those that prefer to stick with wires, however, it has a new Pro sibling with PhantomFlex technology and otherwise identical gaming-focused specs.
