BenQ S2-DW Zowie 4K Wireless Esports Gaming Mouse

The BenQ Zowie S2-DW is a wireless esports mouse engineered with competitive FPS gameplay as its sole priority. Weighing just 65g, it pairs a symmetrical body with inward-curved sides that provide a secure, agile hold during fast, multi-directional movements. The left-side curvature and back profile work together to reduce thumb angle, which BenQ's sports science research indicates supports a faster index finger click speed — a meaningful advantage in twitch-reflex scenarios. The redesigned side buttons are positioned for natural thumb access, reducing the need to shift grip to activate them.

At the core of the S2-DW's wireless performance is its 4K enhanced receiver, which communicates at a 4000Hz polling rate to deliver extremely low latency and reduce signal interference in busy wireless environments like tournament venues. The 3950 sensor offers adjustable DPI and lift-off distance, and all settings — including click response time and USB report rate — are configurable directly on the mouse without any driver installation. This driverless, plug-and-play approach means the S2-DW is ready for competition on any PC the moment it's plugged in, with no configuration files or cloud accounts required.
