The be quiet! Dark Perk Sym is a lightweight wireless gaming mouse designed for competitive play and extended sessions with minimal fatigue. It pairs a flagship PixArt PAW3950 sensor with up to 110 hours of battery life and an 8,000 Hz polling rate to deliver responsive tracking whether wireless or wired.

Why This Product

• 55g ultralight frame — Symmetrical design reduces hand fatigue during long gaming sessions and enables quick, precise flick aim across all grip styles.
• 110-hour wireless battery — Built-in rechargeable battery eliminates disposable AA cells and runs for days between charges at standard 1,000 Hz polling.
• 8,000 Hz polling rate wireless — Maintains 0.125 ms response time in both wireless and wired modes, matching wired-only competitors and removing the wireless lag penalty.
• PixArt PAW3950 sensor — 32,000 DPI flagship sensor with 50 g tracking speed and 1-2 mm lift-off distance for consistent, predictable movement across surfaces.
• Fast optical switches — Omron Optical D2FP-FN2 left and right buttons respond instantly and silently, with 5 programmable buttons total for game-specific binds.
