Welcome to the next level. The HyperX Pulsefire Haste 2 Pro 4K opens up a whole new dimension of gaming performance. This is HyperX's first mouse to support a true polling rate of 4K without the need for additional components. This lightning-fast mouse reports its position to your PC four times per millisecond, enabling incredibly precise mouse tracking. Speaking of speed, that's not all! This mouse is equipped with HyperX Optical Switches that allow for smoother and faster actuation with every click. The HyperX Optical Switches are designed to retain the tactile feel of mechanical keys, but without input lag and debounce effect. True to its name, Haste, the Pulsefire Haste 2 Pro features a lightweight design at just 61 grams, allowing you to game for hours without the fatigue of heavier peripherals. And speaking of long gaming sessions: with the Pulsefire Haste 2 Pro, you can game for up to 90 hours on a single charge. With HyperX NGENUITY software, you can also monitor battery life, reassign important functions, and set custom DPI levels. The Pulsefire Haste 2 Pro offers versatile connectivity options, allowing you to switch between Bluetooth and 2.4 GHz at will or play and charge via USB-C. You can even forgo the dongle and connect seamlessly with OMEN gaming laptops featuring Instant-Pair support. Experience more gaming comfort with smooth gliding skates and the included grip tape panels. Additionally, the Pulsefire Haste 2 Pro is NVIDIA Reflex validated, allowing you to check system latency between your mouse and monitor and optimize your PC's performance.
