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 that supports 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, which allow for smoother and faster actuation with every click. The HyperX Optical Switches are designed to maintain 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 weighing 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. Additionally, with the HyperX NGENUITY software, you can monitor battery life, reassign key 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 to OMEN gaming laptops with Instant-Pair support. Experience more gaming comfort with the smoothly gliding skates and the included grip tape panels. Furthermore, the Pulsefire Haste 2 Pro is NVIDIA Reflex validated, allowing you to check the system latency between the mouse and monitor and optimize your PC's performance.
