The HyperX Pulsefire Haste 2 Wireless has a solid upper shell but keeps the 61g[3] weight and 100 hour[2] battery life of the original Pulsefire Haste Wireless. It adds dual mode wireless to switch between 2.4GHz wireless and Bluetooth connections. We’ve also included our high-performance HyperX custom components, highlighted by the HyperX 26K Sensor which detects 26,000 DPI natively and custom HyperX Switches rated for up to 100 million clicks. You’ll also enjoy superior physical control of your mouse with low-friction skates and grip tape.
