The HyperX Pulsefire Haste 2 Pro 4K is a 61 g wireless gaming mouse in Slate Grey, built for fast shooters. Its 4K wireless receiver polls at up to 4000 Hz over 2.4 GHz, the HyperX 26K sensor reaches 26,000 DPI and 650 IPS, and the main buttons use HyperX optical switches. HyperX rates the battery at up to 90 hours at 1 kHz, or up to 30 hours at the full 4 kHz, and it also connects over Bluetooth or a USB-C cable.

What 4000Hz Polling Means on the HyperX Pulsefire Haste 2 Pro
Polling rate is how often the mouse reports its position to the computer. A typical wireless gaming mouse reports 1000 times a second; the HyperX Pulsefire Haste 2 Pro reports up to 4000 times a second through its included 4K wireless receiver. Each report arrives 0.25 ms after the last instead of 1 ms, so cursor movement is sampled more finely on high-refresh monitors.
You only get 4000 Hz on the 2.4 GHz receiver. Wired over the USB-C cable the mouse runs at 1000 Hz, and over Bluetooth at 125 Hz. HyperX also lists the mouse as NVIDIA Reflex validated, and it pairs instantly with select OMEN gaming laptops.
HyperX 26K Sensor
The sensor is the HyperX 26K, with up to 26,000 DPI, 650 IPS tracking speed and 50 G acceleration. Out of the box you get four DPI presets, 400, 800, 1600 and 3200, and you can change them in HyperX NGENUITY software. Most FPS players sit between 400 and 1600 DPI, so the headroom above that is for very high-resolution screens or players who like tiny hand movements.
61g Shape, Switches and Skates
At 61 g, the HyperX Pulsefire Haste 2 Pro is light enough for fast flicks without feeling fragile. HyperX describes a symmetrical shape, measuring 124.3 mm long, 66.8 mm wide and 38.2 mm high, and includes grip tape in the box so you can add texture to the sides and buttons.
The left and right buttons use HyperX optical switches, which register a click with light rather than a metal contact, so there is no debounce delay to wait for. There are six buttons in total, low-friction skates on the base, RGB lighting, and one onboard memory profile for your settings.
Battery: 90 Hours or 30 Hours
HyperX gives two battery figures, and they depend on polling. Both are measured in 2.4 GHz mode with continuous use and the RGB lighting switched off, so leaving the lighting on shortens them. At 1 kHz the HyperX Pulsefire Haste 2 Pro lasts up to 90 hours. At the full 4 kHz it lasts up to 30 hours. The battery is rechargeable Li-ion polymer and charges over USB-C, and you can keep playing while it charges.
The detachable HyperFlex 2 cable is USB-C to USB-A and 1.8 m (5.9 ft) long, and an extension adapter is included so you can bring the wireless receiver closer to the mouse on a large desk.
Slate Grey Finish and Compatibility
This listing is the Slate Grey version, the colour HyperX lists for this model. Grey is a middle ground: it shows less dust than black and fewer marks than white, and it suits both dark and light desk setups.
HyperX lists compatibility with PC, PS5 and Xbox Series X|S. Custom DPI, lighting and button mapping are set in HyperX NGENUITY on a PC.
Who This Is Not For
If you want 4000 Hz all day without frequent charging, be realistic: HyperX quotes up to 30 hours at 4 kHz, so a heavy player may charge it twice a week. Bluetooth is limited to 125 Hz, which suits office work, not gaming.
There is only one onboard profile, so players who switch between several saved setups on different PCs will need NGENUITY. And if you prefer a larger, heavier ergonomic mouse with a thumb rest, a 61 g symmetrical shape will feel small.
