The Pulsefire Haste 2 Core Wireless (8R2E6AA) is HyperX's lower-cost symmetrical wireless mouse, running on a single AAA battery over a 2.4 GHz dongle or Bluetooth 5.2, with a HyperX Core sensor rated to 12,000 DPI and a 1000 Hz maximum report rate.

Specifications checked 26 Sept 2026Manufacturer specifications, not a hands-on test.
Two wireless modes from one AAA cell: HyperX rates it at up to 100 hours on 2.4 GHz and up to 200 hours on Bluetooth, and the battery is user-replaceable.
Its 124.3 × 66.8 mm body has what HyperX calls a familiar symmetrical shape from the original Pulsefire Haste 2, at a stated 70 g operating weight, with six buttons reassignable in NGENUITY.
HyperX rates it at 12,000 DPI, 300 IPS and 1000 Hz, with TTC Gold switches rated for 20 million clicks, and lists no wired mode.
NGENUITY and NVIDIA Reflex need the 2.4 GHz adapter, both side buttons are on the left, and HyperX's box list does not mention the dongle or battery.
