The Endgame Gear XM2 8k is a wired gaming mouse that continues Endgame Gear's XM lineup. It shares the same shape as the wireless Endgame Gear XM2we and the previous generation Endgame Gear XM1r but brings significant performance changes. New key features include a flagship class PixArt 3395 sensor and support for an 8000Hz maximum polling rate. Additionally, this mouse uses Kailh GX SPDT (single pole double-throw) switches which offer unique performance settings compared to conventional mechanical switches. For more details, see the Main Button section below.
Our Verdict
The Endgame Gear XM2 8k performs adequately for work, though it's not specifically designed for this purpose. It boasts excellent build quality and a comfortable, symmetrical shape, and its buttons can be reprogrammed via the configuration software. However, as a wired-only model, it lacks multi-device pairing, and its scroll wheel lacks helpful productivity features like L/R inputs and free scrolling.
Amazing build quality.
Wired only, no multi-device pairing.
Scroll wheel lacks L/R tilt inputs and a free-scrolling mode.
The Endgame Gear XM2 8k is a remarkably good FPS gaming mouse. It has amazing build quality and is extremely lightweight, making it easy to move quickly and accurately. It also has incredibly low click latency and sensor latency, providing an exceptionally responsive and consistent in-game experience.

The Endgame Gear XM2 8k and the Endgame Gear OP1 8k v2 are both high-end wired mice that deliver outstanding raw performance and use Kailh GX switches with a unique single-pole double-throw design that offers lower latency than standard mechanical switches. The main difference between them is shape: the XM2 is slightly larger and wider, with a fuller back end that provides more palm support, while the OP1 8k v2 is smaller and narrower with a more centered hump. The OP1 8k v2 also supports hot-swappable switch packs sold separately by Endgame Gear, whereas the XM2 8k does not.

On the other hand, the XM2 8k is a bit larger with a broader backside designed to provide support for your palm.
The Endgame Gear XM2w 4k and the Endgame Gear XM2 8k are models in the same lineup that share the same shape.
