The Endgame Gear XM2w 4k is a wireless gaming mouse with a medium-sized symmetrical shape characterized by a wide supportive rearward hump. It belongs to a wider family of Endgame Gear XM2 mice which all share the same shape. This mouse uses a PixArt PAW3395 sensor with a Nordic nRF52840 MCU, and it supports a maximum wireless polling rate of 4000Hz. It's also noteworthy for using uses Kailh GX single-pole double-throw (SPDT) switches, which offer unique performance settings and latency benefits compared to conventional mechanical switches. For more details, see the Main Button section.
Our Verdict
The Endgame Gear XM2w 4k is satisfactory for work, though it isn't designed specifically with this use in mind. That said, it has excellent all-around build quality and a comfortable, symmetrical shape with a supportive rearward hump. You can reprogram buttons using the lightweight configuration software, and it connects wirelessly with its included USB receiver. Unfortunately, its scroll wheel lacks helpful productivity features like L/R inputs and free scrolling.
Excellent build quality.
Connects wirelessly with its 2.4GHz receiver.
Software is a lightweight executable file.
Lacks productivity features such as L/R scroll will tilt inputs or free scrolling.
No Bluetooth support for multi-device pairing.
The Endgame Gear XM2w 4k is a fantastic FPS gaming mouse. It has a comfortable symmetrical shape with a supportive rearward hump, which is ideal for a claw or fingertip grip for most hand sizes. It delivers outstanding all-around sensor performance and remarkably low click latency. It's also fairly lightweight, but this depends on your frame of reference. While it's easy to move quickly and accurately, it's somewhat heavier than many recent competing models.

Popular Mouse Comparisons
The Endgame Gear XM2w 4k is a wireless gaming mouse. It's part of Endgame Gear's wider XM2 line-up of mice which all share the same medium-size symmetrical shape with a fairly wide and supportive rearward hump. This mouse is positioned as a wireless alternative to the wired Endgame Gear XM2 8k and a higher-performance alternative to the more budget-oriented Endgame Gear XM2we. Compared directly to the XM2we, it has a newer sensor, support for higher polling rates, and unique SDPT switches.
Competing in a crowded price segment, the XM2w 4k goes up against similarly shaped and slightly less expensive mice like the Scyrox V8, the Ninjutso Sora V2, or slightly smaller alternatives like the LAMZU Atlantis Mini 4K. While its relatively heavier weight and lower 4k polling rate may seem less compelling than some of its lighter 8k-capable rivals, its standout feature is its SDPT switches. These switches provide significant latency advantages over conventional mechanical or optical switches found on other gaming mice. Combined with excellent build quality and lightweight executable software, the XM2w 4k offers a unique high-performance competitive option worth considering, especially if you favor a claw grip.

The Endgame Gear XM2we is a more budget-friendly model in the same lineup as the Endgame Gear XM2w 4k. Altogether, the Endgame Gear XM2w 4k is better suited for more competitive gamers. Both are wireless mice that share the same shape, but the XM2we doesn't quite match the raw gaming performance of the XM2w 4k. The XM2w 4k has a newer sensor, supports a higher polling rate, and uses unique SPDT switches which provide exceptionally low click latency.
The Endgame Gear XM2w 4k and the Endgame Gear XM2 8k are models in the same lineup that share the same shape. Both mice are exceptionally good competitive gaming picks so choosing between them largely comes down to your preference for wireless versatility. The XM2w 4k has wireless connectivity while the XM2 8k is a wired-only model. That said, the XM2 8k also supports a higher polling rate of 8000Hz, providing slightly better and more consistent raw gaming performance.
The Endgame Gear XM2w 4k and the Scyrox V8 are wireless gaming mice with similar symmetrical shapes that have a wide rearward hump. Both provide remarkably good raw performance for competitive gaming, but the Scyrox is a better choice if you have a strong preference for lightweight mice. Comparatively, the Endgame Gear has unique SPDT switches that can achieve slightly lower and more consistent click latency. While the margin is very slight and never something you'll notice in-game, the Endgame Gear may be the better choice if you value getting the lowest possible click latency performance possible.
The Ninjutso Sora V2 and the Endgame Gear XM2w 4K are wireless gaming mice with similar symmetrical shapes and wide, supportive rearward humps. The Ninjutso is noticeably lighter and offers slightly better sensor performance, supporting a higher polling rate—though only with a separate dongle. In contrast, the XM2w 4K features unique SPDT switches with hardware debounce, delivering lower and more consistent click latency. Both mice provide top-tier raw performance for competitive gaming. While the Ninjutso has measurably better sensor latency and the XM2w 4K better click latency, the differences are imperceptible in-game. If you prefer a lighter mouse, the Ninjutso may be the better choice.
