Introduction
Endgame Gear is a peripherals company based in Germany. After the budget-tier XM2we, Endgame Gear finally releases the enthusiast-focused XM2w 4K. At 61 g, the weight is the same, but under the hood, the XM2w 4K is all new. PixArt’s PAW3395 sensor capable of 26,000 CPI is used, along with custom Kailh GX switches for the main buttons, which, unlike most other mechanical switches, have a top and bottom contact (SPDT, single-pole and double-throw). When actuating the switch, the click therefore can already be registered when the top contact has been disengaged, instead of having to wait until the bottom contact is closed, reducing physical latency in the process. In addition, the GX switch can also be employed as a way of providing additional hardware debouncing, preventing unintended double-clicking. Furthermore, the XM2 4K comes with a USB high-speed dongle by default, allowing polling rates of up to 4000 Hz in wireless operation. At 4000 Hz, Endgame Gear cites up to 30 hours of battery life, as the XM2w 4K has virtually all power-saving features disabled to ensure the highest possible performance. The feet are of pure PTFE, and configuration is done in a lightweight utility that does not require installation. The XM2w 4K is available in either black, white, Dark Frost, or White Frost.
