Endgame Gear XM2w 4K: Designed for competitive use
While the external shape remains unchanged with the famous XM Claw-Grip shape, the internal structure has been optimized down to the smallest detail to achieve a low total weight of approximately 62g while maintaining a robust, hole-free housing structure.
Designed for competitive use by eSports veterans, the XM2w 4k features high-quality components including PixArt's PAW3395 sensor, Nordic nRF52840 wireless MCU, and Endgame Gear's exclusive Kailh GX SPDT switches that are GX mode compatible.

Up to 4000 Hz wireless polling frequency
For the best possible performance, the XM2w 4k is powered by a Nordic nRF52840 wireless MCU. The 4k dongle relies on a Nordic nRF52820 MCU for stable and reliable wireless data transmission, and a Nuvoton M483 MCU is used for the high-speed USB connection, which enables a wireless sample rate of up to 4,000 Hz, incredibly low providing sensor and click latency. The mouse includes the 4k dongle for optimal performance.

Industry leading click latency
The XM2w 4k sets new standards in wireless performance with an average click latency of less than 310 microseconds. With a constant polling rate of 4000 Hz for clicks, you can enjoy extremely low click latency with all sensor polling rates available. Enabling GX Speed ​​Mode reduces click latency by an additional 1.4ms, setting a new benchmark and making it by far the fastest wireless mouse in the world.
This exceptional sensitivity guarantees that every click is registered instantly, helping you in crucial moments and ensuring victory in game-changing duels.

PixArt 3395 sensor
The XM2w's 4k response time is significantly improved using the PixArt PAW3395. This sensor has a higher resolution pixel array and offers up to 26000 CPI, a lift distance of just 1mm and up to 650 IPS for maximum accuracy even in the fastest movements.
The PAW3395 also features sensor-level MotionSync for consistent and synchronized scanning. When smoothing and angle matching are disabled, the sensor tracking data is as clean as possible. All power saving features are completely disabled in "Wired Mode" to give XM2w 4k maximum performance.

Kailh GX switches, developed by Endgame Gear:
Designed for lightning-fast accuracy at all sample rates, Kailh GX mechanical switches ensure you never miss an important click. The SPDT configuration ensures optimal electrical contact and unmatched reliability. With top and bottom contacts, Kailh GX switches are simply outstanding, whether you prefer low click latency in GX Speed ​​mode or safety in GX Safe mode.
What makes them special is the crisp, distinct click feel that provides tactile feedback for better game control. Precise operation and balanced design ensure flawless, spam-friendly rapid fire.

(Almost) No energy saving measures
Designed for maximum performance from the moment you turn it on, the XM2w 4k ensures that every click and movement happens precisely and at the highest speed. While we're primarily focused on performance, we've also included customizable power management settings for those looking to extend battery life.
