Features
XM2w 4k V2 Wireless Gaming Mouse

Built for Competitive Play
Pioneering the essence of the renowned XM claw grip shape, the inner workings of the XM2 underwent meticulous redesign to achieve a weight of ~62g, all while upholding a robust hole-free shell design. The XM2w 4k v2 is the brainchild of esports veterans, meticulously tailored for the rigours of competitive play, featuring the combination of a custom PixArt PAW3950 U+1F95A sensor, the Nordic nRF52840 wireless MCU, and Endgame Gear's exclusive Kailh GX SPDT switches with GX Mode compatibility. For effortless customisation, the mouse is bolstered by a nimble 2.3MB configuration tool that necessitates no installation and can be executed directly from a USB stick – an ideal companion for LAN events, tournaments, or setup on the fly.

Wireless Polling Rate of up to 4000Hz
To achieve the best performance possible, XM2w 4k v2 is powered by the Nordic nRF52840 wireless MCU. The 4k dongle utilises a Nordic nRF52820 to guarantee stable and reliable wireless data transmissions. Additionally, a Nuvoton M483 MCU is used in the dongle for the high-speed USB connection, enabling high wireless polling rates of up to 4000Hz for incredibly low sensor and click latency. The 4k dongle is included with the mouse for ideal performance straight out of the box.

Industry-Leading Click Latency
The XM2w 4k v2 raises the bar for wireless performance, boasting click latency averaging below 310 microseconds.* With a steady 4000Hz polling rate for the clicks, ultra-low click latency is achieved across all sensor polling rate options. GX Speed Mode further lowers click latency by about 1ms. This exceptional responsiveness guarantees instant registration of every click, empowering players in crucial gaming moments and helping secure game-winning duels. Motion latency is optimised to an average of under 400 microseconds**, ensuring unmatched responsiveness. Initial motion latency from a standstill remains consistently fast across all polling rate options, reinforcing the gaming advantage.

PixArt 3950 Sensor
Unlock ultimate precision and lightning-fast response with the custom PixArt PAW3950 U+1F95A sensor in the XM2w 4k v2. With up to 30,000 CPI max resolution, 750 IPS, and 50G acceleration, every movement is captured with raw accuracy and maximum impact. Fine-tune the setup with 11 Lift-Off-Distance steps from 0.7 to 1.7mm, and precise 10-point CPI adjustments below 10,000 CPI for complete control. No smoothing, no angle-snapping – just pure, uncompromised performance. Motion-Sync delivers consistently timed reports at polling rates up to 4000Hz, sharpening muscle memory and perfecting competitive gameplay.
Now also available: optional locked sensor frame rate at 20,500fps for even more responsive and precise tracking performance. Furthermore, for grip styles where the mouse is not held straight to the direction of movement, the "Sensor Angle Tuning" feature allows the tracking axis to be adjusted from -127 to +127 degrees in 1-degree increments, facilitating swift swipes and opponent tracking.*
*requires firmware 1.02 or above.

Kailh GX Switches developed by Endgame Gear
Designed for lightning-fast precision at all polling rates, the mechanical Kailh GX switches guarantee no crucial click is missed. Their SPDT configuration ensures optimal electrical contact and unmatched reliability. Featuring both top and bottom contacts, Kailh GX Switches excel whether prioritising low click latency in GX Speed Mode or security in GX Safe Mode. What sets them apart is their crisp, defined click sensation, offering tactile feedback for enhanced gaming control. Precise actuation and a balanced design ensure flawless, spam-friendly rapid-fire actions.
Prioritising Performance
Wireless technology has been engineered to prioritise performance over anything else. By running the sensor in permanent Corded Mode and minimal power-saving on the Nordic 58240 MCU, unrivalled responsiveness is ensured for the gaming experience. To balance the demands of high performance and extended battery life, by default the sensor switches to power-saving mode after 1 minute of inactivity, transitioning into Deep Sleep mode after 3 minutes. These settings can be easily customised to suit gaming preferences, including disabling Power Saving and Deep Sleep altogether. With the default settings, the XM2w 4k v2 delivers approximately 30 hours of battery life for continuous gaming at a 4000Hz polling rate, allowing uninterrupted playtime at peak performance. With the new 1000Hz Power Saving mode, battery runtime for continuous gaming is extended to 54 hours.
Hybrid Skate Design
The XM2w 4k v2 comes with two sets of PTFE skates (large & small) and a sensor skate. Thanks to a hybrid design bottom shell, it is possible to easily install either large or small skates, with the smaller skates fitted by default. The larger area offers added flexibility when customising the XM2w 4k v2's glide and re-using already purchased skates. The sensor skate is optional but recommended on softer surfaces. Thanks to an improved adhesive of the v2 models, removing the skates is now quick and clean, every time.
