XM2w 4k v2 - Wireless Gaming Mouse - White Frost

Introducing the XM2w 4k v2 Wireless Gaming Mouse, the upgrade to the highly anticipated high-end wireless XM series. Maintaining the iconic claw-grip shape, this powerhouse boasts an array of internal enhancements, including Endgame Gear's custom PixArt PAW3950 U+1F95A sensor and a Kailh dustproof encoder for improved reliability. Powered by the Nordic nRF52840 MCU and paired with a high polling rate dongle, this mouse delivers unparalleled wireless performance of up to 4000Hz. Experience super crisp and satisfying clicks with the custom-made, pre-sorted Kailh GX SPDT switches for the main buttons, and custom Kailh GM 2.0 for the middle and side buttons.    

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 rigors of competitive play, featuring the combination of Endgame Gear's 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 customization, 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 utilizes 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 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, you'll enjoy ultra-low click latency 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 you in crucial gaming moments and helping secure those game-winning duels. Endgame Gear didn't stop there. They've optimized motion latency 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 your gaming advantage.

Kailh GX Switches developed by Endgame Gear

Designed for lightning-fast precision at all polling rates, the mechanical Kailh GX switches guarantee you won't miss a crucial click. Their SPDT configuration ensures optimal electrical contact and unmatched reliability. Featuring both top and bottom contacts, Kailh GX Switches excel whether you prefer 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.

Prioritizing Performance

Endgame Gear engineered the wireless technology to prioritize performance over anything else. By running the sensor in permanent Corded Mode and minimal power-saving on the Nordic 58240 MCU, Endgame Gear ensures unrivaled responsiveness for your 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. Users can easily customize these settings to tailor their gaming preferences and also 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, empowering gamers with 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's possible to easily install either large or small skates with the smaller skates fitted by default. The larger area offers added flexibility when customizing 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 your skates is now quick and clean, every time.
