Imagine slipping your hand into a perfectly molded cradle – that’s the experience users rave about with Logitech's MX Master mouse. While the MX Master lineup has always been impressive, the MX Master 3 has attained almost legendary status, with some users stubbornly holding on to their aging models even as they literally fall apart. But hold on tight, because Logitech is poised to reveal the much-anticipated MX Master 4!

Recently, renowned leaker Evan Blass teased a glimpse of the MX Master 4 on X, revealing a design that closely resembles its predecessors, the MX Master 3 and 3S. One exciting detail was a soothing mint green accent around the thumb groove, although Blass noted this was likely just a placeholder and may not appear on the final version. It’s unfortunate, as this could have provided a refreshing design twist.

The excitement around this upcoming release isn't just speculation. Logitech hinted at the launch in its back-to-school campaigns, and earlier this year, Brazilian tech site Tecnoblog reported on Bluetooth certification documents for the MX Master 4. Users on Reddit have shared early sneak peeks from Logitech’s Instagram, affirming the leaked design, which appears to stick with the reliable seven-button setup, complete with metallic top and side scrolling capabilities.

For die-hard fans of the MX Master 3, the question remains: why bother upgrading? The changes are minimal, primarily beneficial to dedicated users. For instance, the side-to-side scroll wheel has been repositioned closer to the buttons, resembling a bird's beak, while the thumb rest could feature a new texture aimed at improving durability. As long as it retains that beloved metal scroll wheel and the satisfying click, it will remain the mouse of choice in any bustling white-collar workspace.

Notably, the MX Master 3S upped the ante by enhancing the resolution sensitivity from 4,000 to a remarkable 8,000 DPI, crucial for precision. While primarily designed for productivity, some enthusiastic users take the MX series into the gaming realm. However, a glaring limitation is the polling rate, capped at 125Hz, meaning how often the mouse updates its position on-screen.

In contrast, elite gaming mice like the $170 Razer Deathadder V4 Pro can achieve an astounding 8,000Hz polling rate – a level even the most ardent gamer might struggle to discern. Meanwhile, top-tier productivity mice like Razer’s Pro Click V2 boast rates up to 1,000Hz. If Logitech can push the MX Master 4 to match or exceed these specs, it may well empower users with greater flexibility in their mouse usage!
