Logitech MX Master 4: New 37-second release video leaks ahead of official launch, confirming key features
After a listing for the MX Master 4 was spotted on eBay earlier, a new release video for Logitech's upcoming mouse showed up on popular South Korean internet forum DCinside. Consequently, the 37-second video was spotted on the r/Logitech subreddit as well. In the video, features like the haptic feedback, action ring/thumb button, 8K DPI, and durable build make an appearance.
The video shows the new scroll wheel capable of "scrolling 1,000 lines per second". The video also confirms the addition of an "action ring" and extra thumb button, which were both rumored in early eBay listings and previous leaks. Durability is another focus in there, with the video briefly calling attention to a textured surface. The mouse is being marketed as "built to last" for greater longevity for heavy daily use, although the video does not specify any new warranty terms.
The updated specifications/features previously leaked online - such as the 8K DPI sensor, extra button count, and haptic feedback - appear to be accurate, as they are all reflected in the release footage. Also, the "for Mac" version seen in eBay listings and in the leaked UK product shots is also in line with the unit shown in the video.
Pricing for the MX Master 4 is will reportedly be £129 in the UK (via early eBay listings) and €129.99 as per other European leaks, which matches the price of the outgoing MX Master 3S (curr. on Amazon). Initial availability is widely expected for September 30, 2025, based on retailer timelines and previous reporting.
