For years, Logitech’s MX Master line of wireless mice has been regarded as the “best of the best” among creative professionals. They’ve struck the right balance of comfortable design, precise controls, buttery-smooth movement, solid battery life, and features galore.
Since 2022, the MX Master 3S has topped many review publications’ “Best Wireless Mouse” lists. But with Logitech introducing a new flagship MX Master mouse, you can probably expect that to change.

Logitech isn’t messing too much with what is clearly a winning formula, as the company’s new flagship, the MX Master 4, is quite similar to its predecessor, the MX Master 3S.
The two wireless mice are essentially identical, with the same ergonomic shape catered to right-handers and feature the same ultra-quiet buttons and electromagnetic scroll wheel. They also have the same 8K DPI sensor and are rated as having the same “70-day” battery life.
