Logitech MX Master 4 May Launch Soon — Here’s What We Know

Logitech is reportedly preparing to unveil the MX Master 4, the anticipated successor to its popular productivity mouse, the MX Master 3S. A recent Bluetooth certification filing in Brazil hints that the official launch could be just around the corner.

🔍 Certification Confirms Incoming Launch

According to Brazilian tech publication Tecnoblog, the new model — registered under code MR0118 — received approval from Brazil’s Anatel regulatory agency on May 9, 2025. The certification is required due to the device’s Bluetooth functionality, categorized as a low-power wireless transmitter.

✨ Subtle but Smart Design Updates

While Logitech hasn’t officially revealed the mouse, leaked images point to slight but meaningful changes. The side scroll wheel has been subtly elevated and shifted forward for better ergonomics, and the primary click buttons are now larger, taking up more space beside the familiar MagSpeed scroll wheel — likely improving usability and comfort.

🧠 Built for Productivity — and Beyond

The MX Master line has long been favored by creatives, programmers, and multitaskers for its high-end performance and versatility. Features like gesture controls, cross-device functionality, and customizable buttons make it a top-tier productivity tool. At the same time, its responsiveness and design also make it suitable for daily use and even light gaming.

⏳ Official Reveal Coming Soon?

While Logitech has yet to make a formal announcement, the combination of regulatory clearance and leaked promotional material strongly suggests that the MX Master 4 is on its way — and we may see an official debut sooner rather than later.

Keep your eye on Logitech’s channels — a next-gen upgrade to one of the best mice on the market could be just a click away.
