Logitech MX Master 4 Leak suggests Imminent Mouse Launch
Logitech’s MX Master 4, the anticipated follow-up to the MX Master 3S, may soon be available. Recent activity, including a Bluetooth certification in Brazil and a teaser on Instagram, suggests a launch is close.
The MX Master 4, model number MR0118, received approval from Anatel, Brazil’s telecom regulator, on May 9. This certification, required for devices with Bluetooth connectivity, categorizes the mouse as a “restricted radiation transceiver.”

While certification documents lacked images, a promotional image briefly appeared on Logitech’s instagram feed. The image, quickly removed, showed subtle design tweaks. The side scroll wheel appears slightly higher, and the primary click buttons seem larger.
The MX line is popular among creative professionals and coders, prized for its customization, gesture controls, and multi-device pairing. These features also make it suitable for casual use and light gaming.
With certification complete and marketing materials prepared, Logitech is expected to announce the MX Master 4 soon.
What’s next
Industry observers anticipate an official declaration from Logitech in the coming weeks, detailing the MX Master 4’s features, pricing, and availability.
