Logitech MX Master 4 Leak: New Features & Updates

For years, the Logitech MX Master series has been the gold standard for productivity-focused wireless mice. From graphic designers to programmers and everyday professionals, the MX Master lineup has been the go-to choice for precision, comfort, and long-lasting performance. Now, leaks suggest that the Logitech MX Master 4 may arrive soon, and it’s already generating major buzz among tech enthusiasts.

In this article, we’ll dive into the leaked updates, expected improvements, design changes, and performance upgrades that could make the MX Master 4 Logitech’s best wireless mouse yet.

Why the MX Master Series Is So Popular

The MX Master series first gained attention with its ergonomic design and versatile features. Logitech combined premium build quality with advanced tracking, customizable buttons, and seamless multi-device connectivity. Over the years, the MX Master 2S and MX Master 3 refined those elements, setting a new benchmark for productivity tools.

Key reasons the MX Master series dominates:

• Ergonomic design for all-day comfort.
• MagSpeed scrolling for ultra-fast and precise navigation.
• Cross-device workflow, allowing you to control multiple computers with one mouse.
• Customizable buttons and app-specific profiles.
• Long-lasting battery life with fast charging.

Naturally, expectations are sky-high for the MX Master 4.

MX Master 4 Leaks: What We Know So Far

While Logitech hasn’t officially announced the MX Master 4, several leaks and insider reports suggest a launch is imminent. Here are the rumored updates:

1. Refined Ergonomics and Lighter Design

The MX Master series is known for its large, hand-supportive shape. Early leaks hint that the MX Master 4 will be slightly lighter while maintaining its ergonomic grip. This could make it even more comfortable for long working hours and reduce wrist strain.

2. Upgraded MagSpeed Scroll Wheel

The MagSpeed wheel was a game-changer in the MX Master 3, offering both precision scrolling and lightning-fast free-spin. Leaks suggest Logitech may enhance this technology further with quieter operation and improved durability.

3. New Side Scroll Enhancements

The horizontal scroll wheel, useful for video editors and spreadsheet users, could receive better tactile feedback and customization options.

4. Higher DPI and Improved Sensor

The MX Master 4 is expected to feature a next-gen sensor with higher DPI (up to 8000 DPI or more). This will improve tracking accuracy on multiple surfaces, including glass.

5. USB-C Fast Charging + Longer Battery Life

Battery performance has always been strong in the MX Master lineup. Reports suggest the MX Master 4 may come with extended battery life—possibly up to 90 days per charge—and faster USB-C charging for minimal downtime.

6. Bluetooth LE and Multi-Device Switching

Expect improved Bluetooth Low Energy (LE) support for better connectivity and efficiency. Logitech may also refine the multi-device switch button, making it easier to toggle between workstations.

7. AI-Powered Customization (Rumored)

One of the most exciting rumors is potential AI-driven customization, where the MX Master 4 could automatically adjust button profiles depending on the app you’re using. For example, shortcuts in Photoshop could activate instantly when the program is launched.

Design Expectations for the MX Master 4

Logitech has always taken a sleek yet professional approach to design. The MX Master 4 will likely continue this tradition, but leaks suggest:

• More premium finishes (possibly matte black, graphite, and new metallic shades).
• Refined button placement for smoother access.
• Slimmer build while retaining the iconic thumb rest.

This means professionals can expect a mouse that looks elegant on any desk setup.

• Productivity professionals who spend hours navigating spreadsheets, documents, and apps.
• Designers and video editors who need precise control and customizable buttons.
• Programmers who benefit from ergonomic comfort and workflow automation.
• Multi-device users who switch between laptops, desktops, or tablets seamlessly.

If you’re using an older MX Master 2S or earlier, the MX Master 4 will likely feel like a massive leap forward. For MX Master 3 owners, it depends on how valuable the rumored upgrades are to your workflow.

Expected Price and Release Date

Logitech has yet to confirm an official launch date. However, industry insiders speculate the MX Master 4 could debut by late 2025 with a price point similar to the MX Master 3 at launch—around $99 to $119.

Conclusion

The Logitech MX Master 4 wireless mouse looks poised to continue the series’ legacy as the best productivity mouse on the market. With improved ergonomics, enhanced MagSpeed scrolling, upgraded sensors, longer battery life, and possible AI-driven features, it’s shaping up to be a must-have for professionals and enthusiasts alike.
