A Bold Step Forward for
Logitech’s iconic MX Master series has long been the go-to choice for professionals, creatives, and power users craving precision and ergonomics. With its fourth generation now surfacing in fresh certification filings, leaked marketing material, and EU Intellectual Property Office listings, we are getting a clearer look at what’s coming. Though Logitech has yet to announce specs or a release date, the design evolution hints at exciting changes — without abandoning the legacy that made the MX Master a household name among productivity gear.
MX Master 4: Design Tweaks & Features at a Glance
The recently surfaced EUIPO filing confirms that the MX Master 4 continues Logitech’s commitment to ergonomic excellence. From a distance, it mirrors the MX Master 3/3S in form, but subtle refinements suggest this isn’t just a minor iteration.
Most notably, there’s a third side button — a controversial addition. While it may simply be remappable, there’s speculation it could serve AI-integrated functions, sparking mixed reactions from long-time users. In addition, the side profile has been re-engineered with a sharper cutout, optimizing visibility and accessibility for the thumb button. The button itself now spans the full thumb rest area, likely increasing comfort and functionality.
Another noticeable change is the relocation of the LED battery indicator, now positioned directly below the main scroll wheel — a practical placement that keeps vital info in your line of sight. The scroll wheel itself appears slightly more elevated, and the main click buttons have been reshaped subtly to improve tactile feedback.
While Logitech hasn’t revealed performance specs, price, or materials yet, fans are hopeful that long-standing issues — like inconsistent Bluetooth connectivity and wear-prone surfaces — will finally be addressed. Given the marketing assets already created and multiple certifications logged (including Brazil’s Anatel and now the EUIPO), a full launch seems imminent.

A Deeper Look into Logitech’s Strategic Design Direction
Logitech’s approach with the MX Master 4 reveals a blend of conservatism and risk-taking — and that’s a smart move. Rather than radically changing the silhouette or overall button layout, the company is choosing to refine what already works while introducing just enough newness to spark interest. This iteration appears aimed at both pleasing existing fans and drawing in new users curious about AI-enhanced peripherals.
The addition of the third side button could be transformative. If programmable, it adds a new layer of customization. But if it’s hard-coded for AI functions (voice activation, assistant access, etc.), it may alienate users who value full control. Either way, Logitech is clearly preparing for a future where peripherals aren’t just tools, but smart assistants in their own right.
The relocation of functional elements like the battery LED and the thumb button’s redesign show that Logitech is listening to user feedback. Ergonomic tweaks, even if minor, can drastically improve long-term use and reduce fatigue — crucial for daily users who spend 8+ hours with a mouse in hand.
Moreover, positioning the scroll wheel more prominently signals Logitech’s continued emphasis on scrolling precision — a hallmark of the MX series with its MagSpeed tech. All eyes will be on whether Logitech upgrades internal components like the sensor, connectivity chips, or introduces silent clicking — something the MX Master 3S was praised for.
What’s missing so far is insight into material changes. One of the biggest criticisms of previous models has been the wear-down of the rubberized coating over time. If Logitech addresses this and enhances durability, the MX Master 4 could solidify its place as the pinnacle productivity mouse.
With AI integration growing across platforms, this model might be Logitech’s way of transitioning from mere hardware to intelligent interface solutions — a step that may define future interactions between users and digital environments.
