The Logitech MX Master 3S is one of the finest mice to have ever slid across our desks, earning a rare five-star rating and Editors’ Choice award for its perfectly sculpted design, impressive battery life, and versatility. Logitech has done it again, improving on an otherwise perfect mouse with the MX Master 4 ($119). The latest Master mouse makes a striking first impression with new features, including haptic feedback, a gesture button, and an Action Ring digital overlay, which streamlines workflows with app-specific shortcuts. Coupled with a swath of smart revisions and design enhancements, you’ll quickly see why the Master MX 4 is a cut above all other computer mice, earning another elusive 5-star rating and an Editors’ Choice award for Best Mouse for Work.
Smoother Design With Even Softer Clicks
Let's start with the Logitech MX Master 4's design. The 4 cuts back on the rubber-textured grip that enveloped the 3S, limiting it to the right flank and the wing of the mouse, which houses the new Actions Ring button (more on that below). The rubber grips are perfectly aligned with my thumb, ring, and pinky finger (apologies to left-handed users, who've been left out again). The left and right clickers now loop around the scroll wheel to offer more area for your pointer and middle finger. It measures at 5.0 by 3.4 by 2 inches (HWD) and weighs 5.2 ounces, slightly bigger than the Master 3S’s 4.9 by 3.3 by 2 inches (HWD) and 5 ounces. (For a more in-depth look at the pros and cons of both mice, take a look at our detailed comparison.)
The MagSpeed scroll wheels placed at both the top and left side of the mouse make their return, though the left wheel is no longer tucked into the mouse. The buttons on the left flank protrude further now, making it easier to find and access with your thumb. A small button on top of the mouse switches the scroll wheel mode between a fast, unfettered scroll and a more controlled, textured scroll.

The Master 4’s sensor remains unchanged, still providing smooth and accurate tracking on virtually any surface, with a maximum DPI of 8,000.
Connectivity has also been improved, as Logitech has repositioned the internal antenna and boosted performance with a new high-performance chip. Logitech promises twice the connective strength as the previous mouse, but since I've never had an issue connecting to any device with my 3S, I’ll have to take their word for it.
What I can confirm is the improved clicks of the Master 4. The Master 3S wasn't loud by any stretch, but the Master 4 is somehow even quieter—90% quieter, according to Logitech. Clicking them side by side, the difference is immediately apparent, but rest assured, the hushed sound doesn't dampen the Master’s satisfying clicks.
Same, familiar color scheme
The mouse will come in Graphite, Pale Grey, and Black color schemes, while the dedicated Mac version will be offered in two exclusive colors: Space Black and White Silver. Each purchase includes a one-month complimentary membership to Adobe Creative Cloud. Like the Signature Slim Solar+ K980, there’s also an MX Master 4 for Business variant that offers compatibility with Logi Tune and Logitech Sync, two Logitech platforms designed to help IT teams monitor, manage, and optimize Logitech devices.
A Master at Work: New Features and Tricks
Facelift aside, one of the biggest changes to the mouse is the addition of haptic feedback. The Master 4 introduces haptic feedback into basically every function on the mouse, whether that’s simple scrolling and selecting, or more advanced video editing and design work.
There are four intensity options to choose from: subtle, low, medium, and high. I mostly stuck to medium and felt that the vibration was fairly strong. While Logitech doesn’t specify how this affects battery life, a warning in Logi Options+ notes that stronger vibrations consume more battery power. On a full charge, you can expect the mouse to offer at least 70 hours of use.
With that said, you can deploy a battery-saving mode or shut off haptics entirely. To do so, you'll still have to navigate to Logi Options +, as there’s no way to do it on the device itself.

This is the gesture button, which adds a range of functions you can access. For example, pressing the gesture button and sliding the mouse down will quickly hide or show your desktop, while holding the button and sliding the mouse up will open the start menu.

The final major change is the Actions Ring. Located in the wing of the mouse, pressing on the Actions Ring button will launch a digital overlay of eight options. Once open, just move the mouse toward the option you want and select it.
At a glance, this is a handy shortcut menu, but I was impressed by how dynamic the ring was. For example, one of the default options, Explore AI, will then open up four AI options to try out, in the same way you’d open a subfolder in your files. You can even map your volume setting to the shortcut menu, making it easy to adjust the volume using the Actions Ring.
(Credit: Joseph Maldonado)Probably the most useful addition to the productivity powerhouse is the addition of plug-ins. These plug-ins tailor the mouse shortcuts and haptics to the open application. The downside is that at this moment, there aren’t many pre-made plug-ins to choose from: Just Adobe Premiere, Zoom, and Microsoft Excel. However, there are a growing number of plug-ins in the Logi Marketplace, which include apps such as Figma, Discord, and even Microsoft Flight Simulator 2020 and 2024.
In use, the mouse functions as you’d expect. It feels extremely similar to the 3S, but is much smoother all around. The optimized button placements are a change you wouldn’t expect to notice, but it doesn’t take long for it to feel second nature. The sensor might be exactly the same as the 3S, but the widened PTFE feet made every move feel more graceful. I don’t use CAD workflows in my day-to-day, but I wish I did, because these functions work so well.
Who Doesn't Want More Options?
While the mouse is a capable driver on its own, to use the mouse to its fullest potential, you’ll have to download Logi Options+. However, you’ll be in good hands, as the utility is one of our favorites. Logi Options+ is where you’ll customize shortcuts and functions across your mouse buttons and build profiles for individual apps.
(Credit: Logitech)Mainstays like Logitech Smart Actions, a macro maker meant to automate common and complicated tasks, can be applied to the mouse, as well as Logitech’s AI Prompt Builder, which helps you craft AI-generated messages with specific parameters (called recipes). You can’t assign either of these options to your Action Ring, though.
Rounding out the Master 4’s features is the Easy Switch, which allows you to jump between three different devices with a press of a button, and Logi Flow, which allows you to transfer files, images, and text between two computers by simply dragging your mouse from one machine to the other. The Master 4 also comes with a USB-C Logitech Bolt, which can connect to up to two Logitech devices at one time. Minor gripes: The mouse does not include any storage for the USB dongle, nor does it come with a USB-C cord.
(Credit: Logitech)The MX Master 4 is compatible with a wide range of operating systems, including Windows 11, macOS 13 or later, Linux, ChromeOS, iPadOS 15 or later, and Android 12 or later. If you're still holding onto Windows 10 (like I am), you won't be able to connect your mouse via Bluetooth, but you can still use the Logitech Bolt to connect.
Action Ring aside, most of these features are not new or exclusive to the Logitech Master MX 4, but they certainly sweeten the deal. Logitech has packed this mouse full of functionality, and it’s an improvement on the already stellar 3S. But is it enough to upgrade? You might first have to ask yourself if you’re the right audience for this mouse.
If CAD workflows, spreadsheets, and maximizing your productivity are things you’re passionate about, then the Master 4 is the optimal choice, with only mice like the Razer Pro Click V2 coming within striking distance of the Master 4’s greatness. It’s hard to improve on perfection, but the Master 4 finds a way forward.
