So, you’re wondering about the Logitech MX Master 4? Let’s get straight to it: it’s a solid, high-end productivity mouse that builds on its predecessors’ strengths. If you’re coming from an MX Master 3 or 3S, you’ll find it familiar but refined, with some thoughtful improvements that make a difference in day-to-day use. If you’re new to the series, prepare for a comfortable, feature-packed experience designed for serious work.
Logitech tends to evolve the MX Master line rather than reinvent it, and the MX Master 4 follows this pattern. They’ve focused on subtle, impactful changes rather than a complete overhaul.
Design and Ergonomics: A Familiar Feel
The core shape of the MX Master 4 remains largely consistent with its predecessors. This is good news for long-time users who appreciate the sculpted, right-handed design that fits well in most palms.
The Palm Rest and Thumb Rest
The signature ergonomic shape is still there, providing excellent palm support. Your hand naturally settles into a comfortable position, reducing strain during extended use. The thumb rest is also familiar, offering a stable perch for your thumb and housing the gesture button and horizontal scroll wheel.
Button Placement and Tactility
Logitech has been refining button placement for years, and the MX Master 4 shows that experience. All buttons are within easy reach without requiring awkward stretches. The main left and right click buttons have a satisfying, albeit quiet, click. The side buttons (forward and back) are well-defined and easy to differentiate by feel.
Material Choices
The MX Master 4 uses a combination of high-quality plastics and a grippy, textured finish on the sides. It feels premium and durable in hand. Logitech has also made strides towards using more recycled plastics in their products, which is a welcome step.
MagSpeed Electromagnetic Scrolling: Still a Standout Feature
The MagSpeed scroll wheel is arguably one of the most compelling reasons to choose an MX Master mouse, and it’s back and as good as ever on the MX Master 4.
Hyper-Fast vs. Ratchet
This dual-mode scroll wheel automatically switches between a precise, clicky ratchet mode and an incredibly fast, frictionless hyper-scroll mode. It’s fantastic for navigating long documents, spreadsheets, or web pages. You can manually switch between modes with a dedicated button just behind the scroll wheel, but the automatic switching is so well-tuned that you’ll rarely need to.
Horizontal Scrolling
The dedicated horizontal scroll wheel tucked away in the thumb rest is another productivity booster. Perfect for navigating wide spreadsheets, video timelines, or large image files without resorting to keyboard shortcuts or dragging scroll bars. It feels smooth and precise.
Sensor Performance: Precision Where It Counts
A productivity mouse needs to be accurate and reliable, and the MX Master 4 doesn’t disappoint in this regard.
Darkfield Tracking
Like its predecessors, the MX Master 4 uses Logitech’s Darkfield high-precision sensor. This means it can track on virtually any surface, including glass (at least 4mm thick). This flexibility is a huge advantage for users who might work in various environments or on unconventional desk surfaces.
DPI Range and Customization
The DPI (dots per inch) range is adjustable from 200 to 8000 DPI, with increments of 50 DPI. This provides ample customization for different screen resolutions and user preferences. You can adjust this through the Logi Options+ software. While 8000 DPI might seem like overkill for productivity, it offers fine-tuning for multi-monitor setups or high-resolution displays.

Connectivity and Power: Reliable and Convenient
Logitech has honed its connectivity options over the years, making the MX Master 4 a versatile tool for various setups.
Multi-Device Connectivity (Flow)
One of the standout features of the MX Master series is its ability to connect to up to three devices simultaneously.
Easy-Switch Button
A button on the underside of the mouse allows you to quickly switch between connected devices. This is invaluable if you’re working across multiple computers, say a desktop and a laptop, or even different operating systems.
Logitech Flow
Even better is Logitech Flow, a software feature that allows you to seamlessly move your mouse cursor (and even copy-paste text, images, and files) between up to three computers just by moving your cursor to the edge of the screen, as if they were a single, extended desktop. It truly streamlines workflow across multi-computer setups and is a big time-saver once you get used to it.
Wireless Technology
The MX Master 4 offers two primary wireless connection methods.
Logi Bolt Receiver
The mouse comes with a Logi Bolt USB receiver. This provides a secure and robust connection, especially in busy office environments where other wireless signals might cause interference. It’s also often preferred for enterprise environments due to its security protocols.
Bluetooth Low Energy
Alternatively, you can connect via Bluetooth Low Energy (BLE). This is convenient for laptops without available USB ports or when you want to minimize the number of dongles you carry. The Bluetooth connection is generally stable, though some users might find the Logi Bolt connection slightly more responsive in specific scenarios.
Battery Life and Charging
Battery life is another area where the MX Master series typically excels, and the MX Master 4 is no different.
Long-Lasting Power
Logitech claims up to 70 days on a full charge, which is impressive and, in my experience, quite accurate for typical usage. This means you’re not constantly thinking about recharging your mouse. A full charge takes about two hours.
USB-C Fast Charging
When you do need to charge, the MX Master 4 uses a USB-C port located at the front of the mouse. A quick 1-minute charge can give you around 3 hours of use, which is incredibly handy if you find yourself low on power in the middle of a workday. You can also use the mouse while it’s charging.
Software Customization: Logi Options+
The MX Master 4 truly shines when paired with Logitech’s Logi Options+ software. This is where you unlock its full potential.
Button Reassignment
Almost every button on the MX Master 4 can be reassigned to perform a different function. This includes the main left and right clicks, the two side buttons, the horizontal scroll wheel clicks (if available), and the gesture button.
Application-Specific Customizations
A key feature is the ability to set application-specific profiles. For example, the side buttons could be “undo” and “redo” in Photoshop, but “next track” and “previous track” in your media player. This level of customization makes the mouse incredibly versatile and tailored to your specific workflows.
Gesture Button Functionality
The gesture button, located within the thumb rest, is a powerful tool. By default, holding it down and moving the mouse up, down, left, or right performs different actions (e.g., show desktop, switch applications).
Customizing Gestures
You can fully customize these gestures in Logi Options+. You could assign them to media controls, specific shortcuts, or even custom macros. Once you integrate gestures into your workflow, you’ll wonder how you ever managed without them.
Pointer Speed and Scrolling Adjustment
Logi Options+ provides fine-grained control over pointer speed (DPI) and scrolling behavior.
Smooth Scrolling
You can enable “smooth scrolling,” which makes scrolling feel more fluid and less jerky, especially for long documents. This is a subtle but noticeable improvement for some users.
Scroll Wheel Force
While not as granular as some gaming mice, you can also adjust the force required for the MagSpeed wheel to switch between ratchet and hyper-fast modes, though the automatic detection is usually spot-on.
Who Is It For?
The Logitech MX Master 4 isn’t a budget mouse, and it’s not trying to be. It’s a premium productivity tool designed for a specific user base.
The Power User
If your work involves long hours at the computer, navigating complex software, or multitasking across multiple devices, the MX Master 4 is tailor-made for you. Its ergonomic design, advanced scrolling, and deep customization options significantly enhance efficiency.
Developers, Designers, and Editors
Professionals in fields like software development, graphic design, video editing, or data analysis will find the MX Master 4 incredibly useful. The horizontal scroll wheel, application-specific button assignments, and precise tracking are genuinely beneficial for these tasks.
Multi-Device Setups
Anyone who regularly switches between two or three computers will appreciate the seamless connectivity of Logitech Flow and the multi-device pairing. It removes a minor but persistent friction point in a cross-device workflow.
Not for Everyone
It’s important to note who it might not be for:
- Gamers: While accurate, it’s not a gaming mouse. Its weight, ergonomic shape (less ideal for claw or fingertip grips common in gaming), and lack of ultra-high polling rates mean it’s not optimized for competitive gaming.
- Minimalists: If you prefer a small, lightweight mouse with minimal features, the MX Master 4’s size and complexity might be overkill.
- Budget-Conscious Buyers: This is a premium product with a premium price tag. If your budget is tight, there are other capable mice available, though they might lack some of the MX Master 4’s unique features.
