1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsShort answer: Buy the Logitech MX Master 4 if you will use its haptic thumb-rest control and Actions Ring shortcuts. Buy the MX Master 3S if you want a proven productivity-mouse layout, documented Quiet Clicks, and a lower price. Logitech’s US store listed the MX Master 4 at $119.99 and the MX Master 3S at $89.99 on October 13, 2026, a $30 difference that can change with promotions, stock, region, and time.
The MX Master 4 is an evolution rather than a completely different class of mouse. Both are wireless productivity mice with 8,000 DPI tracking and Logitech customization software. The practical buying decision is whether the MX Master 4’s new controls will save enough repeated movement to justify its premium. An MX Master 3S owner should upgrade only when those controls solve a real workflow problem.

MX Master 4 vs. MX Master 3S: the decision at a glance
| Choose this model | Best fit | Why |
|---|---|---|
| Logitech MX Master 4 | Shortcut-heavy desktop work | It adds haptic feedback at the thumb rest and the Actions Ring software overlay for quick access to favorite tools. |
| Logitech MX Master 3S | Quiet, familiar productivity use | It keeps the established MX Master layout, offers Quiet Clicks, and was listed $30 lower on Logitech’s US store at the observed date. |
The MX Master 4’s headline additions are interaction features, not a dramatic sensor-resolution change. Logitech lists 8,000 DPI tracking for the new model, while the MX Master 3S also uses an 8,000 DPI optical sensor. If your work consists mainly of pointing, scrolling, clicking and occasional shortcuts, the 3S already covers the core use case. If you repeatedly reach for commands, switch tools or trigger custom actions, the 4 has a stronger reason to exist.
What the MX Master 4 adds
Haptic feedback at the thumb rest
The MX Master 4 introduces a haptic control in the thumb-rest area. Instead of relying only on a physical button press, the mouse can provide tactile feedback as you interact with the control. Logitech describes the haptics as a way to make interactions feel more immediate, but the usefulness depends on which actions you assign and whether tactile confirmation helps you work faster.
#1 Best Overall
- Precision you can feel with the Haptic Sense Panel; customizable (1) haptic feedback on specific actions, shortcuts, notifications enhancing productivity on this wireless Bluetooth mouse
- Effortlessly access favorite tools with Actions Ring (2) on this MX Series mouse—a dynamic, customizable overlay adapts to each app, placing most used filters, adjustments, and shortcuts at your cursor
- Scroll 1,000 lines per second and stop on a pixel with the MagSpeed scroll wheel—Logitech’s fastest (3), quietest, and most precise (4) scrolling experience
- Enjoy 2X more powerful connectivity (7) with a USB-C dongle, advanced radio chip, and optimized antenna for faster, stronger, reliable performance—or use Bluetooth for more versatility
- Ergonomic mouse designed for comfort, MX Master 4 keeps you in flow with a natural tilt, intuitive buttons, and a thumb scroll wheel that reduces hand stress for fluid navigation
This is not a claim that every click becomes quieter, faster or more accurate. Logitech’s product material emphasizes the haptic interaction; it does not establish a comparative noise measurement against the MX Master 3S. Treat haptics as a workflow feature rather than as a general performance upgrade.
Actions Ring overlay
Actions Ring is a software overlay that gives quick access to favorite tools and shortcuts. The intended benefit is reducing the distance your pointer travels to reach commands that would otherwise require a toolbar, menu or keyboard combination. You decide which shortcuts appear, so its value rises with the number of repetitive commands in your daily work.
For example, a designer could place frequently used tool commands in the ring, while a spreadsheet user might assign recurring navigation or formatting actions. Those are examples of how to configure a shortcut workflow, not guaranteed default actions. The right setup depends on the applications and commands you use.
Logitech’s 63% movement claim, properly qualified
Logitech says Actions Ring can produce “up to 63% fewer repetitive mouse movements.” That figure comes from Logitech’s 2025 Ergo Lab study of 37 MX Master mouse users performing eight desktop actions. Logitech also says results vary according to the shortcuts assigned. It is therefore a manufacturer-reported, task-specific result—not an independently replicated productivity guarantee and not a promise that every user will save 63% of movement.
Shape and surface changes
A secondary comparison identifies the MX Master 4 as the successor to the MX Master 3S and describes shape refinements, an added gesture button, and hard textured plastic replacing the 3S’s soft-touch rubber coating. These are physical-design differences that may affect how the mouse feels in your hand, but they should not be confused with independently measured comfort or durability results. No hands-on testing is established here.

Why the MX Master 3S still makes sense
Quiet Clicks are its clearest documented advantage
Logitech specifically calls out Quiet Clicks on the MX Master 3S. If you work beside other people, share a room, record audio near your desk or simply dislike sharp click sounds, this feature is a concrete reason to choose the older model. The MX Master 4’s available product description emphasizes haptics rather than providing a directly comparable click-noise specification, so do not assume the two mice sound the same.
The established customization system remains capable
The MX Master 3S works with Logitech Options+, where Logitech describes button customization, tracking-speed adjustment, app-specific customizations, Smart Actions and Flow across devices and operating systems. This means the 3S is not a basic mouse that becomes obsolete when the MX Master 4 arrives. You can still tailor controls to individual applications and build a productivity setup around the existing layout.

Logitech lists an 8,000 DPI optical sensor for the MX Master 3S and says it can track on glass with a minimum glass thickness of 4 mm. That qualification matters: “tracks on glass” does not mean every glass surface or any thickness. The MX Master 4 is also listed with 8,000 DPI tracking and support for surfaces including glass, but the material available here does not provide an equivalent minimum-glass-thickness figure for it.
The lower observed price
At the observed Logitech US store prices, the MX Master 3S cost $89.99 and the MX Master 4 cost $119.99. The $30 difference is not permanent; prices, discounts and inventory change. Still, the 3S offers a straightforward value proposition when you do not need haptic controls or an Actions Ring workflow.

MX Master 4 specifications supplied by Logitech
| Specification | MX Master 4 |
|---|---|
| Dimensions | 128.15 × 88.35 × 50.8 mm |
| Weight | 150 g |
| Tracking resolution | 200–8,000 DPI |
| Connection | Bluetooth Low Energy |
| Battery | Rechargeable 650 mAh battery |
| Battery life | Up to 70 days, according to Logitech |
| Wireless range | 10 m |
| Report rate | 125 Hz |
“Up to 70 days” is a rated figure, not a guarantee for every user. Actual endurance depends on settings, connection conditions, usage patterns and other factors. The same caution applies to the listed wireless range and report rate: they describe the manufacturer’s specification rather than an independent laboratory result.
MX Master 3S specifications and features established here
- 8,000 DPI optical sensor.
- Tracking on glass with a minimum glass thickness of 4 mm, according to Logitech.
- Quiet Clicks.
- Customization through Logitech Options+, including button assignments, tracking speed, app-specific settings, Smart Actions and Flow.
The available product information does not establish a directly comparable MX Master 3S weight, battery-capacity figure, battery-life rating, report rate or wireless-range number. Do not infer those values from the MX Master 4 specification table.
How the two mice differ in everyday work
For writing, browsing and general office tasks
Both models provide the high-resolution tracking and multi-button productivity design expected from the MX Master line. If most of your day involves documents, web pages, email, file management and occasional application switching, the MX Master 3S is usually the rational purchase when its lower observed price and Quiet Clicks match your priorities.
The MX Master 4 becomes more compelling when you can name several actions you perform repeatedly and want them available through the Actions Ring. Without a shortcut plan, the new overlay is an additional control to learn rather than an automatic productivity gain.
For application-specific workflows
Both mice can be customized through Logitech software, but the MX Master 4 adds a dedicated interaction layer. A useful test is to list the commands you repeat dozens of times per day. If those commands are already comfortable on the keyboard or existing mouse buttons, the 4 may not save meaningful time. If you frequently move to distant interface controls, an Actions Ring assignment could reduce pointer travel.

- Quiet, focused work: Quiet Click technology reduces click noise by 90%(3), creating one less distraction so you and your work neighbors can focus on work
For shared or quiet workspaces
The MX Master 3S has the documented advantage because Logitech explicitly markets Quiet Clicks. Choose it when acoustic discretion is a primary requirement. The available MX Master 4 information does not provide a matching click-noise claim, so avoid buying the 4 on the assumption that it has the same acoustic behavior.
For glass desks
The MX Master 3S is the safer documented choice when your desk surface is glass because Logitech specifies a minimum glass thickness of 4 mm for its glass-tracking claim. The MX Master 4 is also described as tracking on surfaces including glass, but an equivalent thickness qualification is not established here. Surface cleanliness, tinting and coatings can still affect real-world tracking.
Who should buy the MX Master 4?
- You want haptic confirmation. The thumb-rest haptic control is the defining physical interaction change.
- You have recurring commands to put in an overlay. Actions Ring is designed for quick access to favorite tools and shortcuts.
- You are buying new. Paying the observed $30 premium is easier to justify when you do not already own a suitable MX Master mouse.
- You accept software-dependent benefits. The value depends on configuring shortcuts and using Logitech’s customization software.
Before purchasing, write down the shortcuts you expect to use. If you cannot identify a practical set of actions, the MX Master 4’s main differentiators may remain unused.
Who should buy the MX Master 3S?
- You prioritize Quiet Clicks. This is the model’s clearly documented acoustic feature.
- You want lower cost. Logitech’s US listing was $89.99 on October 13, 2026, subject to change.
- You need reliable glass tracking. Logitech specifies glass tracking down to a minimum thickness of 4 mm.
- You already use app-specific customization. Options+ provides button remapping, tracking-speed controls, Smart Actions and Flow without requiring the MX Master 4.
- You prefer a familiar layout. The 3S is the established design, while the 4 introduces new controls and physical refinements.
Should an MX Master 3S owner upgrade?
For an existing 3S owner, this is a workflow decision rather than a specification race. Your current mouse already has 8,000 DPI tracking, Quiet Clicks and broad software customization. Replacing it makes sense when the MX Master 4 solves a specific problem that the 3S cannot solve conveniently.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Upgrade when these statements are true
- You repeatedly move the pointer across large interfaces to reach commands.
- You have tested or planned a useful set of Actions Ring shortcuts.
- Haptic confirmation would make your frequent controls easier to recognize.
- You are comfortable giving up the certainty of the 3S’s documented Quiet Click emphasis.
- The current MX Master 4 price fits your budget after checking live availability.
Keep the MX Master 3S when these statements are true
- Quiet operation is more important than new interaction features.
- Your existing button assignments and app-specific profiles already work well.
- You mainly perform ordinary pointing, scrolling and clicking.
- You cannot identify repetitive movements that an Actions Ring shortcut would remove.
- You are replacing a mouse primarily because of price, not capability.
Do not upgrade solely because the MX Master 4 is newer. The documented changes are concentrated in haptics, shortcut access, a gesture control and physical refinements; they do not establish a radically higher tracking resolution or an independently measured productivity improvement.
Best Value

Setting up the customization features
Both models rely on Logitech’s customization software for their productivity features. The exact available options can depend on the mouse model, operating system and software version, so verify current compatibility before buying.
- Install the current Logitech Options+ application from Logitech’s official support or product page.
- Connect the mouse using its supported wireless method and confirm that the application recognizes the model.
- Select the mouse in Options+ and review the available button and gesture assignments.
- Create application-specific settings if you use different commands in different programs.
- On the MX Master 4, configure the Actions Ring with shortcuts you use often enough to justify a dedicated overlay.
- Test each assignment in the application where you intend to use it, then revise shortcuts that conflict with existing commands.
Because Actions Ring is software-dependent, check current operating-system support and feature availability for your region and device before purchase. The presence of Options+ on one platform does not by itself prove that every feature behaves identically on every operating system.
Price, availability and ownership value
The only prices established for this comparison are Logitech US store listings observed on October 13, 2026: $119.99 for MX Master 4 and $89.99 for MX Master 3S. These are time-sensitive observations, not guaranteed offers. Check the live listing for your country, model variant, stock status, shipping and any current discount.
The price gap should be judged against how often you will use the MX Master 4’s new controls. A $30 premium is relatively easy to defend for someone who uses Actions Ring throughout the workday. It is harder to defend for someone who wants a quiet, customizable mouse and will leave the overlay unused.
Important limitations when comparing the models
- No hands-on testing is established for this comparison.
- Logitech’s 63% movement figure is from its own 2025 Ergo Lab study, involving 37 users and eight desktop actions; outcomes vary with assigned shortcuts.
- MX Master 4 battery life, weight, range, report rate and DPI are manufacturer specifications.
- The available information does not provide a complete, equivalent numeric specification set for the MX Master 3S.
- Prices and inventory can change after the observed October 13, 2026 listing.
- Detailed independent test data for some physical differences is not fully available in the cited secondary comparison.
Final recommendation
For most first-time buyers who want the lowest sensible cost and quiet clicks, choose the Logitech MX Master 3S. It retains the core productivity features, supports Logitech’s customization tools, tracks at 8,000 DPI and has a documented glass-tracking qualification.
Choose the Logitech MX Master 4 when haptic feedback and Actions Ring shortcuts address a real, repeated part of your work. Its $119.99 observed US price buys a new interaction model, not merely a higher sensor number. Existing MX Master 3S owners should upgrade only after identifying the specific repetitive actions the new controls will improve.
