Logitech’s MX Master series has long been the gold standard for high-end productivity mice, blending ergonomic design with a powerful feature set. With each new version, Logitech refines the formula. While the mice generally share the same iconic, sculpted shape, the differences under the hood—from scroll wheel technology to silent clicks and haptic feedback—are significant.
Here is the updated article on the evolution of the Logitech MX Master series, now including the MX Master 2S and noting the production status of the Master 3.
The Master’s Evolution: MX Master 2S vs. 3 vs. 3S vs. 4
Logitech’s MX Master series has long been the gold standard for high-end productivity mice, blending ergonomic design with a powerful feature set. With each new version, Logitech refines the formula. While the mice generally share the same iconic, sculpted shape, the differences under the hood—from scroll wheel technology to silent clicks and haptic feedback—are significant.
Here’s a breakdown of how the series has evolved.
⚙️ The Predecessor: Logitech MX Master 2S
Launched in 2017, the MX Master 2S was the mouse that solidified the series’ reputation for productivity. It introduced Logitech Flow, a software feature that allowed a single mouse to control multiple computers, seamlessly moving the cursor (and clipboard) from one screen to another.
- Key Features: It featured a 4,000 DPI Darkfield sensor, which could track on glass. Its main scroll wheel was “speed-adaptive,” mechanically shifting from a precise ratchet to a free-spin mode when flicked hard. It used a Micro-USB charging port and came with the Unifying Receiver. Its thumb buttons were a distinctive “rocker” switch, and its clicks were tactile and audible.
👑 The Revolution: Logitech MX Master 3
The MX Master 3, launched in 2019, was a revolutionary step up, primarily due to its MagSpeed Electromagnetic scroll wheel. This new technology replaced the mechanical system of the 2S. It allowed the wheel to be precise enough for line-by-line “ratchet” scrolling, yet able to switch automatically to a near-silent, free-spinning mode that could coast through 1,000 lines in a second. The ergonomics were also refined, with a new thumb wheel and better-placed, distinct back/forward buttons.
- Key Features: It introduced the MagSpeed wheel, used a modern USB-C port for charging, and kept the 4,000 DPI sensor. It used standard, “clicky” switches.
- Current Status: The MX Master 3 is no longer in production by Logitech. While it was a groundbreaking mouse, it has been replaced by the 3S. It may be difficult to find new, and is most often found on the secondhand market.
🤫 The Silent Upgrade: Logitech MX Master 3S
The MX Master 3S, released in 2022, looked physically identical to the 3 but addressed two key pieces of user feedback: noise and precision.
- Quiet Clicks: This was the headline feature. The 3S introduced “Quiet Clicks,” which provided the same satisfying tactile feel as the original but with 90% less click noise. This made it an instant favorite for quiet offices and home workers.
- 8K DPI Sensor: The sensor resolution was doubled from 4,000 to 8,000 DPI. This was a major benefit for users with high-resolution displays (like 4K or 5K monitors) or multi-monitor setups, as it allows the cursor to cover more screen real estate with less physical hand-movement.
- Logi Bolt Receiver: It also transitioned from the older Unifying Receiver to the more secure and modern Logi Bolt USB receiver.
✨ The Haptic Innovator: Logitech MX Master 4
The MX Master 4, launched in late 2025, is the most significant leap since the original’s MagSpeed wheel. It keeps the best of the 3S (Quiet Clicks and 8K DPI sensor) and adds a new layer of tactile interaction and refinement.
- Haptic Feedback: The MagSpeed wheel now features haptic feedback. This adds a subtle, precise vibration to the wheel, offering a more tactile and controlled feel in ratchet mode and providing nuanced feedback within applications.
- New Software & Controls: It introduces the “Actions Ring,” a new software feature that, combined with a redesigned gesture button, provides a faster, more intuitive way to access shortcuts.
- Design & Connectivity Refinements: Critically, it now includes a USB-C Logi Bolt receiver, finally matching the charging port on the mouse and future-proofing its dongle for modern laptops.
Comparison at a Glance
Here is a quick table summarizing the key differences between the four models.
| Feature | Logitech MX Master 2S | Logitech MX Master 3 | Logitech MX Master 3S | Logitech MX Master 4 |
| Launch Date | June 2017 | September 2019 | June 2022 | September 2025 |

| Sensor | 4,000 DPI Darkfield | 4,000 DPI Darkfield | 8,000 DPI Darkfield | 8,000 DPI Darkfield |
| Main Clicks | Standard (“Clicky”) | Standard (“Clicky”) | Quiet Clicks (90% quieter) | Quiet Clicks |
| Scroll Wheel | Speed-Adaptive (Mechanical) | MagSpeed (Electromagnetic) | MagSpeed | MagSpeed with Haptic Feedback |
| Charging Port | Micro-USB | USB-C | USB-C | USB-C |
| USB Receiver | Unifying Receiver (USB-A) | Unifying Receiver (USB-A) | Logi Bolt (USB-A) | Logi Bolt (USB-C) |
A Note on “For Business” (B2B) Models
You will often see “For Business” versions of the MX Master 3S and 4. As you noted, these are essentially the same core product, but with key differences aimed at enterprise and IT deployment:
- Packaging: They come in simple, plain boxes (often brown cardboard) designed for mass deployment, not for retail shelves.
- Warranty: While the standard warranty is typically the same (2 years), the “For Business” models are eligible for purchasing extended warranties, allowing companies to cover their assets for up to 5 years.
- Security & Management: This is the biggest difference. Business models are designed for the Logi Bolt receiver and can be set to a “Secured Connections Only” mode that is FIPS (Federal Information Processing Standards) compliant. They also support Logitech Sync, allowing IT departments to remotely monitor and manage the devices across the company.
- Receiver: This was a key differentiator for the MX Master 3. The consumer model came with the Unifying Receiver, while the Business model came with the more secure Logi Bolt receiver. For the 3S and 4, both versions now use Logi Bolt.
For an individual user, the consumer version is perfectly fine. The “For Business” models are specifically for organizations that need enhanced security and mass-management capabilities.
Which One Should You Buy?
- Logitech MX Master 4: This is the one to get if you are a power user who wants the absolute latest technology. The haptic wheel, USB-C dongle, and refined software features make it the new productivity king.
- Logitech MX Master 3S: This is the best value for most people. You get the two most important modern upgrades—the 8K sensor and Quiet Clicks—for less money than the 4. It’s the sweet spot for nearly all users.
- Logitech MX Master 2S: If you are on a tight budget and find this mouse on a deep discount, it is still a capable productivity tool. Be aware that you’ll be using older technology, including a Micro-USB port and a louder, mechanical scroll wheel.
- Logitech MX Master 3: As it’s discontinued, it’s hard to recommend hunting one down unless you find it significantly cheaper than the 3S and you prefer audible clicks. The 3S is a direct and superior replacement.
