The Logitech MX Master 4 was officially unveiled on September 30, 2025, turning the earlier “Special Edition” leak into a product fact check. The pre-launch material pointed to the mouse’s exterior design, but it could not verify the electronics, software, price, release date or packaging. Logitech’s launch information confirms a $119.99 US list price, customizable haptic feedback, the Actions Ring shortcut overlay and an 8,000 DPI sensor.
When did the MX Master 4 launch?

Regional pricing and release timing vary. Logitech lists a US price of $119.99, while its announcement gives a European price of €129.99. Logitech Japan announced a release on October 30, 2025, at ¥21,890 including tax.
What actually leaked before launch?
Secondary reporting placed a Logitech design filing with the European Union Intellectual Property Office in June 2025. Images associated with that filing provided evidence of the mouse’s exterior design direction and helped trigger coverage of a possible MX Master 4 Special Edition.
#1 Best Overall
- Logitech MX Master 3S Bluetooth Edition is a Bluetooth only mouse, and does not come with any USB receiver / adapter or charging cable
- 8K DPI Any-surface tracking: Use MX Master 3S cordless computer mouse to work on any surface - even glass (1) - with an 8000 DPI sensor with customizable sensitivity

A design filing is not a product specification sheet. The filing or leaked image could not establish the final sensor, battery, wireless hardware, software features, price, launch date or retail packaging. Any pre-launch claim about those details was a prediction until Logitech published the product information.
What Logitech confirmed at launch
Customizable haptic feedback
Logitech describes MX Master 4 as the first MX mouse with customizable haptics. Haptic feedback adds tactile responses to supported interactions, and Logitech says the intensity and behavior can be customized rather than treated as a fixed vibration effect.

Actions Ring shortcut overlay
The Actions Ring is an on-screen shortcut overlay designed to provide quick access to frequently used tools. Logitech positions it as a way to reach commands without repeatedly navigating menus. Its behavior is configured through Logi Options+.

The mouse uses a sensor adjustable from 200 to 8,000 DPI. Logitech says it tracks on glass, a useful capability for desks where a conventional optical sensor may struggle. DPI is a sensitivity setting, not a guarantee of greater precision at every value.

Scrolling, connectivity and charging
MX Master 4 retains Logitech’s MagSpeed scrolling system and supports multi-device pairing. The launch announcement also promises stronger connectivity, Bluetooth Low Energy support and USB-C quick charging. The published wireless range is up to 10 meters.
MX Master 4 specifications
| Specification | Confirmed detail |

The 70-day figure is Logitech’s maximum stated battery estimate, so actual runtime depends on usage and settings. Likewise, the 10-meter figure describes the published wireless range rather than a guaranteed distance in every room or through every obstruction.

| Shortcuts | Not established | Actions Ring software overlay configured in Logi Options+ |
| Sensor | Not established | 200–8,000 DPI, with glass tracking highlighted by Logitech |

What the MX Master 4 means for buyers
The most meaningful change is not the leaked shell but the combination of tactile feedback and software shortcuts. Users who spend much of the day in creative, office or development applications may benefit from assigning frequent actions to the Actions Ring. Those who want a conventional silent or vibration-free pointer should check the haptic controls in Logi Options+ and disable or reduce feedback if preferred.
At 150 g, the MX Master 4 remains a substantial productivity mouse rather than an ultralight model. Its rechargeable battery, multi-device pairing and 10-meter wireless range suit desk-based workflows that move between computers. The 8,000 DPI ceiling is ample for general productivity and high-resolution displays, while the ability to track on glass addresses a specific surface limitation.
Bottom line on the “Special Edition” leak
The leak was useful as an early signal that Logitech was developing a new MX Master design, but it was not proof of the final product. The confirmed MX Master 4 launched on September 30, 2025 at a US list price of $119.99, adding customizable haptics and the Actions Ring to a specification set that includes 8,000 DPI tracking, a 650 mAh battery rated for up to 70 days and USB-C charging.
