Design and Ergonomics

The MX Master 4 retains the signature sculpted design that supports the hand and wrist for long hours of use. It is shaped to fit the natural curve of the right hand, providing comfort and reducing strain during extended work sessions. The soft-touch finish and improved surface coating offer better grip and long-term wear resistance. The mouse includes a thumb rest and a strategically positioned thumb-wheel for easy horizontal scrolling and quick navigation.

Performance and Features

Darkfield Sensor Technology: Tracks flawlessly on virtually any surface — including glass as thin as 4 mm — making it ideal for both office and travel use.

MagSpeed Scroll Wheel: The precision-engineered steel scroll wheel automatically shifts between ratchet mode for line-by-line control and free-spin mode for fast scrolling through long documents or web pages.

Haptic Sense Panel: New to the MX Master 4, this feature provides subtle vibration feedback during specific gestures, actions, or when switching between paired devices.

Customisable Buttons: All buttons can be reassigned to different commands or macros using Logitech Options+, allowing for tailored productivity setups in creative apps, browsers, or office software.

Multi-Device Control: Supports up to three devices simultaneously, with an easy-switch button underneath to toggle between them. Logitech Flow technology enables seamless movement of cursor, text, and files across multiple computers.

Battery and Charging: The internal lithium-polymer battery provides about 70 days of use per charge, depending on usage. The mouse supports fast USB-C charging — one minute of charging can power several hours of work.

Sustainability: Built using post-consumer recycled materials, with a more energy-efficient design and eco-friendly packaging.
