What’s New in the MX Master 4

1. Haptic Feedback (Thumb Rest Area)
   The Logitech MX Master 4 adds subtle haptic feedback to provide vibration cues for battery warnings, gesture triggers, or profile switches. It’s designed to make multitasking more intuitive and tactile especially useful in silent workspaces.
   
   

2. Action Ring Menu
   Leaked and pre-release demos show a new “Action Ring” control near the thumb rest. This customizable shortcut system allows you to launch app-specific tools or commands faster great for Adobe, CAD, or video-editing professionals.
   
   

3. Refined Ergonomics
   Logitech kept the same ergonomic profile users love but added a new texture and slightly reshaped thumb area for better grip. The new materials also resist wear and feel smoother during long sessions.
   
   

4. Better Wireless Stability
   The connection speed (125Hz) stays the same, but improved antenna placement and a USB-C Logi Bolt receiver mean more consistent performance across multiple devices.

The MX Master 3S remains a powerhouse and still leads in overall value.
It offers the same precision sensor, 8,000 DPI range, silent clicks, and multi-device connectivity that professionals rely on. Unless you specifically need haptics or the new control ring, the 3S delivers 95% of the experience at a likely lower price in Bangladesh.
