Logitech MX Master 4 Debuts With Integrated Haptics and Actions Ring

Reviewers praise ergonomics alongside customizable shortcuts; haptic support remains limited at launch.

Overview

  • Logitech confirms a $119.99 price, October availability, an 8,000 DPI sensor, USB‑C charging and up to 70 days of battery life in a 150 g right‑handed design.
  • A new Haptic Sense Panel in the thumb rest delivers configurable feedback for actions and cues, with four intensity levels and Logi Options+ required to enable system and app effects.
  • The Actions Ring opens via a dedicated thumb control to surface app‑specific shortcuts, AI quick links and macros, and it can now handle device switching; plugins require an Options+ login.
  • Native haptic integrations at launch include Adobe Photoshop, Lightroom and Zoom, with Premiere Pro expected soon, and Logitech has released an SDK to broaden third‑party support.
  • Hardware tweaks include a USB‑C Logi Bolt receiver on non‑Mac models, a more durable textured top surface, ultra‑quiet clicks, larger PTFE feet and a relocated gesture button under the side wheel.
