Logitech MX Master 4 Launches With Haptic Feedback and Actions Ring

Orders are live at $119.99, with initial integrations narrow and an SDK planned to expand third‑party support.

Overview

  • New thumb‑rest Haptic Sense delivers customizable tactile cues via Logi Options+, configurable across system actions and supported apps.
  • The on‑screen Actions Ring supplies radial shortcuts, including an AI launcher for ChatGPT, Perplexity, Gemini and Copilot, and can switch paired devices.
  • At launch, native haptics work in a small set of apps—Photoshop, Lightroom and Zoom—with Premiere Pro to follow, and Logitech is releasing an SDK for broader support.
  • Hardware retains the MagSpeed wheel and 8,000 DPI Darkfield tracking on glass, adds 90% quieter clicks, weighs about 150 g, and targets up to 70 days per charge with one‑minute quick top‑ups.
  • Logitech cites 2x stronger wireless thanks to a new chip, optimized antenna and a USB‑C Logi Bolt receiver; the mouse ships in early October with Mac and business variants and includes a one‑month Adobe Creative Cloud trial.
