Logitech MX Master 4 High-Performance Wireless Mouse

Logitech MX Master 4 High-Performance Wireless Mouse

The Logitech MX Master 4 is the newest flagship addition to Logitech’s MX Master line, engineered for efficiency and control. One of its standout innovations is a Haptic Sense Panel built into the thumb rest, which delivers customizable vibration feedback for actions like gesturing, using shortcuts, switching between screens or devices, or executing macros. Paired with the new Actions Ring overlay (via Logi Options+ software), users can assign frequently used tools, shortcuts, and workflows to materialize around the cursor, reducing repetitive hand movement and improving workflow speed. In terms of tracking, it uses an 8,000-DPI Darkfield high-precision sensor , allowing accurate cursor control even on challenging surfaces (including glass) and with fine control down to minimum DPI settings.The scroll wheel is a magnetic MagSpeed wheel capable of ultra-fast free-spin scrolling — up to ~1,000 lines per second — yet can snap back into ratcheted mode for precise, line-by-line scrolling. For connectivity, the mouse supports both Bluetooth Low Energy and a high-performance USB-C Bolt receiver , offering secure wireless communication and reduced latency, especially in noisy wireless environments. It can pair with up to three devices and allow switching between them easily via buttons or Actions Ring. Battery life is very strong: Logitech claims up to 70 days of use on a full charge under typical conditions. If you’re low on battery, a quick charge of just one minute can provide approximately 3 hours of further usage. Physically, it has dimensions of approximately 128.15 × 88.35 × 50.8 mm , and weighs about 150 grams . The design also features “Quiet Click” buttons (rated about 90% quieter than earlier MX Master models) for more subdued clicks, which helps in shared or open office settings. Ergonomics-wise, the sculpted shape supports long usage sessions, with side- and thumb-wheels, gesture buttons, and textured surfaces. It uses recycled materials — plastics made partly from post-consumer recycled sources, recycled cobalt in the battery, and unpainted plastic parts where feasible, as Logan strives for sustainability.
