Logitech MX Master 3S vs. 3: Is the Upgrade Worth It?

At a Glance: Key Similarities and Differences

Performance & Sensor Showdown

• Real-World Use: For most office and creative work, the 3’s 4,000 DPI is still more than sufficient.
• Both mice feature Darkfield tracking, working flawlessly on glass and glossy surfaces.

The Sound of Silence: Clicking Experience

• MX Master 3S: Features near-silent mechanical clicks, ideal for shared workspaces or libraries.
• MX Master 3: Has a standard, satisfyingly tactile but Audible click sound.
• Consider your environment; this is the most noticeable day-to-day difference between the two models.

• Identical connectivity options: Bluetooth Low Energy or a unified 2.4GHz USB receiver.
• Seamless multi-computer control via Logi Options+ software and Flow technology on both mice.

Verdict: Which One Should You Buy?
