On first glance, MX Master 3 and 3S look nearly identical same ergonomic shell, same multi-device support, same MagSpeed scroll wheel. But under the hood, 3S refines key pain points: higher sensor precision, quieter clicks, and modern updates in connectivity. If you want dependable performance today plus a bit of future readiness, 3S is the sharper bet.
Let’s make long story short: If you want the quieter clicks, greater precision, and future-proof connectivity, go with MX Master 3S. If you already own a 3 and it works fine, the upgrades are nice but not game-changing for everyone.
Why Do I Recommend the MX Master 3S?
- Quieter Clicks: Up to 90% quieter compared to 3, ideal for meetings, shared spaces, late‑night work.
- Higher DPI Sensor: 8,000 DPI “Track‑on‑Glass” sensor (vs lower in 3) means smoother, more precise tracking—even on glass surfaces.
- Same Comfortable Design + Features: You don’t lose the ergonomics, multi-device switching (Bluetooth + Logi Bolt), flow control, thumb wheel, etc.
- Better Future‑Proofing: 3S aligns better with newer connectivity (Bolt) and tracking standards.
- Minimal Trade‑offs: The upgrade is clean — you keep everything good about the 3, with fewer compromises.
