Design, Build & Comfort
The G305 keeps its iconic symmetrical egg shape—versatile for palm grips and larger hands (19–21 cm+). At 99 g, it feels stable and premium with zero creak. The receiver stores inside the battery compartment for convenience.
The Keychron M3 is lighter at 79 g with an ergonomic, right-handed shape featuring textured side grips for better hold during intense sessions. It suits claw/palm hybrid grips well (medium to large hands) and includes RGB lighting that adds flair without overwhelming.
Grip & hand-size notes: Palm grip or bigger hands → G305’s bulkier feel offers more support. Claw/fingertip or extended use → M3’s lighter weight and textured sides reduce fatigue. In humid areas (like parts of South Asia), M3’s grip pattern helps against sweat.
Sensor Performance & Gaming
G305’s HERO sensor remains accurate and consistent—no acceleration issues, great on most pads.
M3’s PixArt PAW3395 is a top-tier sensor (same as in premium mice), offering higher DPI, faster tracking (650 IPS/50G), and sharper response in fast-paced FPS like Valorant or CS2. Latency is excellent on both in wireless mode, but M3 edges out for competitive play.
Battery & Connectivity
G305 dominates with 250 hours on one AA—swap instantly, perfect for no-downtime gaming or travel without outlets.
M3 is rechargeable (USB-C, play-while-charging) with 70–140 hours (RGB off/on). Tri-mode (Bluetooth + wired) excels for switching between PC, Mac, laptop, or tablet—ideal for mixed work/gaming setups.
Buttons, Switches & Software
G305 → Logitech G HUB (mature, onboard profiles). M3 → Keychron software for DPI, polling, macros; RGB customizable. Switches feel crisp on both.
Warranty/support: Logitech’s global 2-year is easier; Keychron solid but newer.
Global tip: Check Keychron official site or local retailers for M3 bundles (often include extra receivers/adapters) at competitive prices.
Final Verdict: G305 Lightspeed vs Keychron M3 (2026)
The Keychron M3 wins for most modern gamers in 2026—lighter build, superior sensor, rechargeable convenience, and tri-mode flexibility make it feel more current while staying affordable.
But the G305 Lightspeed crushes it at $26.99—if battery swapping and proven trust are priorities, it’s still the safest, no-regrets classic.
Both outperform basic wired mice. Match to your grip and workflow—your sessions will feel smoother.
