## What reviewers say

**Marshall Emberton III** — Two whitelisted outlets (Tom's Guide, TechRadar) hands-on tested the Emberton III over several weeks. Both praise class-leading battery life (30-32 hours vs a ~20-hour category norm), the rugged Marshall-amp styling, and impressively loud, punchy sound for the small size. Both flag the same core limitation: mids get de-emphasized and the sound turns harsh with bass distortion when pushed loud, plus there is no custom EQ (only three fixed presets) and no aux input.
