Our Verdict
Ultimate Ears MEGABOOM 3
Marshall Emberton II
The Ultimate Ears MEGABOOM 3 is a better speaker than the Marshall Emberton II. The Ultimate Ears gets a touch louder than the Marshall, with significantly less compression at max volume, so your audio doesn't degrade as much when the volume is maxed out. It gives you more control over your speaker's sound profile thanks to the graphic EQ and presets in its companion app. It's better-built too, and the manufacturer even advertises it can float in water. That said, the Marshall can produce a more extended low-bass than the Ultimate Ears.
