Ultimate Ears MEGABOOM 4 Blue
Score: 84/100
Marshall Emberton III
Score: 87/100Rankings
The Marshall Emberton III combines 360° True Stereophonic sound, IP67 durability and over 32 hours of battery life in a compact, vintage-styled design. Its limited EQ presets and lack of deep sub-bass keep it from matching larger powerhouses. Suited for users who value balanced sound, ruggedness and long endurance in a stylish package.
The MEGABOOM 4 is a rugged cylindrical speaker delivering 360° sound and thundering bass with a 20-hour battery and IPX7 waterproofing. Its bulkier weight, lack of USB-C charging, and occasional dropouts limit ultra-portable use. Best suited for party hosts and outdoor enthusiasts who prioritize volume and durability.

Professional reviewers commend the MEGABOOM for its richer bass, balanced treble, and robust IPX7 waterproofing, noting its superior 360° sound dispersion and long battery life. However, they also criticize its bulkier, heavier form factor and the lack of modern USB-C charging or built-in EQ controls, which limit its portability and fine-tuning capabilities.
Everyday users rave about the thundering bass, all-day battery life, and the speaker's ability to float and survive drops, making it a party favorite. Recurring complaints focus on the weight, occasional Bluetooth dropouts at long range, and the absence of an app-based EQ for sound customization.
“perfect for parties”

“competes head-to-head with the best.”
Professional reviewers consider the Emberton III a top-small Bluetooth speaker, lauding its 32+ hour battery, authentic Marshall tone, and phenomenal 360° audio while noting the limited EQ presets and lack of smart features as the main drawbacks. They view it as a stylish, rugged option that outperforms many rivals in sound balance and endurance, though not a mandatory upgrade for owners of the previous Emberton.
Everyday users overwhelmingly praise the Emberton III for its rich, clear sound, impressive bass for its size, premium build quality, and marathon-long battery life, often saying it competes head-to-head with higher-priced options. The most common complaints revolve around the restricted EQ presets and a bass response that isn't as deep as larger speakers.
