Ultimate Ears WONDERBOOM 4 Blue
Score: 78/100
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 Ultimate Ears WONDERBOOM 4 provides 360° sound, IP67 waterproofing and up to 14 hours of battery life in a lightweight, floatable design. Limited bass response, micro-USB charging and lack of a companion app may disappoint audiophiles. Perfect for outdoor enthusiasts and casual listeners needing durable, portable audio.

Professional reviewers commend the WONDERBOOM 4 for its lightweight, durable design, clean sound with little compression, and useful Outdoor Boost and Podcast modes, but they criticize its limited bass, recessed treble, lack of true stereo without pairing, and modest maximum SPL for larger indoor spaces.
Everyday users love the rugged, floating build and the surprisingly loud 360° sound, praising the long battery life and easy pairing, while repeatedly noting weak bass, outdated micro-USB charging, and the need to buy a second unit for true stereo as common pain points.
“competes head-to-head with the best.”
“the one to beat”
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.
