Ultimate Ears WONDERBOOM 4 Blue
Score: 78/100
Ultimate Ears EVERBOOM Charcoal Black
Score: 82/100Rankings
The EVERBOOM is a rugged mid-size speaker delivering bass-heavy 360° sound, IP67 protection and up to 20 hours of playback, with handy features like NFC and a carabiner. Its weight and bass-forward tuning limit high-frequency detail and prolonged handheld use. Best for outdoor party hosts who value durability and long battery life over ultra-lightweight portability.
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the surprisingly loud 360° sound, praising the long battery life and easy pairing, while repeatedly noting weak bass, outdated micro-USB charging, and the need to buy a second unit for true stereo as common pain points.
“exceptional sound quality as "bombastic" and top-tier”
“major punch in rich, deep bass”
“highest quality bombastic sound”
Select EVERBOOM for stronger bass and longer battery life; select WONDERBOOM 4 for ultra-lightweight, pocket-size convenience.
Professional reviewers commend the EVERBOOM for its rugged IP67 build, impressive 20-hour battery, and Outdoor Boost mode that tailors sound for open-air environments. They also appreciate the intuitive controls, NFC pairing, and Party Up capability. However, they criticize the bass-forward tuning for sacrificing high-frequency clarity and note that it is not as loud or detailed as larger UE models like the MEGABOOM 4.
Everyday users consistently praise the speaker's bombastic, bass-rich sound and its durability in wet or dusty conditions. The long battery life and convenient carabiner are also highlighted as major positives. Complaints are limited but focus on the unit's weight and the requirement to use the UE app for full EQ control.
