Ultimate Ears WONDERBOOM 4 Blue
Score: 78/100
Tribit StormBox 2
Score: 78/100Rankings

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.

The Tribit StormBox Pro offers 40 W of 360° sound, IP67 protection and up to 24 hours of playback plus power-bank capability. It uses an older Bluetooth 5.0 version and lacks app control, making it slightly less future-proof. Suited for outdoor enthusiasts who value portability and durability.

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the surprisingly loud 360° sound, praising the long battery life and easy pairing, while repeatedly noting weak bass, outdated micro-USB charging, and the need to buy a second unit for true stereo as common pain points.

“fits in a backpack”

“surprising bass from small woofers”

“ideal for small mobile rigs”


Professional reviewers view the StormBox Pro as a well-balanced portable speaker that combines strong bass, 360° coverage, and rugged durability, though they wish it offered an auxiliary input and a more current Bluetooth version.
Consumers generally praise the long battery life, waterproof construction, and the convenience of the built-in power bank, while recurring concerns focus on its weight and the missing driver detail information.
