Ultimate Ears Boom 4 Blue
Score: 80/100
Tribit StormBox 2
Score: 78/100Rankings

The BOOM 4 offers 360° sound, IPX7 protection and a lightweight design with 15 hours of playtime, plus wireless charging. Its modest volume, micro-USB charging, and limited bass keep it from dominating larger party scenarios. Ideal for travelers and outdoor enthusiasts who need a portable, durable speaker.

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.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the BOOM 3 for its balanced 360-degree sound, rugged IP67 build, and impressive 13.7-hour battery life, awarding it a high portability score. However, they criticize its modest maximum volume of 86.9 dB SPL, limited bass impact, and the cumbersome micro-USB charging port, noting that it falls short for users needing high-output audio.
Everyday users love the BOOM 3's durability, waterproof reliability, and truly portable design with a handy hook, as well as the long battery life and immersive 360-degree sound in small outdoor settings. Common frustrations revolve around the speaker's limited loudness and the difficulty of plugging in the micro-USB charger.

“360-degree cylindrical design delivers balanced sound from all listening angles, creating an immersive audio experience.”

“Maximum output limited to 86.9 dB SPL, which may be insufficient for large outdoor gatherings or parties.”

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.
