Score: 84/100Rankings
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.
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the surprisingly loud 360° sound, praising the long battery life and easy pairing, while repeatedly noting weak bass, outdated micro-USB charging, and the need to buy a second unit for true stereo as common pain points.
“perfect for parties”
“floats great.”
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.
