Score: 84/100
Soundcore Boom 3i
Score: 78/100Rankings
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 Soundcore Boom 3i is a rugged outdoor speaker delivering 50 W output and powerful BassUp 2.0 bass, with an IP68 rating and floating design for water use. Its 830 g weight and lack of auxiliary input or power-bank functionality make it less portable and versatile. Ideal for active users who prioritize durability and bass over lightweight convenience.

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.
“perfect for parties”
“floats great.”
Editors and professional sources commend the Boom 3i for its rugged construction, IP68 waterproofing, and innovative floating capability, while emphasizing the strong bass output achieved through BassUp 2.0. The Bluetooth 5.3 connectivity and PartyCast/TWS features are also highlighted as reliable for group listening, though independent deep-dive reviews are limited.
User feedback in the available data is minimal, with no explicit pros or cons recorded. The official product description suggests users appreciate the bass performance and floatability, but there is no concrete evidence of recurring praise or complaints from everyday consumers.
