Doss SoundBox Pro+
Score: 79/100
Soundcore Boom 3i
Score: 78/100Rankings
The DOSS SoundBox Pro+ P300 delivers a powerful 40 W stereo output with IPX6 waterproof protection and a 20-hour battery for outdoor gatherings. Its lack of advanced lighting and occasional Bluetooth range issues limit its premium appeal, and high-volume use reduces runtime. Best for users who want loud, bass-heavy sound and waterproof durability without needing extensive lighting or extra ports.
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 highlight the SoundBox Pro+ P300's impressive 40W output, strong bass for its size, minimal distortion from dual DSP, and rapid USB-C charging, while noting its moderate top-end volume and weaker low-bass depth compared with larger units.
Everyday users consistently praise the deep bass, long battery life, and IPX6 durability for outdoor use, but they frequently mention reduced runtime at high volumes, occasional Bluetooth range hiccups, and the absence of lighting or extra connectivity options.
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.
