These sit in different size classes, so this is not a straight ranking comparison. The Soundcore Boom Go 3i ranks #2 of 62 small speakers by sound quality at $59.98; the Soundcore 2 ranks #105 of 179 medium speakers by sound quality at $29.99.
Why pick the Soundcore Boom Go 3i: A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. The catch: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic.
The case for the Soundcore 2: A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It keeps a wired aux input, which the Soundcore Boom Go 3i lacks. It plays in stereo from a single unit, unlike the Soundcore Boom Go 3i. The catch: Bass is specified only down to 70Hz, so the low end is limited.
Buy the Soundcore Boom Go 3i ($59.98) for a small speaker; the Soundcore 2 ($29.99) suits a medium speaker instead.
