Short answer: the Soundcore Boom Go 3i. It ranks #2 of 62 small speakers by sound quality, rated 4.4/5, at $59.98. The Dayton Audio Boost Mini ranks #38, rated 3.0/5, at $19.98, $40 cheaper, which does not close the gap in sound quality.
The Soundcore Boom Go 3i is the better-sounding, longer-running choice. A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. It is rated for 24 hours of battery against 6.5 for the Dayton Audio Boost Mini. It links with other speakers (Auracast), which the Dayton Audio Boost Mini cannot. It has an adjustable EQ, which the Dayton Audio Boost Mini lacks. 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 Dayton Audio Boost Mini is the lighter pick. A tiny, very cheap waterproof speaker with an aux input, microSD playback, stereo pairing, and USB-C charging. At 0.4 lbs (185 g) it weighs much less than the Soundcore Boom Go 3i at 0.8 lbs (380 g). It keeps a wired aux input, which the Soundcore Boom Go 3i lacks. The catch: Not much bass, mids slightly boosted, highs a little rolled off.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality, and the $40 saving on the Dayton Audio Boost Mini is not enough to make up the difference.
