Short answer: the Soundcore 2. It ranks #105 of 179 medium speakers by sound quality, rated 3.0/5, at $29.99; the Dayton Audio Boost ranks #153, rated 2.4/5, at $29.98. With prices this close, go by the sound-quality ranking rather than the cost.
The Soundcore 2 is the better-sounding, longer-running option. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 6 for the Dayton Audio Boost. At 0.7 lbs (318 g) it weighs noticeably less than the Dayton Audio Boost at 0.9 lbs (426 g). Watch for: Bass is specified only down to 70Hz, so the low end is limited.
The case for the Dayton Audio Boost: A small, cheap soda can sized waterproof speaker with stereo pairing, microSD playback and an aux input. It charges over USB-C rather than Micro USB. The tradeoff: Some midrange peaks, treble slightly rolled off.
Buy the Soundcore 2. It is rated higher for sound quality, and the $0.01 saving on the Dayton Audio Boost is not enough to make up the difference.
