Short answer: the Onn Small Rugged Speaker. It ranks #35 of 63 small speakers by sound quality, rated 3.1/5, at $14.88; the Dayton Audio Boost Mini ranks #38, rated 3.0/5, and costs $19.98, so there is little reason to consider the other one.
The Onn Small Rugged Speaker is the deeper-bass option. A very cheap, tough waterproof mini speaker with USB-C charging, an aux input, and a speakerphone mic. Its bass reaches about 66Hz before falling 10dB, against 95Hz for the Dayton Audio Boost Mini. It links with other speakers (Party Sync Mode), which the Dayton Audio Boost Mini cannot. The catch: Its 1.5-inch driver cannot create meaningful deep bass (about 66Hz at -10dB) or the clarity and scale of better small speakers.
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 noticeably less than the Onn Small Rugged Speaker at 0.6 lbs (286 g). The catch: Not much bass, mids slightly boosted, highs a little rolled off.
Buy the Onn Small Rugged Speaker. It is rated higher for sound quality than the Dayton Audio Boost Mini and costs less, which makes it the one to get unless you need something the other one does better.
