Short answer: a tie on sound quality. Both are rated 3.0/5 (#38 and #39 of 62 small speakers) at nearly the same price ($19.98 vs $19.99), so choose on features and fit.
Why pick the Dayton Audio Boost Mini: A tiny, very cheap waterproof speaker with an aux input, microSD playback, stereo pairing, and USB-C charging. Watch for: Not much bass, mids slightly boosted, highs a little rolled off.
Why pick the Monster Bluetooth Speaker: A very cheap, light waterproof travel speaker with USB-C charging, aux and microSD playback, and stereo pairing. The tradeoff: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs.
Buy the Dayton Audio Boost Mini or the Monster Bluetooth Speaker on features: they are rated the same for sound quality at close to the same price.
