Short answer: a tie on sound quality. Both are rated 3.0/5 (#30 and #31 of 47 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: Quite light for the performance. Watch for: Not much bass, mids slightly boosted, highs a little rolled off.
Why pick the Monster Bluetooth Speaker: A very light, IPX7-rated mini speaker with USB-C charging, aux and microSD playback, speakerphone support and TWS 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.

Monster Bluetooth Speaker: $19.99 Amazon eBay
Pros: A very light, IPX7-rated mini speaker with USB-C charging, aux and microSD playback, speakerphone support and TWS pairing. It is a convenient rugged travel speaker when water resistance and small size matter more than bass. Measured bass extension of 95Hz (-10dB).
Cons: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs. It cannot deliver the scale, detail or battery endurance of stronger small-speaker rivals, and no app or EQ is available to improve the tuning.
