Short answer: the Onn Medium Party Speaker Gen 2. It ranks #58 of 89 boombox speakers by sound quality, rated 3.1/5, at $90; the Monster Rockin’ Roller 270 ranks #82, rated 2.1/5, and costs $249, so there is little reason to consider the other one.
What the Onn Medium Party Speaker Gen 2 does well: Under $100 with LED lights synced to music. The tradeoff: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass.
The case for the Monster Rockin’ Roller 270: 100 hour battery life. Watch for: Bass not as deep as competitors, less neutral than ION speakers.
Buy the Onn Medium Party Speaker Gen 2. It is rated higher for sound quality than the Monster Rockin’ Roller 270 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Water resistance is not close: the Onn Medium Party Speaker Gen 2 is rated at IPX7 (brief submersion), well ahead of the Monster Rockin’ Roller 270 at IPX4 (splashing).
