Short answer: the Onn Medium Party Speaker Gen 2. It ranks #45 of 75 boombox speakers by sound quality at $90; the Demerbox DB2 ranks #51 and costs $400, so there is not much of a tradeoff to weigh.
What the Onn Medium Party Speaker Gen 2 offers: Under $100 with LED lights synced to music. Simple controls, solid Bluetooth range. Mic input for karaoke/emcee. Built-in FM radio with 16 presets. Aux port. Watch for: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass. Only available in the United States and Canada.
What the Demerbox DB2 offers: 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). Built from a Pelican case - nearly indestructible and waterproof (IP67). Multi-pair up to 6 units. Doubles as power bank and waterproof container. Watch for: Bass is not as deep as better speakers. Very overpriced.
Buy the Onn Medium Party Speaker Gen 2. It ranks higher for sound quality than the Demerbox DB2 and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Demerbox DB2 is rated for 40 hours, the Onn Medium Party Speaker Gen 2 only 20 hours.
