Short answer: the W-King D20. It ranks #29 of 75 boombox speakers by sound quality at $193; the Demerbox DB2 ranks #51 and costs $400, so there is little reason to consider the other one.
What the W-King D20 offers: Comes with 2 wireless microphones Watch for: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks
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 W-King D20. It ranks higher for sound quality than the Demerbox DB2 and costs less, so there is no real case for the other one.
