Short answer: the W-King D8. It ranks #43 of 77 large speakers by sound quality at $79.98; the Ultimate Ears Epicboom ranks #57 and costs $213.41, so there is little reason to consider the other one.
What the W-King D8 offers: Decent sounding. Watch for: Slightly recessed mids. Distorted at high volumes.
What the Ultimate Ears Epicboom offers: 17 hour battery with USB-C charging (first UE portable with USB-C). IP67 rating, floats in water. Made mostly from recycled fabric and plastic. Large best-sounding UE portable that still feels portable. 180ft Bluetooth range. Watch for: Not very deep bass for the size. Gets distorted at around 70-80% with bass thuds.
Buy the W-King D8. It ranks higher for sound quality than the Ultimate Ears Epicboom and costs less, which settles it without a real tradeoff to make.
