Short answer: the Doss Soundbox XL. It ranks #53 of 77 large speakers by sound quality at $75.99; the Ultimate Ears Epicboom ranks #57 and costs $216.81, so there is not much of a tradeoff to weigh.
What the Doss Soundbox XL gets right: 32W output power, 100dB max volume, 10-hour battery life, IPX4 splashproof, MicroSD card slot, dual woofer setup with subwoofer, built-in microphone, TWS pairing support. The catch: A little hollow sounding.
On the Ultimate Ears Epicboom side: 17 hour battery with USB-C charging (first UE portable with USB-C). Set against that: Not very deep bass for the size.
Buy the Doss Soundbox XL. It ranks higher for sound quality than the Ultimate Ears Epicboom and costs less, so there is no real case for the other one.
If battery life is a priority, the Ultimate Ears Epicboom is rated for 17 hours versus 10 hours for the Doss Soundbox XL.
If water resistance matters to you, the Ultimate Ears Epicboom at IPX7 (brief submersion) holds up far better than the Doss Soundbox XL at IPX4 (splashing).
