Short answer: the Ultimate Ears Epicboom, since both are short on bass but it charges by USB-C, though neither ranks well in its class. It runs 17 hours on USB-C, the first UE portable with it, and costs $213.41 against the Megablast’s $240. The Megablast’s draw is Alexa integration over Wi-Fi and Bluetooth, but its bass is not very deep compared to the competition either. Both are rated below 3.0/5 among the 93 large speakers; for better sound, the Tribit Stormbox Lava ranks #3 at $100.
Buy the Ultimate Ears Epicboom. It is rated higher for sound quality and still sold new, while the Ultimate Ears Megablast is discontinued.
