Short answer: the Ultimate Ears Epicboom, because it gets USB-C and a cleaner midrange, though neither ranks well in its class. The Epicboom runs 17 hours on USB-C, the first UE portable to do so, though its bass is not very deep for the size. The LG Xboom XG7 lasts an impressive 24 hours, the longer of the two, but the body flags a peaky midrange and rolled off treble. 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 the LG Xboom XG7 is discontinued, so it is only available used.
