Short answer: the Ultimate Ears Epicboom, though neither ranks well in its class. It ranks #76 of 97 large speakers by sound quality (rated 2.9/5) at $213.41 and is still sold new; the Soundcore Trance ranks #92 (rated 2.1/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 97 large speakers, so if sound quality matters, consider the Tribit Stormbox Lava instead, ranked #3 at $100.
The Ultimate Ears Epicboom is the better-sounding, deeper-bass choice. 17 hour battery with USB-C charging (first UE portable with USB-C). Its bass reaches about 55Hz before falling 10dB, against 63Hz for the Soundcore Trance. At 4.3 lbs (1.97 kg) it weighs much less than the Soundcore Trance at 7.7 lbs (3.5 kg). The catch: Not very deep bass for the size.
The case for the Soundcore Trance: 80W power with up to 105dB output and BassUp technology. It has an adjustable EQ, which the Ultimate Ears Epicboom lacks. Watch for: Hugely recessed midrange and treble.
Buy the Ultimate Ears Epicboom. It is rated higher for sound quality and still sold new, while the Soundcore Trance is discontinued.
