Short answer: the W-King D8. It ranks #57 of 105 large speakers by sound quality, rated 3.5/5, at $69.99; the Ultimate Ears Epicboom ranks #83, rated 2.9/5, and costs $228.59, so there is little reason to consider the other one.
The W-King D8 is the better-sounding, deeper-bass option. Claimed 24 hours (manufacturer specified) battery life, ipx7 protection, up to 101db and stereo playback make its feature set practical for its intended room or portable use. Its bass reaches about 49Hz before falling 10dB, against 55Hz for the Ultimate Ears Epicboom. It is rated for 24 hours of battery against 17 for the Ultimate Ears Epicboom.
Why pick the Ultimate Ears Epicboom: 17 hour battery with USB-C charging (first UE portable with USB-C). The catch: Not very deep bass for the size.
Buy the W-King D8. It is rated higher for sound quality than the Ultimate Ears Epicboom and costs less, so only choose the other one for a particular feature it does better.
