Short answer: the Ultimate Ears Everboom. It ranks #35 of 105 large speakers by sound quality, rated 3.9/5, at $159.99. The W-King D8 ranks #57, rated 3.5/5, at $69.99, $90 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Ultimate Ears Everboom is the better-sounding, lighter option. At 2.1 lbs (949 g) it weighs much less than the W-King D8 at 5.4 lbs (2.43 kg). It links with other speakers (PartyUp up to 50 speakers), which the W-King D8 cannot. It has an adjustable EQ, which the W-King D8 lacks. The tradeoff: Careful placement and volume setting remain important for balanced sound.
What the W-King D8 does well: 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. It plays in stereo from a single unit, unlike the Ultimate Ears Everboom.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality, and the $90 saving on the W-King D8 is not enough to make up the difference.
