Short answer: the Ultimate Ears Wonderboom 4, if you are buying new, though neither ranks well in its class. The Ultimate Ears Wonderboom ranks higher than the W-King D8 Mini (#112 vs #135 of 175 medium speakers) but is discontinued; its replacement, the Ultimate Ears Wonderboom 4, is rated 2.9/5 at $74.50 and is still sold new. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Wonderboom is the lighter choice. IP67 rated and floats. At 0.9 lbs (425 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). The catch: Not stereo, barely any bass, recessed treble.
The W-King D8 Mini is the longer-running option. 30W output with switchable indoor/outdoor EQ modes. It is rated for 24 hours of battery against 10 for the Ultimate Ears Wonderboom. It keeps a wired aux input, which the Ultimate Ears Wonderboom lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. The catch: Recessed midrange, harsh treble.
Buy the Ultimate Ears Wonderboom 4, the replacement for the discontinued Ultimate Ears Wonderboom; it is rated higher for sound quality than the W-King D8 Mini.
