Short answer: the Ultimate Ears Wonderboom 2, though neither ranks well in its class. It ranks #111 of 175 medium speakers by sound quality, rated 2.9/5, at $80. The W-King D8 Mini ranks #135, rated 2.6/5, at $49.99, $30.01 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 175 medium speakers; for better sound, the EarFun Uboom L ranks #2 at $49.79.
The Ultimate Ears Wonderboom 2 is the lighter pick. IP67 rated and floats. At 0.9 lbs (420 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). Watch for: Not stereo, barely any bass, recessed treble.
The W-King D8 Mini is the louder, deeper-bass option. 30W output with switchable indoor/outdoor EQ modes. Its bass reaches about 63Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. Alan Ross Reviews measured it at 100dB at full volume, against 88dB for the Ultimate Ears Wonderboom 2. It is rated for 24 hours of battery against 12 for the Ultimate Ears Wonderboom 2. The tradeoff: Recessed midrange, harsh treble.
Buy the Ultimate Ears Wonderboom 2. It is rated higher for sound quality, and the $30.01 saving on the W-King D8 Mini is not enough to make up the difference.

Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5, released Jun 2024.
Older model: the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5). See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: IP67 rated and floats. Compact and light enough to toss in a bag. Measured bass extension of 82Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. Slightly boosted 93Hz upper bass Dip at 9kHz. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2019. Not technically a 360 speaker, only front and rear.
