Short answer: the Ultimate Ears Wonderboom 3, though neither ranks well in its class. It ranks #110 of 175 medium speakers by sound quality, rated 2.9/5, at $79.99. The W-King D8 Mini ranks #135, rated 2.6/5, at $49.99, $30 cheaper, not enough of a saving to outweigh the sound-quality gap. 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 3 is the lighter option. IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 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.
The W-King D8 Mini is the louder, deeper-bass pick. 30W output with switchable indoor/outdoor EQ modes. Its bass reaches about 63Hz before falling 10dB, against 76Hz for the Ultimate Ears Wonderboom 3. Alan Ross Reviews measured it at 100dB at full volume, against 87dB for the Ultimate Ears Wonderboom 3. It is rated for 24 hours of battery against 14 for the Ultimate Ears Wonderboom 3. The tradeoff: Recessed midrange, harsh treble.
Buy the Ultimate Ears Wonderboom 3. It is rated higher for sound quality, and the $30 saving on the W-King D8 Mini is not enough to make up the difference.

Ultimate Ears Wonderboom 3: $79.99 Amazon $79.99 eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5, released Jun 2024.
Older models: the Ultimate Ears Wonderboom 2 (ranked lower, rated 2.9/5) and the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5). See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery: longer than the Ultimate Ears Wonderboom 2. Measured bass extension of 76Hz (-10dB).
Cons: Not stereo, barely any bass. Boosted 93Hz upper bass. Cuts bass heavily at high volume. 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 2022. Not technically a 360 speaker, only front and rear.
