Short answer: the W-King D320. It ranks #44 of 136 medium speakers by sound quality at $69.99; the Ultimate Ears Wonderboom 2 ranks #86 and costs $80, so there is not much of a tradeoff to weigh.
What the W-King D320 offers: 40W output power, IP67 waterproof, 24-hour battery life, customizable EQ app with 6 preset modes, Bluetooth 5.3, AUX and MicroSD support, dual tweeters with passive radiators, USB-C charging Watch for: Not stereo. Warm tuning. Lacking some detail. Rolled off treble
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: 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.
Buy the W-King D320. It ranks higher for sound quality than the Ultimate Ears Wonderboom 2 and costs less, so there is no real case for the other one.
There is a real battery-life gap here: the W-King D320 is rated for 24 hours, the Ultimate Ears Wonderboom 2 only 12 hours.
