Short answer: the Soundcore 2, narrowly. Both are compact and light, but the Soundcore runs 24+ hours from a 5200mAh cell at $29.99 while the Wonderboom 2 is IP67 rated and floats. The Ultimate Ears is not stereo, has barely any bass and recessed treble, with a slightly boosted 93Hz upper bass and a dip at 9kHz.
Buy the Soundcore 2. It is rated higher for sound quality than the Ultimate Ears Wonderboom 2 and costs less, which makes it the one to get unless you need something the other one does better.

Soundcore 2: $29.99 Amazon eBay
Newer model: the Soundcore 3, ranked higher, rated 3.4/5.
Pros: Soundcore 2 uses 2x 38mm fullrange. Its 318 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, aux input and stereo playback make it a practical option for its intended room or portable use.
Cons: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.

Ultimate Ears Wonderboom 2: $80 Amazon eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
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.
