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.
