What the Ultimate Ears Wonderboom 3 offers: The Wonderboom 3 has the same compact, floating IP67 format and 14-hour battery, but it still charges over Micro-USB and has similarly limited bass.
Buy the Ultimate Ears Wonderboom 4. It ranks higher for sound quality than the Ultimate Ears Wonderboom 3 and costs less, so there is no real case for the other one.

Ultimate Ears Wonderboom 3: $72 Amazon
Pros: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery - longer than the Wonderboom 2.
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.
