Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. Both are rated 2.9/5 for sound quality (#95 and #96 of 150 medium speakers), and the Ultimate Ears Wonderboom 4 costs $59.99 against $85.99 for the Ultimate Ears Wonderboom 3, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 150 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
What the Ultimate Ears Wonderboom 4 does well: It charges over USB-C rather than Micro USB. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Ultimate Ears Wonderboom 3 does well: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. Watch for: Not stereo, barely any bass.

Ultimate Ears Wonderboom 3: $85.99 Amazon eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
Pros: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery: longer than the 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.
