Short answer: the Ultimate Ears Boom 3 for sound, the Wonderboom 3 for the drop rating and price, though neither ranks well in its class. The Boom 3 offers rich and warm bass without muddying the mix, crisp highs, excellent 15-hour battery life and PartyUp pairing for up to 150 speakers, but it costs $134.99 against $85.99. The Wonderboom 3 is IP67 rated, floats and survives a 5 ft drop, though it is not stereo and has barely any bass; the Boom 3 shares those last two flaws. Both are rated below 3.0/5 among the 151 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
Buy the Ultimate Ears Wonderboom 3. Both are rated the same for sound quality, and it costs $49 less than the Ultimate Ears Boom 3.

The Two Speakers In Full
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.
