Short answer: the Ultimate Ears Boom 3 for sound, the Wonderboom 2 for price, though neither ranks well in its class. The Boom 3 has rich and warm bass without muddying the mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity and PartyUp pairing for up to 150 speakers, and both are IP67 rated and float. But both are not stereo with barely any bass and recessed treble, and the Boom 3 costs $134.99 against the Wonderboom 2’s $80. Both are rated below 3.0/5 among the 151 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
Buy the Ultimate Ears Wonderboom 2. Both are rated the same for sound quality, and it costs $54.99 less than the Ultimate Ears Boom 3.

The Two Speakers In Full
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.
