Short answer: the Klipsch Groove for a more balanced sound, the Wonderboom 2 for the water, though neither ranks well in its class. The Groove/Heritage Groove is described as pretty balanced, though it is not stereo, at $89 against the Wonderboom 2’s $80. The Wonderboom 2 is IP67 rated and floats, but it is not stereo, has barely any bass and recessed treble. 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. It is rated higher for sound quality than the Klipsch Groove/Heritage Groove and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
There is a real gap in water resistance: the Ultimate Ears Wonderboom 2 at IP67 (brief submersion) against the Klipsch Groove/Heritage Groove, which has IPX4 (Groove), none (Heritage Groove) (splashing).

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.

Klipsch Groove/Heritage Groove: $89.00 Amazon eBay
Pros: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life.
Cons: Not stereo. Bass doesn’t go as deep as others its size. Gets distorted at higher levels. Wouldn’t generally recommend these old speakers as they can’t compete with modern speakers for bass performance and features.
