Short answer: the Klipsch Groove/Heritage Groove, if you are buying new, though neither ranks well in its class. The Ultimate Ears Wonderboom ranks higher than it (#98 vs #101 of 150 medium speakers, 2.9/5 vs 2.8/5) but is discontinued, so only consider it used; the Klipsch Groove/Heritage Groove is still sold new at $89. Both are rated below 3.0/5 among the 150 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
The case for the Ultimate Ears Wonderboom: IP67 rated and floats. Watch for: Not stereo, barely any bass, recessed treble.
The case for the Klipsch Groove/Heritage Groove: Pretty balanced sound. The catch: Not stereo.
Buy the Klipsch Groove/Heritage Groove new; the Ultimate Ears Wonderboom is no longer sold new, so it only makes sense as a used find.
If water resistance matters to you, the Ultimate Ears Wonderboom at IPX7 (brief submersion) holds up far better than the Klipsch Groove/Heritage Groove at IPX4 (Groove), none (Heritage Groove) (splashing).

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.
