Short answer: the Klipsch Groove, if you are buying new, though neither ranks well in its class. The Ultimate Ears Wonderboom ranks higher than it (#102 vs #105 of 157 medium speakers, 2.9/5 vs 2.8/5) but is discontinued, so only consider it used; the Klipsch Groove is still sold new at $9. Both are rated below 3.0/5 among the 157 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
The Ultimate Ears Wonderboom is the lighter, tougher option. IP67 rated and floats. At 0.9 lbs (425 g) it weighs much less than the Klipsch Groove at 1.7 lbs (770 g). It is rated IPX7 against IPX4 for the Klipsch Groove. Watch for: Not stereo, barely any bass, recessed treble.
What the Klipsch Groove does well: Pretty balanced sound in a compact, splash-resistant form factor. It keeps a wired aux input, which the Ultimate Ears Wonderboom lacks. Watch for: Bass doesn’t go as deep as class leaders.
Buy the Klipsch Groove if you want one new; the Ultimate Ears Wonderboom is discontinued, so only look for it used.
