Short answer: a tie on sound quality, though neither ranks well in its class. Both are rated 2.9/5 (#111 and #110 of 179 medium speakers) at nearly the same price ($80 vs $79.99), so choose on features and fit. Both are rated below 3.0/5 among the 179 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
Buy the Ultimate Ears Wonderboom 2 or the Ultimate Ears Wonderboom 3 on features: they are rated the same for sound quality at close to the same price.
