Short answer: the Ultimate Ears Wonderboom 4 on price and size, the Klipsch Groove for battery and design, though neither ranks well in its class. The Groove/Heritage Groove has a distinctive mid-century design, plus about 8 hours of battery, but it is not stereo, its bass does not go as deep as others its size and distorts at higher levels. The Wonderboom 4 is smaller and cheaper at $78.95, though its bass is not as deep as the top-ranked speakers and is a little thuddy. Both are rated below 3.0/5 among the 157 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
Buy the Ultimate Ears Wonderboom 4 when sound quality outweighs the price for you, and the Klipsch Groove when the price outweighs sound quality instead.
There is a real battery-life gap here: the Ultimate Ears Wonderboom 4 is rated for 14 hours, the Klipsch Groove only 8 hours.
If water resistance matters to you, the Ultimate Ears Wonderboom 4 at IP67 (brief submersion) holds up far better than the Klipsch Groove at IPX4 (splashing).

Pros: Pretty balanced sound in a compact, splash-resistant form factor. IPX4 water resistance and ~8 hour battery life make it durable for outdoor and poolside use. 3-inch high excursion full-range driver paired with dual side-firing passive radiators.
Cons: Not stereo. Bass doesn’t go as deep as class leaders. Distortion sets in at higher output levels. Older Bluetooth 4.0 architecture without app EQ.
