Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #89 of 144 medium speakers by sound quality, rated 2.9/5, at $59.99. The Skullcandy Terrain XT ranks #136, rated 2.1/5, at $38.77, $21.22 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 144 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
What the Ultimate Ears Wonderboom 4 does well: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Skullcandy Terrain XT does well: IPX7 rated with a nylon wrist wrap for carrying. The tradeoff: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality, and the $21.22 you would save on the Skullcandy Terrain XT does not close the gap.

Pros: IPX7 rated with a nylon wrist wrap for carrying. 14 hour battery life. Multi-Link pairs it with other Skullcandy speakers.
Cons: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble. Costs more than the standard Terrain without sounding better.
