Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #109 of 179 medium speakers by sound quality, rated 2.9/5, at $64.99; the Skullcandy Terrain XT ranks #170, rated 2.1/5, at $59.99. With prices this close, go by the sound-quality ranking rather than the cost. 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.
The Ultimate Ears Wonderboom 4 is the better-sounding, lighter pick. A small, tough waterproof speaker with a strap loop and USB-C charging, easy to clip on a bag for outdoor trips. At 0.9 lbs (420 g) it weighs much less than the Skullcandy Terrain XT at 1.6 lbs (720 g). Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Skullcandy Terrain XT does well: A waterproof speaker with a wrist wrap for carrying and pairing with other Skullcandy speakers. It links with other speakers (SKDY Multi-Link, up to 99 speakers), which the Ultimate Ears Wonderboom 4 cannot. The catch: 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 $5 you would save on the Skullcandy Terrain XT does not close the gap.
