Short answer: the Sony ULT Field 3 if sound quality matters most, the Skullcandy Terrain if price matters most. The Sony ULT Field 3 ranks #71 of 179 medium speakers, rated 3.4/5, at $208. The Skullcandy Terrain ranks #169, rated 2.1/5, at $49.93, $158.07 cheaper.
The Sony ULT Field 3 is the better-sounding, longer-running option. A rugged waterproof stereo speaker with long battery life, a detailed app EQ, a shoulder strap and a phone charging port. It is rated for 24 hours of battery against 14 for the Skullcandy Terrain. It supports LDAC Bluetooth, which the Skullcandy Terrain lacks. It has an adjustable EQ, which the Skullcandy Terrain lacks. The catch: Sounds a bit hollow, a bit boosted in the treble.
The Skullcandy Terrain is the lighter choice. A waterproof speaker with a wrist wrap for carrying and pairing with other Skullcandy speakers. At 1 lbs (458 g) it weighs much less than the Sony ULT Field 3 at 2.6 lbs (1.2 kg). Watch for: No bass, very rolled off treble.
Buy the Sony ULT Field 3 if sound quality matters more than the price. Buy the Skullcandy Terrain if the price matters more than sound quality.
