Short answer: the Sony ULT Field 3. It ranks #71 of 179 medium speakers by sound quality, rated 3.4/5, at $208. The Skullcandy Terrain XL ranks #168, rated 2.1/5, at $79.99, $128.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Sony ULT Field 3 is the better-sounding, longer-running pick. 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 18 for the Skullcandy Terrain XL. It supports LDAC Bluetooth, which the Skullcandy Terrain XL lacks. It has an adjustable EQ, which the Skullcandy Terrain XL lacks. The catch: Sounds a bit hollow, a bit boosted in the treble.
The Skullcandy Terrain XL is the lighter choice. A very loud, long running Terrain speaker, waterproof with a wrist wrap and a built in microphone. At 1.4 lbs (635 g) it weighs much less than the Sony ULT Field 3 at 2.6 lbs (1.2 kg). The catch: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
Buy the Sony ULT Field 3. It is rated higher for sound quality, and saving $128.01 with the Skullcandy Terrain XL does not make up for the sound-quality gap.
