Short answer: the Sony ULT Field 1. It ranks #81 of 144 medium speakers by sound quality, rated 3.1/5, at $98. The Skullcandy Terrain XL ranks #134, rated 2.1/5, at $79.99, $18.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Sony ULT Field 1 does well: IP67 rated, survives drops and 1m submersion. Watch for: Upper midrange peak, rolled off treble.
Why pick the Skullcandy Terrain XL: The loudest and longest-running of the Terrain line at 95dB and 18 hours, and the only one with a built-in microphone. Watch for: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
Buy the Sony ULT Field 1. It is rated higher for sound quality, and saving $18.01 with the Skullcandy Terrain XL does not make up for the sound-quality gap.
There is a real battery-life gap here: the Skullcandy Terrain XL is rated for 18 hours, the Sony ULT Field 1 only 12 hours.

Skullcandy Terrain XL: $79.99 Amazon eBay
Pros: The loudest and longest-running of the Terrain line at 95dB and 18 hours, and the only one with a built-in microphone. IPX7 rated with a nylon wrist wrap. 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. The extra size buys volume and runtime, not better sound.
