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 ranks #135, rated 2.1/5, at $49.94, $48.06 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. Watch for: Upper midrange peak, rolled off treble.
The case for the Skullcandy Terrain: IPX7 rated with a nylon wrist wrap for carrying. The catch: No bass, very rolled off treble.
Buy the Sony ULT Field 1. It is rated higher for sound quality, and the $48.06 saving on the Skullcandy Terrain is not enough to make up the difference.
