Short answer: the Sony ULT Field 3. It ranks #61 of 144 medium speakers by sound quality, rated 3.4/5, at $138. The Skullcandy Terrain ranks #135, rated 2.1/5, at $49.94, $88.06 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Sony ULT Field 3: IP67 rated, dustproof and water resistant. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
Why pick the Skullcandy Terrain: IPX7 rated with a nylon wrist wrap for carrying. Watch for: No bass, very rolled off treble.
Buy the Sony ULT Field 3. It is rated higher for sound quality, and the $88.06 you would save on the Skullcandy Terrain does not close the gap.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 14 hours for the Skullcandy Terrain.

The Two Speakers In Full
Sony ULT Field 3: $138.00 Amazon eBay
Older models: the Sony XB33 (rated 3.4/5), the Sony SRS-XE300 (rated 2.8/5) and the Sony SRS-XB30 (rated 2.6/5).
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
