Short answer: the Sony ULT Field 1 for battery and waterproofing, the Tribit Xsound Go for balance. The Field 1 is IP67 rated and survives a 1m dunk, runs 28+ hours in real-world use with ULT bass boost off and stereo-pairs with a second Field 1, though it has an upper-midrange peak and rolled-off treble. The Xsound Go has a well-balanced sound and is very light at 13.4 oz and IPX7 rated with up to 24 hours of battery, but it lacks quite a bit of bass.
Buy the Tribit Xsound Go. Both are rated the same for sound quality, and it costs $63.01 less than the Sony ULT Field 1.
There is a real battery-life gap here: the Tribit Xsound Go is rated for 24 hours, the Sony ULT Field 1 only 12 hours.
