Short answer: the Treblab HD-Max for output and battery, the Sony ULT Field 5 for protection. The HD-Max puts out 50W with four drivers and tested 22.4 hours, or 25+ hours at 50% volume, at $123.47, though its upper bass is boosted and it has not much lower bass. The Sony is IP67 rated at $348, but its bass is not as deep as others and the sound is just okay.
Buy the Sony ULT Field 5. It is rated higher for sound quality, and the $224.53 you would save on the Treblab HD-Max does not close the gap.
