Short answer: the JBL Partybox 310 for output and bass depth. The Sony SRS-XP500 is a well-balanced 20W 3-way design with dual passive radiators, clear highs, detailed mids and punchy bass, but it is not as loud and its bass is not as deep as a Partybox 100 or 110. The 310 counters with the absolute deepest bass of any battery powered speaker, the most balanced sound in its class and handle and wheels, though it is very large.
Buy the JBL Partybox 310 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Sony ULT Tower 7 instead.
Water resistance is not close: the JBL Partybox 310 is rated at IPX4 (splashing), well ahead of the Sony SRS-XP500 at no water resistance.
