Short answer: the JBL Partybox 330 for output and bass depth. The Sony SRS-XP500’s 20W 3-way system with dual passive radiators is well balanced, with 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 330 has a convenient handle and wheels, though its sound quality is nearly identical to the 310 and Stage 320 despite the power bump. The Sony SRS-XP500 is discontinued; its replacement is the Sony SRS-XV500.
Buy the JBL Partybox 330. It is rated higher for sound quality and still sold new, while the Sony SRS-XP500 is discontinued.
There is a real gap in water resistance: the JBL Partybox 330 at IPX4 (splashing) against the Sony SRS-XP500, which has no water resistance.
