Short answer: the JBL Xtreme, because the XG300 mostly buys an IP67 rating. The Sony SRS-XG300 is IP67 dust and waterproof, but our notes call it overly expensive. The JBL Xtreme’s 15-hour battery is the counterpoint, though it has issues with bass distortion at high volumes.
Buy the JBL Xtreme 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 Tribit Stormbox Lava instead.
