Short answer: the JBL Partybox Encore Essential. It ranks #7 of 73 boombox speakers by sound quality at $329.95; the Sony SRS-XG500 ranks #45 and costs $349, which makes this an easy call rather than a real tradeoff.
What the JBL Partybox Encore Essential offers: A great sounding somewhat boosted bass party speaker. Watch for: Only 6 hours of battery at medium volume. Poor Water rating.
What the Sony SRS-XG500 offers: 30 hour battery life; 10-min quick-charge gives 3 hours. Battery care function stops charging at 90% to extend longevity. IP66 water/dust resistant. Two USB-A ports (one charges devices), mic/guitar inputs, AUX. Party mode links 100+ speakers. Watch for: Thuddy upper bass, not as deep bass as others. Speaker will not remain at max volume and will turn itself down automatically.
Buy the JBL Partybox Encore Essential. It ranks higher for sound quality than the Sony SRS-XG500 and costs less, so there is no real case for the other one.
If battery life is a priority, the Sony SRS-XG500 is rated for 30 hours versus 6 hours for the JBL Partybox Encore Essential.
