JBL Partybox Encore vs Sony SRS-XG500

Last updated: October 12, 2026

Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Partybox Encore is the better pick: it ranks #7 of 98 boombox speakers by sound quality (rated 4.3/5), against #65 (rated 3.0/5) for the Sony SRS-XG500. If you want one new, the JBL Partybox Encore 2 replaces the JBL Partybox Encore and is rated 4.4/5 at $330.

JBL Partybox Encore vs Sony SRS-XG500

The JBL Partybox Encore is the better-sounding, deeper-bass pick. A great sounding party speaker with somewhat boosted bass and two included wireless microphones. Its bass reaches about 38Hz before falling 10dB, against 49Hz for the Sony SRS-XG500. Watch for: Only IPX4 splash resistance.

The Sony SRS-XG500 is the longer-running, tougher choice. 30 hour battery life; 10-min quick-charge gives 3 hours. It is rated for 30 hours of battery against 6 for the JBL Partybox Encore. It is rated IP66 against IPX4 for the JBL Partybox Encore. It supports LDAC Bluetooth, which the JBL Partybox Encore lacks. Watch for: Thuddy upper bass, not as deep bass as others.

Buy the JBL Partybox Encore 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, buy the JBL Partybox Encore 2, which replaces the JBL Partybox Encore.
