JBL Partybox Encore vs W-King X20

Last updated: October 12, 2026

Short answer: the JBL Partybox Encore 2, if you are buying new. The JBL Partybox Encore ranks higher than the W-King X20 (#7 vs #41 of 98 boombox speakers) but is discontinued; its replacement, the JBL Partybox Encore 2, is rated 4.4/5 at $330 and is still sold new.

JBL Partybox Encore vs W-King X20

The JBL Partybox Encore is the better-sounding choice. A great sounding party speaker with somewhat boosted bass and two included wireless microphones. It links with other speakers (PartyBoost up to 100 speakers), which the W-King X20 cannot. The catch: Only IPX4 splash resistance.

The W-King X20 is the longer-running, tougher option. It is rated for 24 hours of battery against 6 for the JBL Partybox Encore. It is rated IPX6 against IPX4 for the JBL Partybox Encore. The tradeoff: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.

Buy the JBL Partybox Encore 2, the replacement for the discontinued JBL Partybox Encore; it is rated higher for sound quality than the W-King X20.
