Short answer: the JBL Partybox Encore Essential. It ranks #8 of 98 boombox speakers by sound quality, rated 4.2/5, at $329.95. The W-King X20 ranks #41, rated 3.5/5, at $229.99, $99.96 cheaper, which does not close the gap in sound quality.
The JBL Partybox Encore Essential is the better-sounding pick. It links with other speakers (PartyBoost up to 100 speakers), which the W-King X20 cannot.
The W-King X20 is the longer-running, tougher pick. It is rated for 24 hours of battery against 6 for the JBL Partybox Encore Essential. It is rated IPX6 against IPX4 for the JBL Partybox Encore Essential. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality, and the $99.96 you would save on the W-King X20 does not close the gap.
