Short answer: the onn Pro X Large Boom Boombox, if you are buying new. The JBL Partybox Encore ranks higher than it (#7 vs #44 of 91 boombox speakers, 4.3/5 vs 3.4/5) but is discontinued, so only consider it used; the onn Pro X Large Boom Boombox is still sold new at $199.
The JBL Partybox Encore is the better-sounding option. A great sounding party speaker with somewhat boosted bass and two included wireless microphones. The catch: Only IPX4 splash resistance.
The onn Pro X Large Boom Boombox is the longer-running, tougher option. High rated power for the price at 180W RMS (540W peak). It is rated for 20 hours of battery against 6 for the JBL Partybox Encore. It is rated IP67 against IPX4 for the JBL Partybox Encore. The catch: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the onn Pro X Large Boom Boombox new; the JBL Partybox Encore is no longer sold new, so it only makes sense as a used find.
