Short answer: the JBL Partybox Encore 2. It ranks #4 of 113 boombox speakers by sound quality, rated 4.4/5, at $330. The Onn Pro X Large Boom Boombox ranks #49, rated 3.4/5, at $199, $131 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Partybox Encore 2 is the better-sounding choice. A compact karaoke party speaker with two wireless mics, better balanced sound than the original and a long battery. The catch: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
The Onn Pro X Large Boom Boombox is the longer-running, tougher pick. A powerful, waterproof party boombox with a 20 hour battery and light modes at a low price. It is rated for 20 hours of battery against 15 for the JBL Partybox Encore 2. It is rated IP67 against IPX4 for the JBL Partybox Encore 2. Watch for: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the JBL Partybox Encore 2. It is rated higher for sound quality, and the $131 you would save on the Onn Pro X Large Boom Boombox does not close the gap.
