Short answer: the Zealot ZE41. It ranks #17 of 98 boombox speakers by sound quality, rated 4.1/5, at $259.90. The JBL Partybox On the Go ranks #64, rated 3.0/5, at $249.95, $9.95 cheaper, which does not close the gap in sound quality.
The Zealot ZE41 is the better-sounding pick. The absolute best value for the bass performance, play time and max volume in the boombox class. It links with other speakers (PartyAdd up to 100 speakers), which the JBL Partybox On the Go cannot. It has an adjustable EQ, which the JBL Partybox On the Go lacks. Watch for: The heaviest and biggest boombox speaker around.
The JBL Partybox On the Go is the lighter pick. A wireless microphone is included. At 16.5 lbs (7.5 kg) it weighs noticeably less than the Zealot ZE41 at 25.3 lbs (11.48 kg). The catch: Battery life is short, and its sound trails the rest of the Partybox line.
Buy the Zealot ZE41. It is rated higher for sound quality, and the $9.95 you would save on the JBL Partybox On the Go does not close the gap.

Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
