Short answer: the Zealot ZE41. It ranks #14 of 73 boombox speakers by sound quality at $289.90; the JBL Partybox On the Go ranks #44 and costs $300, so there is not much of a tradeoff to weigh.
What the Zealot ZE41 offers: The absolute best value for the bass performance, play time and max volume in the boombox class. Watch for: 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.
What the JBL Partybox On the Go offers: Included wireless microphone. Watch for: Poor water rating. Horrible battery life. Probably the worst sounding of the Partybox line.
Buy the Zealot ZE41. It ranks higher for sound quality than the JBL Partybox On the Go and costs less, so the other one has nothing left to offer.
