Short answer: the Zealot S89. It ranks #16 of 73 boombox speakers by sound quality at $246.99; the JBL Boombox 2 ranks #29 and costs $499.95, which makes this an easy call rather than a real tradeoff.
What the Zealot S89 offers: A great value for the bass performance, play time and max volume in the boombox class. Likely the same internals as the Zealot ZE21 Watch for: On the heavy side. 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 Boombox 2 offers: 24 hour battery life (default volume); 20+ hours even at 60% volume. IPX7 rated. Doubles as a power bank. Bluetooth 5.1 with PartyBoost (up to 100 speakers). Reaches 101dB. Watch for: Somewhat bass heavy and boomy.
Buy the Zealot S89. It ranks higher for sound quality than the JBL Boombox 2 and costs less, so the other one has nothing left to offer.
If battery life is a priority, the Zealot S89 is rated for 40 hours versus 24 hours for the JBL Boombox 2.
