Short answer: the Stormbox Blast, and it costs about half as much. It ranks #2 of 113 boombox speakers at $199.99; the Boombox 3 ranks #27 at $349.95, $149.96 more.
The Boombox 3 wins on real features the Blast doesn’t have. IP67 water resistance, a genuine power bank function, and PartyBoost pairing with up to 100 compatible JBL speakers, against dips in its own mid bass and a peak at 700Hz that our notes say keep it from matching the Blast’s mids and treble.
The Blast earns its ranking with the tuning itself. Bass almost as deep as a JBL Partybox 100, a neutral default tuning, and a reviewer EQ that became the firmware default.
Buy the Stormbox Blast for the far better measured sound at half the price. Buy the Boombox 3 for the water resistance and JBL’s ecosystem.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
A loud, fully waterproof boombox with a dedicated subwoofer, a 24 hour battery and power bank charging.
A boombox with bass and volume that rival bigger party speakers, quite neutral sound, and a 30 hour battery.
