Short answer: the JBL Boombox 3. It ranks #27 of 112 boombox speakers by sound quality, rated 3.8/5, at $349.95. The Tronsmart Bang Max ranks #52, rated 3.4/5, at $229.99, $119.96 cheaper, which does not close the gap in sound quality.
The JBL Boombox 3 is the better-sounding choice. A loud, fully waterproof boombox with a dedicated subwoofer, a 24 hour battery and power bank charging. It links with other speakers (PartyBoost up to 100 speakers), which the Tronsmart Bang Max cannot. Watch for: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
What the Tronsmart Bang Max does well: A loud, feature packed party speaker with big bass, app EQ, lights, and separate mic and guitar inputs. It has an adjustable EQ, which the JBL Boombox 3 lacks. The catch: Its bass-first tuning prioritizes impact over accuracy: upper mids and lower treble can sound unnatural, while fine midrange and treble detail are limited.
Buy the JBL Boombox 3. It is rated higher for sound quality, and the $119.96 you would save on the Tronsmart Bang Max does not close the gap.
