Short answer: the Zealot ZE51. It ranks #16 of 112 boombox speakers by sound quality, rated 4.1/5, at $235.33. The Tronsmart Bang Max ranks #52, rated 3.4/5, at $229.99, $5.34 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Zealot ZE51 is the better-sounding pick. A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. The catch: The Zealot ZE41 still wins on raw bass depth and price.
The Tronsmart Bang Max is the longer-running, lighter pick. A loud, feature packed party speaker with big bass, app EQ, lights, and separate mic and guitar inputs. It is rated for 24 hours of battery against 4 for the Zealot ZE51. At 12.8 lbs (5.8 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). 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 Zealot ZE51. It is rated higher for sound quality, and the $5.34 saving on the Tronsmart Bang Max is not enough to make up the difference.
