Short answer: the Tronsmart Bang Max. It ranks #52 of 112 boombox speakers by sound quality, rated 3.4/5, at $229.99. The Zealot S78 ranks #110, rated 2.0/5, at $91.38, $138.61 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Tronsmart Bang Max is the better-sounding choice. A loud, feature packed party speaker with big bass, app EQ, lights, and separate mic and guitar inputs. The tradeoff: Its bass-first tuning prioritizes impact over accuracy: upper mids and lower treble can sound unnatural, while fine midrange and treble detail are limited.
The Zealot S78 is the longer-running, lighter choice. A loud, rugged party speaker with full waterproofing, a power bank and wireless pairing for outdoor parties. It is rated for 40 hours of battery against 24 for the Tronsmart Bang Max. At 9.7 lbs (4.4 kg) it weighs noticeably less than the Tronsmart Bang Max at 12.8 lbs (5.8 kg). Watch for: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting.
Buy the Tronsmart Bang Max. It is rated higher for sound quality, and the $138.61 you would save on the Zealot S78 does not close the gap.
