Short answer: the Tronsmart Bang Max if sound quality matters most, the Zealot S78 if price matters most. The Tronsmart Bang Max ranks #36 of 75 boombox speakers at $229.99. The Zealot S78 ranks #75 at $159.68, $70.31 cheaper.
What the Tronsmart Bang Max offers: A powerful, feature-rich party speaker with loud, bass-rich output, app EQ, power-bank capability, lighting, TWS/multi-speaker linking, and separate microphone and guitar inputs with independent level control. Reviews find it can fill a large room even at moderate volume, while SoundPulse or custom EQ gives it useful flexibility for parties and casual karaoke. Watch for: Its bass-first tuning prioritizes impact over accuracy: upper mids and lower treble can sound unnatural, while fine midrange and treble detail are limited. Deep Bass mode can swallow the rest of the mix, volume control is imprecise and some reviewers hear distortion above roughly 98dB. It is a party tool, not a neutral monitor.
What the Zealot S78 offers: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. Reviews find it very loud with useful bass and long claimed battery life, making it a credible choice for outdoor gatherings. Watch for: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting. It has no app-based EQ, and the bass and midrange refinement do not match better-established boombox speakers; assess its sound in person if tonal accuracy matters.
Buy the Tronsmart Bang Max if sound quality matters more than the price. Buy the Zealot S78 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Zealot S78. It ranks near the bottom of the 75 boombox speakers, so look higher up the list instead.
