Last updated: August 18, 2026

Short answer: the Marshall Tufton for better sound quality, the Zealot S78 for the lower price. The Marshall Tufton ranks #60 of 73 boombox speakers at $450. The Zealot S78 ranks #73 at $91.38, $358.62 cheaper.

On the Marshall Tufton side: 20 hour battery life; 2.5 hour full charge, or 20-min quick-charge for 4 hours of play. Set against that: Not much lower bass, upper bass boomy, boosted treble, not very balanced overall.

What the Zealot S78 gets right: 120W RMS output with 150W peak power, exceptional 40-hour battery life, power bank function, IP67 waterproof, EQ with multiple modes, dual woofers with tweeters and passive radiators, MicroSD and USB playback, AUX input. The catch: Gets distorted above 50%.

Buy the Marshall Tufton 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 both of these and look higher up the 73 boombox speakers instead.

If water resistance matters to you, the Zealot S78 at IP67 (brief submersion) holds up far better than the Marshall Tufton at IPX2 (light drips).
