Short answer: the Yeahbox Sonic Boom Ultra on measured sound quality, the Zealot ZE01 on price. The Yeahbox Sonic Boom Ultra ranks #11 of 112 boombox speakers, rated 4.2/5, at $388. The Zealot ZE01 ranks #38, rated 3.7/5, at $126.02, $261.98 cheaper.
The Yeahbox Sonic Boom Ultra is the better-sounding choice. A massively loud boombox with deep bass, long battery life, and HDMI ARC so it can double as a TV soundbar. The catch: The 500W peak-power rating doesn’t fully hold up: it gets noisy above roughly 80-90% volume, and the midrange isn’t fully refined, sometimes sitting a touch too forward.
The Zealot ZE01 is the longer-running, lighter pick. An affordable stereo boombox with a 40 hour battery, water resistance and a power bank for long days outdoors. It is rated for 40 hours of battery against 24 for the Yeahbox Sonic Boom Ultra. At 13.2 lbs (6 kg) it weighs much less than the Yeahbox Sonic Boom Ultra at 24.3 lbs (11 kg). The tradeoff: A little rolled off up top and not that balanced through the rest of the range.
Buy the Yeahbox Sonic Boom Ultra if sound quality matters more than the price. Buy the Zealot ZE01 if the price matters more than sound quality.
