Short answer: the JBL Boombox 3 Wifi. It ranks #26 of 112 boombox speakers by sound quality, rated 3.8/5, at $389.95. The Yeahbox Sonic Boom Max 3 ranks #59, rated 3.2/5, at $228.99, $160.96 cheaper, which does not close the gap in sound quality.
The case for the Yeahbox Sonic Boom Max 3: A large party speaker with powerful bass, a big fast charging battery and app EQ for outdoor parties. It has an adjustable EQ, which the JBL Boombox 3 Wifi lacks. The tradeoff: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
The JBL Boombox 3 Wifi is the better-sounding option. A big, waterproof stereo boombox with Wi-Fi, a long battery and enough volume for any outdoor party. The catch: Bass boosted.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality, and saving $160.96 with the Yeahbox Sonic Boom Max 3 does not make up for the sound-quality gap.
