Short answer: the Yeahbox Sonic Boom Max 3 if sound quality matters most, the Onn Medium Party Speaker Gen 2 if price matters most. The Yeahbox Sonic Boom Max 3 ranks #59 of 112 boombox speakers, rated 3.2/5, at $228.99. The Onn Medium Party Speaker Gen 2 ranks #65, rated 3.1/5, at $90, $138.99 cheaper.
The Onn Medium Party Speaker Gen 2 is the lighter choice. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. At 11 lbs (5 kg) it weighs noticeably less than the Yeahbox Sonic Boom Max 3 at 16.8 lbs (7.64 kg). The catch: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
What the Yeahbox Sonic Boom Max 3 does well: 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 Onn Medium Party Speaker Gen 2 lacks. It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. The catch: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
Buy the Onn Medium Party Speaker Gen 2 if the price is the priority over sound quality, or the Yeahbox Sonic Boom Max 3 if sound quality is the priority over the price.
