Short answer: the Onn Pro X Large Boom Boombox. It ranks #49 of 113 boombox speakers by sound quality (rated 3.4/5) at $199 and is still sold new; the Soundcore Motion Boom+ ranks #72 (rated 2.9/5) and is discontinued, so it is only an option used. The Soundcore Motion Boom+’s replacement, the Soundcore Boom 2 Plus, is rated 3.6/5 at $169.99.
The Onn Pro X Large Boom Boombox is the better-sounding pick. A powerful, waterproof party boombox with a 20 hour battery and light modes at a low price. The tradeoff: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
The Soundcore Motion Boom+ is the lighter option. A rugged, waterproof stereo speaker that floats, with a 20 hour battery and app EQ. At 5.3 lbs (2.4 kg) it weighs much less than the Onn Pro X Large Boom Boombox at 17.2 lbs (7.8 kg). Watch for: Default presets are all warm sounding with rolled off treble.
Buy the Onn Pro X Large Boom Boombox. It is rated higher for sound quality and still sold new, while the Soundcore Motion Boom+ is discontinued.
