Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Boombox 2 is the better pick: it ranks #45 of 113 boombox speakers by sound quality (rated 3.5/5), against #72 (rated 2.9/5) for the Soundcore Motion Boom+. If you want one new, the JBL Boombox 4 replaces the JBL Boombox 2 and is rated 4.0/5 at $549.95.
The JBL Boombox 2 is the better-sounding, deeper-bass option. A waterproof boombox with a long battery that also charges your phone, and linking for many speakers. Its bass reaches about 46Hz before falling 10dB, against 52Hz for the Soundcore Motion Boom+. The tradeoff: Somewhat bass heavy and boomy.
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 JBL Boombox 2 at 13 lbs (5.9 kg). It has an adjustable EQ, which the JBL Boombox 2 lacks. The catch: Default presets are all warm sounding with rolled off treble.
Buy the JBL Boombox 2 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Boombox 4, which replaces the JBL Boombox 2.
