Short answer: the W-King X10, if you are buying new, though neither ranks well in its class. The Demerbox DB2 ranks higher than it (#74 vs #93 of 112 boombox speakers, 2.8/5 vs 2.3/5) but is discontinued, so only consider it used; the W-King X10 is still sold new at $80. Both are rated below 3.0/5 among the 112 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
Why pick the W-King X10: A cheap, waterproof stereo boombox with a very long battery, loud output and a power bank for charging your phone. It has an adjustable EQ, which the Demerbox DB2 lacks. The catch: Heavily rolled off treble, less bass than the top ranked.
The Demerbox DB2 is the better-sounding option. A nearly indestructible waterproof speaker built from a Pelican case, with a 40 hour battery and dry storage. Watch for: Bass is not as deep as better speakers.
Buy the W-King X10 new; the Demerbox DB2 is no longer sold new, so it only makes sense as a used find.
