Short answer: the W-King X10, if you are buying new, though neither ranks well in its class. The Diamondboxx M3 ranks higher than it (#76 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, and the Tribit Stormbox Blast, ranked #2 at $179.99, is a better place to start if sound quality matters.
The W-King X10 is the lighter, tougher option. A cheap, waterproof stereo boombox with a very long battery, loud output and a power bank for charging your phone. At 6.5 lbs (2.95 kg) it weighs much less than the Diamondboxx M3 at 11 lbs (5 kg). It is rated IPX6, while the Diamondboxx M3 has no water resistance. It has an adjustable EQ, which the Diamondboxx M3 lacks. The catch: Heavily rolled off treble, less bass than the top ranked.
The Diamondboxx M3 is the better-sounding pick. A compact, very loud boombox with a powerful amplifier and a choice of large battery packs. The catch: Despite its output, bass does not reach as deep as the best large portables and can distort when pushed hard.
Buy the W-King X10, since the Diamondboxx M3 is discontinued and only worth hunting down used.
