Short answer: the W-King D10, if you are buying new, though neither ranks well in its class. The Diamondboxx M3 ranks higher than it (#76 vs #79 of 112 boombox speakers, 2.8/5 vs 2.7/5) but is discontinued, so only consider it used; the W-King D10 is still sold new at $84.97. Both are rated below 3.0/5 among the 112 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
The W-King D10 is the lighter, tougher option. An inexpensive boombox with a 42 hour battery, water resistance, a power bank and a karaoke mic input. At 7.9 lbs (3.6 kg) it weighs noticeably 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: Upper bass boost, bass not that deep.
The case for the Diamondboxx M3: A compact, very loud boombox with a powerful amplifier and a choice of large battery packs. Watch for: Despite its output, bass does not reach as deep as the best large portables and can distort when pushed hard.
Buy the W-King D10 new; the Diamondboxx M3 is no longer sold new, so it only makes sense as a used find.
