Short answer: the Diamondboxx M3 for better sound quality, the W-King X10 for the lower price. The Diamondboxx M3 ranks #53 of 75 boombox speakers at $700. The W-King X10 ranks #64 at $80, $620 cheaper.
What the W-King X10 offers: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ with indoor/outdoor modes, dual woofers with tweeters and passive radiators, Bluetooth 5.0 with 100ft range, MicroSD and USB playback, AUX input, TWS stereo pairing Watch for: Heavily rolled off treble, less bass than the top ranked.
What the Diamondboxx M3 offers: An unusually compact 5kg high-output boombox, with a claimed 200W RMS Class A/B amplifier, 114dB maximum level, active crossovers and a choice of large battery packs. It has aux input, USB-C power and TWS pairing, while the aluminum heat sink is designed to sustain loud playback without thermal shutdown. Watch for: Despite its output, bass does not reach as deep as the best large portables and can distort when pushed hard. The treble-forward tuning can sound aggressive, there is no app or EQ to correct it, and the lack of a water rating makes it a poor match for poolside or rough-weather use.
Buy the W-King X10 if the price is the priority over sound quality, or the Diamondboxx M3 if sound quality is the priority over the price.
Skip the W-King X10 if sound quality matters to you. It ranks near the bottom of the 75 boombox speakers.
If water resistance matters to you, the W-King X10 at IPX6 (powerful water jets) holds up far better than the Diamondboxx M3 at no water resistance.
