Short answer: the LG Xboom Stage 301. It ranks #25 of 75 boombox speakers by sound quality at $239.57; the Diamondboxx M3 ranks #53 and costs $700, which makes this an easy call rather than a real tradeoff.
What the LG Xboom Stage 301 offers: Wedge-style design works as a karaoke hub with removable/replaceable battery. Multiple standing positions. AI audio optimization via Dual-Bar lighting. Watch for: overpriced for what it is. Not the greatest frequency response.
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 LG Xboom Stage 301. It ranks higher for sound quality than the Diamondboxx M3 and costs less, so there is no real case for the other one.
Battery life favors the Diamondboxx M3: rated for 40 hours against 12 hours for the LG Xboom Stage 301.
If water resistance matters to you, the LG Xboom Stage 301 at IPX4 (splashing) holds up far better than the Diamondboxx M3 at no water resistance.
