Short answer: the Xdobo X8 Max ranks #57 of 78 large speakers by sound quality at $73; the onn Portable FM Boombox ranks #23 at $74.83. With prices this close, go by the sound-quality ranking rather than the cost.
What the Xdobo X8 Max offers: A 2.86kg, feature-packed boombox with claimed 100W output, a 20,000mAh battery, USB-C charging, power-bank output, IPX7 protection, aux and microSD playback, speakerphone capability and TWS. Dual woofers and tweeters provide enough output for outdoor background music, with a roughly 52Hz -10dB bass point. Watch for: The voicing is bass-heavy with thin, boosted highs that can turn harsh, and reviews report distortion rather than clean dynamics when pushed hard. There is no app or user EQ to correct it; the limited tested water resistance and less-refined tuning make it a poor pick for critical listening.
What the onn Portable FM Boombox offers: Extremely good value. Reasonably deep bass, though not as deep as something like the JBL Xtreme 3, Soundcore Boom 2, or Tribit Stormbox Lava. IPX7 waterproof and floats. FM radio with 10 presets. 6 multicolor LED lighting effects. Can run on battery or corded power. Watch for: Reasonable frequency response, but not quite as smooth as some of the top-ranked speakers in this size. No custom EQ. Only available in the United States and Canada.
