Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Ultimate Ears Wonderboom 4 ranks #89 of 144 medium speakers by sound quality at $59.99; the Xdobo X8 Max ranks #61 of 82 large speakers by sound quality at $73. Both are rated below 3.0/5 for their class (144 medium speakers and 82 large speakers), so if sound quality matters, look higher up the rankings.
What the Ultimate Ears Wonderboom 4 does well: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
The case for the Xdobo X8 Max: 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. The catch: The voicing is bass-heavy with thin, boosted highs that can turn harsh, and reviews report distortion rather than clean dynamics when pushed hard.
Buy the Ultimate Ears Wonderboom 4 ($59.99) for a medium speaker; the Xdobo X8 Max ($73) suits a large speaker instead.

Xdobo X8 Max: $73 eBay
Pros: 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. Measured bass extension of ~52Hz (-10dB).
Cons: 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.
