Short answer: the Teufel Rockster Cross on measured sound quality, the Xdobo X8 Max on price. The Teufel Rockster Cross ranks #21 of 78 large speakers at $199.99. The Xdobo X8 Max ranks #57 at $73, $126.99 cheaper.
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 Teufel Rockster Cross offers: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver - better suited to rock and jazz. Nicer upper-bass detail than the JBL Xtreme 4. Punchy, well-controlled bass that suits rock music, unlike the Soundcore Boom 2 Plus’s overboosted, uncontrolled bass even at stock tuning. Clear, detailed audio with good vocal presence and solid Bluetooth codec support even a couple years after release. Watch for: Outdoor mode can sound somewhat harsh due to the 4khz peak. Not as deep or full-sounding in the bass as the JBL Xtreme 4.
