Short answer: the JBL Xtreme 4. It ranks #44 of 115 large speakers by sound quality, rated 3.8/5, at $309.95. The Xdobo X8 Max ranks #83, rated 2.9/5, at $105.99, $203.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Xtreme 4 is the better-sounding, longer-running choice. A rugged, waterproof speaker with clear, punchy sound, a swappable battery, a power bank and excellent real world battery life. It is rated for 24 hours of battery against 15 for the Xdobo X8 Max. At 4.6 lbs (2.1 kg) it weighs noticeably less than the Xdobo X8 Max at 6.3 lbs (2.86 kg). It links with other speakers (Auracast), which the Xdobo X8 Max cannot. The catch: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
Why pick the Xdobo X8 Max: A feature packed waterproof boombox with a huge battery, power bank output, and enough volume for outdoor background music. It keeps a wired aux input, which the JBL Xtreme 4 lacks. 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.
Buy the JBL Xtreme 4. It is rated higher for sound quality, and the $203.96 saving on the Xdobo X8 Max is not enough to make up the difference.
