Short answer: the Marshall Middleton II. It ranks #31 of 115 large speakers by sound quality, rated 4.1/5, at $279.99. The Xdobo X8 Max ranks #83, rated 2.9/5, at $105.99, $174 cheaper, which does not close the gap in sound quality.
The Marshall Middleton II is the better-sounding, deeper-bass pick. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and an app EQ. Its bass reaches about 38Hz before falling 10dB, against 52Hz for the Xdobo X8 Max. It is rated for 30 hours of battery against 15 for the Xdobo X8 Max. At 4 lbs (1.8 kg) it weighs noticeably less than the Xdobo X8 Max at 6.3 lbs (2.86 kg). Watch for: Bass boosted which drowns out the midrange.
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. The tradeoff: 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 Marshall Middleton II. It is rated higher for sound quality, and the $174 you would save on the Xdobo X8 Max does not close the gap.
