These sit in different size classes, so this is not a straight ranking comparison. The Soundcore Boom 3i ranks #31 of 179 medium speakers by sound quality at $118.99; the Xdobo X8 Max ranks #88 of 120 large speakers by sound quality at $105.99.
The Soundcore Boom 3i is the lighter choice. A warm, punchy waterproof speaker that sounds great and is a strong value. At 1.7 lbs (783 g) it weighs much less than the Xdobo X8 Max at 6.3 lbs (2.86 kg). It supports AAC Bluetooth, which the Xdobo X8 Max lacks. It has an adjustable EQ, which the Xdobo X8 Max lacks. The catch: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
What the Xdobo X8 Max does well: 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 Soundcore Boom 3i lacks. It plays in stereo from a single unit, unlike the Soundcore Boom 3i. 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 Soundcore Boom 3i at $118.99 for a medium speaker, or the Xdobo X8 Max at $105.99 for a large speaker instead.
