Short answer: the Marshall Kilburn II. It ranks #43 of 115 large speakers by sound quality, rated 3.8/5, at $219. The Xdobo X8 Max ranks #83, rated 2.9/5, at $105.99, $113.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Marshall Kilburn II is the better-sounding, longer-running choice. A rugged Marshall styled stereo speaker with a leather handle, quick charging and a sound that suits rock. It is rated for 20 hours of battery against 15 for the Xdobo X8 Max. The catch: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The Xdobo X8 Max is the deeper-bass, tougher option. A feature packed waterproof boombox with a huge battery, power bank output, and enough volume for outdoor background music. Its bass reaches about 52Hz before falling 10dB, against 58Hz for the Marshall Kilburn II. It is rated IPX7 against IPX2 for the Marshall Kilburn II. 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 Marshall Kilburn II. It is rated higher for sound quality, and the $113.01 saving on the Xdobo X8 Max is not enough to make up the difference.
