Short answer: the Marshall Stockwell III if sound quality matters most, the Xdobo X8 Max if price matters most. The Marshall Stockwell III ranks #79 of 115 large speakers, rated 3.0/5, at $249.99. The Xdobo X8 Max ranks #83, rated 2.9/5, at $105.99, $144 cheaper.
The Marshall Stockwell III is the longer-running, lighter choice. A stylish, rugged speaker with a very long battery you can swap yourself, a detailed app EQ, and power bank charging. It is rated for 40 hours of battery against 15 for the Xdobo X8 Max. At 2.9 lbs (1.3 kg) 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. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The Xdobo X8 Max is the tougher choice. A feature packed waterproof boombox with a huge battery, power bank output, and enough volume for outdoor background music. It is rated IPX7 against IP55 for the Marshall Stockwell III. The catch: 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 Stockwell III if sound quality is the priority over the price, or the Xdobo X8 Max if the price is the priority over sound quality.
