Short answer: the Marshall Stockwell III. It ranks #84 of 120 large speakers by sound quality, rated 3.0/5, at $249.99. The DOSS Extreme Boom ranks #115, rated 2.1/5, at $75.99, $174 cheaper, which does not close the gap in sound quality.
The Marshall Stockwell III is the better-sounding, longer-running 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 30 for the DOSS Extreme Boom. At 2.9 lbs (1.3 kg) it weighs much less than the DOSS Extreme Boom at 5.6 lbs (2.52 kg). It supports AAC Bluetooth, which the DOSS Extreme Boom lacks. Watch for: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The DOSS Extreme Boom is the tougher choice. An affordable waterproof outdoor speaker with a long rated battery, power bank output, and bass heavy sound for casual parties. It is rated IPX7 against IP55 for the Marshall Stockwell III. The catch: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the Marshall Stockwell III. It is rated higher for sound quality, and the $174 saving on the DOSS Extreme Boom is not enough to make up the difference.
