Short answer: the Sonos Move 2. It ranks #28 of 115 large speakers by sound quality, rated 4.1/5, at $480. The Marshall Stockwell III ranks #79, rated 3.0/5, at $249.99, $230.01 cheaper, which does not close the gap in sound quality.
The Marshall Stockwell III is the longer-running, lighter option. 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 24 for the Sonos Move 2. At 2.9 lbs (1.3 kg) it weighs much less than the Sonos Move 2 at 6.6 lbs (3 kg). It supports AAC Bluetooth, which the Sonos Move 2 lacks. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The Sonos Move 2 is the better-sounding choice. A Wi-Fi and Bluetooth portable with warm, full sound, clear mids and a long battery for moving around the home. The tradeoff: Not very loud.
Buy the Sonos Move 2. It is rated higher for sound quality, and the $230.01 you would save on the Marshall Stockwell III does not close the gap.
