Short answer: the Sonos Move 2 for better sound quality, the Marshall Stockwell III for the lower price. The Sonos Move 2 ranks #25 of 78 large speakers at $495.26. The Marshall Stockwell III ranks #56 at $249.99, $245.27 cheaper.
What the Marshall Stockwell III offers: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. Doubles as a USB-C power bank. IP55 dust/water resistance. App includes parametric EQ, a Soundstage widening control, and wall/corner placement compensation. Endless-rotation control knobs. Watch for: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then. Bass tends to sound resonant and boomy, with reported frequency cancellation and phase issues on complex material that EQ doesn’t fully resolve. Oluv’s A/B testing against the outgoing Stockwell 2 finds the default tuning muffled and muddy enough to prefer the seven-year-old original out of the box, and output loses dynamics and bass while turning harsh well below maximum volume. No aptX support.
What the Sonos Move 2 offers: Warm sounding with somewhat rolled off treble. Slightly better midrange clarity than the Move 1. Watch for: Not very loud. This may have some of the same issues at full volume that the Move 1 had too, but I’ll need more sound samples at full volume to verify.
Buy the Marshall Stockwell III if the price matters more than sound quality. Buy the Sonos Move 2 if sound quality matters more than the price.
There is a real battery-life gap here: the Marshall Stockwell III is rated for 40 hours, the Sonos Move 2 only 24 hours.
