Short answer: the LG Xboom Bounce. It ranks #30 of 78 large speakers by sound quality at $118.08; the Marshall Stockwell III ranks #56 and costs $249.99, so there is little reason to consider the other one.
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 LG Xboom Bounce offers: Unique spherical design. Up to 30 hours battery at 50% volume. IP67 + MIL-STD-810H military certification for impact/vibration/temperature. Multipoint pairing stays connected to two devices. LED lights add flair. Watch for: Bass extension not as deep as the top speakers. Overpriced. This may move around in the rankings as we get better sound samples
Buy the LG Xboom Bounce. It ranks higher for sound quality than the Marshall Stockwell III and costs less, so the other one has nothing left to offer.
