Short answer: the Marshall Stockwell III. It ranks #59 of 82 large speakers by sound quality (rated 3.0/5); the Orange Box ranks #71 (rated 2.5/5).
Why pick the Marshall Stockwell III: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
Why pick the Orange Box: 50W RMS output power, IPX7 waterproof, 15-hour battery life, guitar amp-inspired vintage design, 102mm woofer with dual tweeters, Bluetooth 5.0, AUX input, TWS pairing, built-in microphone, solid wood construction. The tradeoff: Pathetic bass extension, port noise, hollow sounding.
Buy the Marshall Stockwell III. It is rated higher for sound quality than the Orange Box.

The Two Speakers In Full
Marshall Stockwell III: $249.99 Marshall eBay
Older model: the Marshall Stockwell II (rated 4.5/5).
Pros: 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.
Cons: 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 II 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.
