These sit in different size classes, so this is not a straight ranking comparison. The JBL Charge 5 Wifi ranks #27 of 144 medium speakers by sound quality at $250; the Marshall Stockwell III ranks #59 of 82 large speakers by sound quality at $249.99.
Why pick the JBL Charge 5 Wifi: Has Wifi. The tradeoff: Not stereo.
Why pick the Marshall Stockwell III: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. The catch: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
Buy the JBL Charge 5 Wifi ($250) for a medium speaker; the Marshall Stockwell III ($249.99) suits a large speaker instead.

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.
