Short answer: the Soundcore Boom 2. It ranks #10 of 78 large speakers by sound quality at $89.99; the Marshall Stockwell III ranks #56 and costs $249.99, so there is not much of a tradeoff to weigh.
The price gap here is stark: a $249.99 premium portable against an $89.99 budget speaker. The Stockwell III offers a parametric EQ app, wall/corner compensation, and a 40+ hour power-bank-capable battery. The Soundcore Boom 2 offers app EQ, IPX7 protection, light-up passive radiators, and party-mode pairing for a fraction of the price.
Choose the Boom 2 for value: With Oluv’s or Alan Ross’s EQ applied, it delivers solid bass and party-friendly lights at less than half the Stockwell III’s price, and its rating already reflects that value.
Choose the Stockwell III for a longer battery and IP55 protection: Its 40+ hour runtime, USB-C power-bank output, and dust protection go beyond what the Boom 2 offers, if those specific features matter more than price to you.
Buy the Soundcore Boom 2. It ranks higher for sound quality than the Marshall Stockwell III and costs less, so the other one has nothing left to offer.
If battery life is a priority, the Marshall Stockwell III is rated for 40 hours versus 24 hours for the Soundcore Boom 2.

The Two Speakers In Full
Marshall Stockwell III: $249.99 Marshall eBay
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 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.

Soundcore Boom 2: $89.99 Amazon B&H Photo Video eBay
Pros: Pretty deep bass for the size. Cool lights in the side passive radiators. For the best sound quality use Oluv’s EQ or Alan Ross’s EQ. With the stock tuning, this speaker would rank around #24, due to the boosted bass and rising treble. Measured bass extension of 47Hz (-10dB).
Cons: Only a single midrange driver, so you only get stereo for the tweeters. Sound processing issues with inconsistent bass notes that disappear at low levels like the Soundcore Boom and Soundcore Boost, not great for listening at low levels. Quite bass heavy with BassUp turned on, I’d recommend turning it off. A little bit of a bright tuning in the treble, about +5db.
