Short answer: the Vifa Oslo for better sound quality, the Marshall Stockwell III for the lower price. The Vifa Oslo ranks #8 of 78 large speakers at $549. The Marshall Stockwell III ranks #56 at $249.99, $299.01 cheaper.
This pits Marshall’s mid-priced portable against a premium fabric-and-aluminum design built around full, natural sound. The Stockwell III offers a parametric EQ app, wall/corner compensation, and a 40+ hour power-bank-capable battery for $249.99. The Vifa Oslo offers rich bass from opposing 65mm woofers and premium Kvadrat wool styling, with only an 8-hour battery, no app or EQ, and no water resistance, for $549.
Choose the Vifa Oslo for natural sound at higher volumes: Its opposing-woofer design delivers full, accurate sound as levels climb, in a genuinely premium cabinet - though it’s worth noting the cheaper Vifa Helsinki is generally considered the more neutral choice within Vifa’s own lineup.
Choose the Stockwell III for battery life and features at a fraction of the price: A 40+ hour battery that doubles as a power bank, a parametric EQ app, and IP55 protection cover practical needs the Oslo doesn’t, for $300 less.
Buy the Marshall Stockwell III if the price matters more than sound quality. Buy the Vifa Oslo if sound quality matters more than the price.
If battery life is a priority, the Marshall Stockwell III is rated for 40 hours versus 8 hours for the Vifa Oslo.
Water resistance is not close: the Marshall Stockwell III is rated at IP55 (water jets), well ahead of the Vifa Oslo at no water resistance.

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.

Vifa Oslo: $549.00 Amazon eBay
Pros: Extreme treble details with decent bass. Full, natural, accurate sound at higher volumes. Rich, full bass from opposing 65mm woofers. Premium Kvadrat wool fabric with aluminum handle. 10 hour battery life. Measured bass extension of 50Hz (-10dB).
Cons: Dip at 270hz. The Vifa Helsinki is cheaper and generally has a more neutral frequency response, I’d highly recommend getting one of those instead if you specifically want a Vifa. Not sure I can recommend this one generally these days, the Uboom L has 95% of the sound quality with more features and a way cheaper price.
