Short answer: the Vifa Oslo for full sound at volume, the Stockwell III for battery and features. The Oslo pairs opposing 65mm woofers with premium Kvadrat wool styling and stays full and accurate as levels climb, though it manages only an 8-hour battery with no app, EQ or water resistance. The Stockwell III runs 40+ hours, doubles as a power bank and adds IP55 protection for $249.99.
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 $299.01 less.
Buy the Marshall Stockwell III new; the Vifa Oslo is no longer sold new, so it only makes sense as a used find.
