Short answer: the Vifa Helsinki if sound quality matters most, the Marshall Stockwell III if price matters most. The Vifa Helsinki ranks #1 of 78 large speakers at $449. The Marshall Stockwell III ranks #56 at $249.99, $199.01 cheaper.
This pits Marshall’s feature-heavy Stockwell III against the Vifa Helsinki, widely regarded as one of the best-sounding battery speakers for midrange and treble accuracy. The Stockwell III offers a parametric EQ app, wall/corner compensation, a 40+ hour battery that doubles as a power bank, and IP55 protection for $249.99. The Vifa Helsinki offers class-leading mid/treble accuracy from its shared-woofer stereo array, though only an 8-hour battery, a broken official app, and no water resistance, for $449.
Choose the Vifa Helsinki for sound quality that’s still considered a class leader: Despite lacking EQ, a working app, or splash protection, its midrange and treble are consistently ranked above other battery speakers in this class.
Choose the Stockwell III for a far more complete feature set at a lower price: Its 40+ hour battery, IP55 protection, and USB-C power-bank output cover practical needs the Helsinki doesn’t address, at $200 less.
Buy the Marshall Stockwell III if the price matters more than sound quality. Buy the Vifa Helsinki if sound quality matters more than the price.
Battery life favors the Marshall Stockwell III: rated for 40 hours against 8 hours for the Vifa Helsinki.
There is a real gap in water resistance: the Marshall Stockwell III at IP55 (water jets) against the Vifa Helsinki, which has 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 Helsinki: $449.00 Amazon eBay
Pros: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. Measured bass extension of 48Hz (-10dB).
Cons: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good. Not sure I can recommend this one generally these days, the Uboom L has 98% of the sound quality with more features and a way cheaper price. There are mentions that the 2022 “new” version of this speaker doesn’t sound as good as Vifa was purchased by a Chinese company and laid off all the great sound engineers in the Austria office.
