Short answer: the Vifa Helsinki. It ranks #1 of 82 large speakers by sound quality, rated 4.8/5, at $449; the Vifa Oslo ranks #8, rated 4.5/5, and costs $549, so there is not much of a tradeoff to weigh.
What the Vifa Helsinki does well: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. The tradeoff: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good.
What the Vifa Oslo does well: Extreme treble details with decent bass. The catch: Dip at 270Hz.
Buy the Vifa Helsinki. It is rated higher for sound quality than the Vifa Oslo and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
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. This one is hard to recommend generally these days: the Uboom L has 98% of the sound quality with more features and a much 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.

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, so it is the better buy if you specifically want a Vifa. This one is hard to recommend generally these days: the Uboom L has 95% of the sound quality with more features and a much cheaper price.
