Short answer: the Vifa Oslo for build and sound, the Soundcore Motion X600 at $150. The Oslo pairs extreme treble detail and rich bass from opposing 65mm woofers with a premium Kvadrat wool and aluminum build and 10 hours of battery, against a 270Hz dip and a cheaper, more neutral Helsinki. The X600 improves greatly on firmware 4.2.9, but its stock response is wavy, its bass is not very deep, and it needs a different EQ per volume.
The appeal of the Vifa Oslo: extreme treble detail paired with decent bass, full natural accurate sound at higher volumes, rich bass from its opposing 65mm woofers, and a premium Kvadrat wool and aluminum build with 10 hours of battery life. That’s offset by: a dip at 270Hz, and the fact that the cheaper Vifa Helsinki is generally more neutral if you specifically want a Vifa, while the Uboom L offers 95% of the sound quality for a lot less money.
Buy the Soundcore Motion X600 if the price is the priority over sound quality, or the Vifa Oslo if sound quality is the priority over the price.
Water resistance is not close: the Soundcore Motion X600 is rated at IPX7 (brief submersion), well ahead of the Vifa Oslo at no water resistance.

Soundcore Motion X600: $150 Amazon B&H Photo Video eBay
Pros: Firmware 4.2.9 is a big improvement in sound quality over previous releases. Try this Oluv EQ for the best sound quality. Measured bass extension of 52Hz (-10dB).
Cons: Stock frequency response is wavy. Use spatial mode for best sound quality. Need a different EQ for each volume step. Dip in the upper bass around 120Hz. Rising frequency response, treble a little hot. Would be ranked around #20 without the Oluv EQ. Even with the Oluv EQ the bass isn’t very deep and the sound is still a little unnatural.

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.
