Short answer: the Vifa Oslo. It ranks #8 of 82 large speakers by sound quality, rated 4.5/5, at $549. The JBL Xtreme 3 ranks #18, rated 4.3/5, at $329.95, $219.05 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Vifa Oslo: Extreme treble details with decent bass. The catch: Dip at 270Hz.
The case for the JBL Xtreme 3: Better treble and deeper bass than the Xtreme 2. The tradeoff: Boosted bass.
Buy the Vifa Oslo. It is rated higher for sound quality, and the $219.05 saving on the JBL Xtreme 3 is not enough to make up the difference.
If battery life is a priority, the JBL Xtreme 3 is rated for 15 hours versus 8 hours for the Vifa Oslo.
Water resistance is not close: the JBL Xtreme 3 is rated at IPX7 (brief submersion), well ahead of the Vifa Oslo at no water resistance.

The Two Speakers In Full
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.
