Short answer: the Bose SoundLink Max, if you are buying new. The Vifa Oslo ranks higher than it (#8 vs #17 of 120 large speakers, 4.5/5 vs 4.3/5) but is discontinued, so only consider it used; the Bose SoundLink Max is still sold new at $399.
What the Vifa Oslo does well: A premium wool covered portable with full, natural, highly accurate sound and rich bass, now discontinued but worth buying used. It supports aptX Bluetooth, which the Bose SoundLink Max lacks. Watch for: Dip at 270Hz.
The Bose SoundLink Max is the longer-running, tougher pick. A rugged waterproof speaker with deep bass, a very long real world battery and a port that charges your phone. It is rated for 20 hours of battery against 8 for the Vifa Oslo. It is rated IP67, while the Vifa Oslo has no water resistance. The tradeoff: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange.
Buy the Bose SoundLink Max new; the Vifa Oslo is no longer sold new, so it only makes sense as a used find.
