Short answer: the JBL Xtreme 3, if you are buying new. The Vifa Oslo ranks higher than it (#8 vs #18 of 120 large speakers, 4.5/5 vs 4.3/5) but is discontinued, so only consider it used; the JBL Xtreme 3 is still sold new at $269.95.
The case for the Vifa Oslo: 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 JBL Xtreme 3 lacks. The tradeoff: Dip at 270Hz.
The JBL Xtreme 3 is the longer-running, lighter option. A loud, waterproof stereo speaker with deep bass, balanced sound and a power bank for charging devices. It is rated for 15 hours of battery against 8 for the Vifa Oslo. At 4 lbs (1.83 kg) it weighs noticeably less than the Vifa Oslo at 5.3 lbs (2.4 kg). It is rated IPX7, while the Vifa Oslo has no water resistance. The catch: Boosted bass.
Buy the JBL Xtreme 3, since the Vifa Oslo is discontinued and only worth hunting down used.
