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.
