The classic boxy design remains, the sound and performance has been magnified thanks to True390 technology. Meet the Bang & Olufsen Beolit 15, a dual-amp powered system good for 240 watts of aural awesomeness. Dual 4-inch passive radiators ensure an energized bass while the Bluetooth 4.0 eliminates the need for WiFi. The battery will last a whole day and you can choose from natural champagne, Polar blue or Shada Rosa accents.
