HiFi in the New Age

LS50 Wireless Nocturne was produced in collaboration with the inspirational Dutch designer Marcel Wanders. His concept of bringing a human touch back to design is reflected in the graphics adorning the driver and baffle of Nocturne. Look closely, and the artform of music is subtly celebrated throughout, with musical notes, bars and ornamentations featuring. Turn off the lights, and Luminova paint brings life to the darkness.
