“Form is nothing more than an extension of content,” David Lewis, the former chief designer at Bang & Olufsen, once remarked. Born in London in 1939, Lewis graduated from the Central School of Art and Design in 1960. A year later he moved to Denmark and began working at Bang & Olufsen. David Lewis died in 2011, leaving behind a legacy that – like his video recorder, Beovox 5000, Beovox Cona booster and Beolab 6000 active speakers – is now on display at the Museum of Modern Art in New York. These Beoplay H95 wireless headphones would surely have met with his approval. The two large rings on both sides are not there for merely ornamental purposes, by the way: the right one controls the volume, the left one the adaptive noise cancellation.
