The Series 9 combines functional design with state-of-art technology. An adaptive shaving head comprised of four synchronized cutting elements with sonic movement, as well as a linear motor, make this the best shaver ever built by Braun. The design objective was the fusion of best ergonomics and a valuable product impression within the new Braun design language. Traditional details like the dot-textured surfaces connect with new design elements as it becomes visible with the central thumb rest.
