Perfect synergy of fashion, fitness and technology

“When we took on the design of Active Style headphones, we kept three themes in mind: fashion, fitness, and technology. By technology, we meant compelling structural design, performance and reliability .We’re lucky that high- tech materials today enable very polished styling and are extremely high-performance when put in use. We were impressed by the attention to materials and details and sought to express the same thing in headphone design.”

Jun Komiyama, Sony Corporation Creative Centre Producer

Beauty inside and out

“Active Style is an original set of products, so we tried a new style of packaging. Clamshells are expected to showcase the entire product. But this time, we defied convention by concealing half of the headphones. We tease people by revealing the most attractive portions of each model in a cutaway window. It’s an effect that works well with symmetrical products such as these. I think we succeeded in reworking traditional clamshell packaging while letting the products, which are unmistakable examples of Sony style, play the starring role.”

Natsuki Kimura, Sony Corporation Creative Centre Designer

One design, five models.

“For headphones worn during fitness activities, our first task is ensuring a good fit. They must not fall off easily, even if users move around a lot. But enlarging the pads or applying too much pressure on users’ ears is hardly an elegant solution. From the standpoint of design, structurally simple headphones that gently envelop your ears and resist falling off would be desirable. Surprisingly, there were no precedents for the ideal shape. After trying several approaches, we decided on five models of Active Style headphones.”

Yasuo Yuyama, Sony Corporation Creative Centre Senior Producer

Music and fitness. It’s your style.

“For designers, headphones are very satisfying products to work on. Not many things in industrial design are so close to users, physically. They’re virtually extensions of the user’s body. These kinds of products can’t be described by specifications alone. We can invite users to find their own unique style through design, and that’s enjoyable. It’s the greatest compliment to us if users refuse to part with their favourite headphones, even after replacing their audio player.”
