The “Walkman” S series boasts a textured aluminum, 7.5 mm thick body that weighs in at only 46 gram. The colorful series is equipped with Sony's own high sound quality, “Clear Audio Technology” and a maximum of 40-hours extended playback. The high-end model, with built-in noise-cancellation, sports a refined design featuring luxury hairline processing, while the model targeting young people employs a splashy design full of style and color. The seamless frame, handy size, genuine metallic texture, and easy-to-operate button layout were all implemented in order to maximize the idea of being “pleasing to hold”.
