Rio’s Carbon line of MP3 players received rave reviews upon their release. As sales rose, Rio wanted to add a high-quality, premium case to its accessory line. StudioRed┬ádesigned several concepts for new, high-end soft cases and provided Rio with materials and construction information to bring the designs to production.

Rio was so pleased with the final design, with production guided by accurate control documents from the StudioRed Design Team, that the new Premium Case was included with every Carbon model.
