A sculptural product-presentation concept for a fictional headphone brand. A real-time Three.js model includes a shaped headband, metallic earcups, cushions and small hardware details. Visitors can rotate the model and switch between Champagne, Obsidian and Porcelain finishes. A separate collection-manager demo combines the same live 3D preview with editable product-name and description fields. The responsive layout includes motion controls, reduced-motion support and a WebGL fallback message. Built with HTML, CSS, JavaScript and Three.js. Self-initiated demo / fictional brand; no client results. This is a product-design study, not a store: no checkout, stock management, authentication or backend is connected, and editor changes are not saved.
