Scene: Dark gradient background, cool white rim lighting, minimal floating stage. Characters: Matte black wireless headphones suspended at center. Action: A slow 180-degree orbit reveals cushion detail and brushed metal hinges; the headphones rotate gently as if weightless, subtle reflections shifting across the matte finish. Camera: Smooth horizontal orbit at constant speed, slight upward tilt at the midpoint, ending on a head-on hero frame. Audio & Style: Sub-bass swell synced to rotation, single bell tap on hero frame, premium product launch grade.
Negative: visible rig, motion blur smearing logo, text morphing, watermark.
