黑五 70% 折扣耳机横幅

Horizontal banner advertisement design, 16:9. Left half shows a giant percentage figure "70%" in heavy bold black typography on a vibrant orange background, with the smaller word "OFF" stacked underneath. Right half is a deep matte black background featuring a single floating over-ear headphone product silhouette with subtle rim lighting. A thin yellow horizontal divider runs across the middle. Bottom right shows a small clean white CTA button reading "Shop Now". No brand logo, no real brand name, no watermark. Crisp e-commerce promotional ad design, photorealistic product, sharp typography.
