Premium Noise-Cancelling Headphones with Free Case

[Format] Professional e-commerce product main image, square 1:1, glossy tech-retail style with a luminous gradient and feature pills. [Colors] Background is a pale lavender-to-periwinkle gradient (#cfd0ee to #b8c4f0) with a soft glowing swirl behind the product. Accents are deep purple pills, a golden-yellow offer badge, black and white type. No frame border. [Layout] A small circular placeholder badge and "YOUR LOGO" text sit top-left. The left half stacks the two-line headline, three purple feature pills, and a yellow offer box; the right half is filled by the large headphone. A black strip and a white bar run across the bottom with price and promo text. [Subject] Right: premium over-ear headphones in three-quarter view, black leather-textured headband and ear cushions, chrome-plated yokes and adjusters, and iridescent blue-purple outer shells catching a rainbow reflection. Slight tilt toward the viewer with a gentle glow. Bottom-left of the offer box shows a small black zippered headphone carrying case. [Headline] Left, two stacked lines of very heavy deep-purple display caps: "Multi-layer noise cancelling" and "Comfortable listening". Three purple rounded pills beneath in white bold: "HD mic, crystal-clear calls", "Fast charging, no battery anxiety", and "Ergonomic fit for every head". [Badges] A yellow rounded offer card reads "First 100 orders receive a free headphone storage case" beside the case image. The bottom black strip carries white text "15-day free trial | 24h express dispatch"; a purple price block shows "Your price $299" with a large white "299"; the white bar below reads "Order today and save $122" in bold dark caps. [Mood] Sleek, premium and promo-packed; pastel tech glow with deep purple authority and a burst of yellow urgency.
