Smart Earbuds Sales Landing Page

I need a single-page e-commerce layout that drives immediate purchases of my new smart earbuds. The page must look modern and sleek, presenting the product as premium yet accessible on any device.

Key content areas I want featured:
• Eye-catching hero section with a clear “Buy Now” CTA
• Concise technical specifications displayed in an easy-scan format
• Prominent pricing with room for limited-time discount banners or coupon code fields
• Secure checkout button that stays visible as users scroll

Smooth micro-interactions, fast load times and a layout built for conversion are critical. I’m open to Shopify, WooCommerce, custom HTML/CSS/JavaScript, or another lightweight stack—as long as you keep the code clean and mobile-first.

Please include:
• A hand-off file (Figma, XD or similar) plus the final responsive HTML/CSS/JS package or theme files
• Instructions so I can update specs, images and discount amounts without touching code
• Any assets or licenses used

Final approval hinges on passing Google Lighthouse performance scores and a quick sandbox purchase test.
