Smart Noise Cancelling Earbuds at Night

[Format] Professional e-commerce product main image, square 1:1, dramatic night-scene gadget advertising style with a deep starry palette. [Colors] A midnight-blue starfield sky over a jagged dark rock cliff and still water; electric blue glow rim-lights the earbuds; white headline type; a purple discount seal; a black-and-white bottom band. No frame border. [Layout] A slim white logo bar top-left. A two-line white headline stack occupies the upper left with a small grey sub-line and three white check rows beneath. The open black charging case sits on the rock at centre-right, one earbud floating above it and one standing beside. A purple circular badge overlaps the case at the right. The bottom strip is a white band with three service claims. [Subject] Glossy black wireless earbuds with short stems, blue LED accents and an open matte-black charging case with a glowing rim, set on a wet dark rock under a starry sky; one bud floats mid-air tilted, cool blue light tracing the edges, faint mist over the water behind. [Headline] White stack: "Smart Noise Cancelling, Serene Comfort" in heavy characters; sub-line "HiFi sound, rich detail" in grey. Check rows: "Bluetooth 6.0 stable connection", "Long battery life, all-day company", "Pain-free for hours, never falls off". Purple seal: "Limited-time drop, 15% off" with "15% off" prominent. Bottom white band with dark icons: "Ships in 24h", "3-year warranty", "30-day free trial". [Badges] Purple circular discount seal; small white "YOUR LOGO" tag top-left. [Mood] Cinematic and premium-tech; starry midnight blues with electric rim light, flagship-drop drama at thumbnail size.
