OnePlus Fitness Earbuds Ad

Create a square high-end fitness advertisement for [product name]. Show a muscular Black male athlete in a dark industrial gym, cropped close from thighs to head, leaning forward intensely while exercising with thick battle ropes; his face is obscured by a plain dark brown rectangular block for anonymity. He wears a black sleeveless training tank, black shorts, a thin silver chain necklace, and one visible dark wireless earbud in his right ear. His skin is sweaty and glossy, with dramatic rim lighting on his shoulders and arms, shallow depth of field, smoky gym atmosphere, blurred windows and equipment in the background, cinematic contrast, realistic commercial photography. In the lower left, place bold ad typography with 4 visible text elements: the large stacked headline “[headline text]” in white condensed athletic block letters, the smaller product line “[product line]” beneath it, a short red horizontal accent line, and the spaced-out tagline “[tagline]”. At the bottom left beneath the text, show exactly 3 product elements: 1 matte dark gray oval charging case labeled ONEPLUS and 2 floating matching earbuds angled above it. Use a premium sports-tech campaign style, dark charcoal and black palette with white typography and a small red accent, sharp product rendering, realistic sweat texture, and polished social media ad composition.
