Premium Black Headphones Product Photo

Create a clean premium product photograph of {argument name="product" default="black Sennheiser over-ear wireless headphones"} standing upright at a three-quarter angle on a seamless light gray studio background. The headphones have a thick padded black leather headband with subtle stitching, soft oval memory-foam ear cushions, matte black yokes and hinges, and large circular earcups with a satin radial-brushed finish. Show exactly two earcups, one in front and one partially behind; the front earcup displays small centered white text reading {argument name="brand text" default="SENNHEISER"}, and the upper hinge plate shows the stylized Sennheiser logo. Include small visible details: one USB-C port on the lower left earcup, tiny microphone/indicator holes, and realistic seams where the pads meet the cups. Use controlled studio lighting with soft highlights on the black leather and metal, a faint shadow beneath the headphones, shallow but crisp product focus, no hands, no props, no packaging, no extra text, no watermark. Composition should be vertical 3:4, centered, minimal, high-end e-commerce style, photorealistic, ultra-detailed, with a subtle gradient from pale gray to white in the background.
