Cinematic Earbud Portrait

Create a hyper-realistic cinematic close-up portrait of a {argument name="subject" default="serious adult man"} in near-total darkness, cropped extremely tight on the right side of his face and left ear. He has short dark hair, thick brow, intense narrowed eye contact looking downward and forward, rugged skin texture, visible pores, light stubble, and a trimmed mustache. A single glossy white wireless earbud is inserted in his left ear, and one raised hand with long fingers is touching or adjusting it; count exactly 1 earbud and 1 visible hand. Use dramatic low-key lighting with a narrow hard key light from the front-left revealing skin texture, cheekbone, nose bridge, lips, ear, and fingers while the background falls to pure black. Composition should feel like a premium tech or audio advertisement: horizontal 16:9 frame, face occupying the right two-thirds, ear and hand on the left third, deep shadows, high contrast, muted natural skin tones, no text, no logos, no extra accessories. Make the image photorealistic, sharp, moody, and cinematic, with shallow depth of field and subtle specular highlights on the earbud and skin.
