A single continuous 15-second vertical phone-camera UGC advertisement demonstration, using the exact fictional adult creator and terracotta over-ear headphones in the starting frame. Preserve his face, curly hair, sage overshirt, charcoal tee, window-lit desk, and exact headset color, oval cup geometry, curved yokes, cushions, and headband. The headphones stay correctly worn over both ears throughout. 0–3 seconds: looking at the camera, he gently adjusts the outer earcup once with the fingertips already touching it, saying "Too many tabs open?" 3–7 seconds: he naturally lowers that hand to the desk and glances briefly at the laptop, saying "Try a little desk reset. Headphones on, playlist ready." 7–12 seconds: a small relaxed head nod to the listening rhythm; he looks back to camera and says "Pick one task, and find your rhythm." 12–15 seconds: he looks down and begins a small natural typing movement, still visibly wearing and listening through the same headphones. Spoken script exactly: "Too many tabs open? Try a little desk reset. Headphones on, playlist ready. Pick one task, and find your rhythm." Natural conversational adult male English voice, clear synchronized speech, brief pauses, subtle quiet instrumental pulse beneath the voice and normal room ambience. One fixed phone camera with barely perceptible handheld breathing; no cuts, no montage, no zoom or spin. Product and face stay readable. No subtitles, logos, generated app UI, new people, extra fingers, morphing or duplicate headphones. This is a fictional AI-generated advertisement concept, not a customer testimonial or a claim of tested headphone performance.
