The video shows a close-up of a modern, compact projector with a sleek design. The projector is white and has a fabric-like texture on its front panel. As the video progresses, the projector's lens becomes visible, and it begins to emit a blue light, indicating that it is turning on or projecting an image. The background is slightly blurred, suggesting an indoor setting with furniture like a chair and a table. The overall scene conveys a sense of technology and convenience in a home environment.
The video shows a white, rectangular speaker with a textured front panel and the 'harman kardon' logo on it, placed in a room with a blurred background. The top part of the speaker begins to lift, revealing a black area behind the front panel. As the top continues to rise, a lens and a '4K' label become visible. The lens becomes fully exposed, and a blue light starts to emit from it.
