In the video, a person is holding a large black speaker. The speaker is being shaken back and forth, and the person is looking at it. The speaker appears to be quite large and heavy, and the person seems to be examining it closely. The background is not clearly visible, but it appears to be an indoor setting. The person's actions suggest that they may be testing the speaker's sound quality or checking its durability. The video does not provide any additional context or information about the person or the location.
