This is a set sale of items including HDMI cables, three-color cables, type B cables, adapters, and more. Individual sales are not possible. Please comment if you have any questions. I am not familiar with wiring or audio, but I will do my best to answer your questions. Some items I don't know what they are used for, and the three-color cables and the cables with square connectors have not been tested for functionality. I will strive for prompt shipping, so thank you for your understanding.
