This is a genuine adapter that came with the purchase of an iPhone. It's a convenient adapter that connects to the Lightning port of an iPhone, etc., allowing you to use wired headphones (3.5mm). I used it and then stored it. The box is missing, so this is the adapter only. I'm selling it at a low price because there's a possibility of issues due to aging. Please note that this is a used item, so please refrain from purchasing if you are sensitive to such things.
