The Apple Vision Pro comes in a very, very large box. According to MacRumors, the packaging has the typical design of many other Apple devices, only much larger. The image you can see at the link below is said to be from an Apple employee training video. Although the exact size is not known, it seems to be more similar to the packaging of a Playstation 5 than the compact box of a Meta Quest 3. The reason for the size is probably the included accessories. The Apple Vision Pro comes with a battery pack, a 30W USB-C power adapter & USB-C charging cable, a headband and more.
