This is a VIVE PRO full set, originally priced at 160,000 yen. I have confirmed its operation in VRCHAT using only the items shown in the photos. Sound and tracking are working without any issues. All accessories are included. The product condition is, I believe, good. Because it's an optical system, full-body tracking and facial tracking are possible by using full-body tracking and face trackers. I own a Quest 3, but this product fits me better, and the image quality is also quite good, so I recommend it. Full-body tracking is easier than on the Quest.
