This is a VIVE PRO 2 full set. I have confirmed its operation in VRCHAT using only the items shown in the photos. There are no issues with sound, tracking, or controller use. The base stations are the 2020 model, which have been used infrequently. The product appears to be in good condition. Because it's optical, full-body tracking and facial tracking are possible by using full-body trackers and a facial tracker. I have a Quest 3, but this product fits me better and the image quality is quite good, so I recommend it. Full-body tracking is easier than on the Quest. I will offer a slight discount if you purchase trackers as well. Feel free to ask any questions.
