This is a SONY HMZ-T3W head-mounted display. I purchased it used a few years ago, and it shows signs of wear. However, because I am nearsighted, I needed to use disposable contact lenses every time I used it, so I didn't use it much. I recommend the Goovis HMD for people with mild nearsightedness and no astigmatism. Regarding the condition, it had signs of use and scratches from the time I acquired it, and the pads on the forehead and back of the head are deteriorated due to aging. Considering its age, it's not in a beautiful condition. I confirmed the operation by inputting HDMI to the processor and outputting the video on the wireless HMD. I confirmed short-term battery operation, but I don't know the battery consumption. Considering its age, it may not be practical unless it's powered while in use. Everything in the images is included. The blue adapter is a third-party AC adapter for charging the battery unit. The general-purpose power cable and USB power cable are also of unknown origin.
