Excellent condition Xreal Air Nreal Air NR-7100RGL AR smart glasses. This is the Nreal Air before the name change, model number NR-7100RGL. You can connect it to your smartphone with a cable and mirror YouTube to watch it like a theater, or use AR functions. However, the smartphones that can use AR are limited, so please refer to the website. Even if your smartphone can't use AR, you can still mirror the screen and watch on a large screen theater. It was a gift, and I haven't used it much. I watched a movie once and watched some YouTube in my room, so I haven't used it much. The set includes the glasses, dedicated cable, and case. The box is not included. Please refer to each website for detailed explanations.
