VITURE black smart glasses. - Brand: VITURE - Color: Black - Accessories: Charging cable, 3 types of height adjustment I used them about 5-6 times, but the display stopped working. I suspect it's an issue with compatibility with my smartphone, but the error code indicates a cable malfunction, so I think it should work if the cable is replaced. Please purchase only if you understand this. Immediate purchase and questions in the comments are welcome. Thank you for looking.
