These are collaboration headphones produced in limited quantities, making them difficult to obtain now. I purchased them used and only tried them once. While not very noticeable, there are many scratches and signs of use as a used item. Please be aware of this if you are sensitive to such things. They worked without any problems. Please check the photos for the included accessories. The cable is 3.5mm. I am not able to offer significant price reductions. Please understand that I will not respond to comments that I believe have not read the product description.
