This is a Pioneer XDJ-RR. It was used at home and once at a party. It has a compact design and is easy to carry. It can be used for a wide range of purposes, from practicing at home to performing at events. I bought the controller, cables, headphones, and speakers together, so I'm selling them as a set. If you buy this, you only need a USB drive to get started. Operation has been confirmed, and it has been disinfected. I didn't plan to sell it when I first bought it, so I threw away the box. I apologize for that. I'm waiting for your comments.
