The DDJ-200, a Bluetooth-compatible compact DJ controller, is easily usable via USB connection. I purchased it about a year ago at a musical instrument store and used it a few times at home. The box, cables, and instruction manual are all in like-new condition. You can connect it to your phone and practice DJing. Price negotiations are possible, so please let me know your desired price. - Model Name: DDJ-200 - Bluetooth Compatibility: Yes - USB Cable Length: 1.5m - Included Accessories: USB cable, split cable Thank you for looking.
