For sale is an authentic Harman Kardon Onyx Mini Bluetooth Speaker Black in working condition. Comes with USB power cable. Item was tested, powered on and connected to Bluetooth without issue, as shown in the last picture. Item is in decent overall shape with some wear from use, including scuffs, scratches, and marks. Battery life has not been fully tested, so I do not know how long it will last on a full charge. Pictures are of the actual item you will receive.
