This is a listing for the Beats Studio Buds, including the main unit and the left and right earbuds. I purchased these used, but I am selling them as junk because I cannot reset the main unit or connect it to a smartphone. ・The charging light comes on. ・Both the main unit and the earbuds look very clean with no scratches or stains. ・The display shows "Please connect to your smartphone," but pressing the button on the earbud for 5 seconds does not connect it. ・A long press of 15 seconds does not reset it. ・The light comes on when the button is pressed, so the button itself does not seem to be faulty. ・I cannot connect to a smartphone, so I have not been able to confirm the operation of the earbuds. This is a junk item, so please understand that it is non-refundable and non-returnable.
