I am open to price negotiations. I would appreciate it if you could keep it within a reasonable range. This is an authentic product purchased through e-earphone. The item includes only the main unit. Both the earphones and the case are in great condition with no major scratches (please check the images). I used them about once a month. I will disinfect and clean the earphones, ear pads, and case before shipping, so please rest assured. *Please note that returns and cancellations are not accepted to prevent product substitution. *The serial number in the images has been erased to protect against product substitution. This is a high-end model from Bang & Olufsen, a luxury audio brand from Northern Europe, Denmark.
