This is a product purchased from the Sennheiser official website. Used about 5-6 times. All parts are included. There are no visible scratches or stains. The outer box also has few scratches, but there are traces of tape being cut. (Photos are included) I will apply tape to prevent the box from opening during shipping. 【High-Quality Sound Experience】 Sennheiser headphones provide clear and balanced sound quality, allowing you to enjoy music and movies more. 【Convenient Operation】 The headphones are equipped with operation buttons for play, pause, volume adjustment, track forward, and track back, allowing for intuitive operation. 【Convenient to Carry】 The included case is made of fabric and has a lightweight and compact design.
