This is an aged product. I purchased it used and have broken it in for over 100 hours. There are no operational issues. Included accessories are an unbalanced cable and a dedicated case. The price is based on e-earphone's C rank. 【Condition】 The headband has damage such as tears and dents. There is no hydrolysis. The material of the black leather part of the headband has softened due to aging, and it will probably tear easily, so those who are concerned should put a cover on it. There is no deterioration or hydrolysis on the ear pads. I always used covers on both.
