I purchased this about two years ago and have been storing it in a dark place without using it. I bought it from SHEIN for about 1700 yen. It's a wireless headphone, but it seems like it can also be used wired. I haven't taken it out of the box except for taking pictures, so I don't think there are any scratches. Please refer to the included instruction manual for how to use it (it's written in Japanese!). Please refrain from purchasing if you are concerned, as it is stored by an amateur.
