I purchased this new from Shimamura Music eight years ago. (See the receipt in the 7th photo.) The sound quality wasn't to my liking, so I only used it a few times, and it's in very clean condition. After using it a few times, I stored it in its case in a dark place. All accessories are included. The ear pads were worn out, so I replaced them with new ones. The rubber shell of the charging cable connector has deteriorated and is sticky. Operation has been confirmed. This is a wired model.
