Purchased from the e☆イヤホン headphone specialty store on February 3rd of this year. Used indoors about 5 times. I used it very carefully with ear covers, so I think it's a beautiful item with no scratches or stains. Please check the images. The main unit, cable, plug, case, box, instruction manual, warranty, receipt, etc., all included items are complete. The warranty is for 2 years and almost all of it remains.
