I bought it new but haven't had a chance to use it, so I've been storing it. It's unused, but it has been stored at home, so If you are sensitive to details or are looking for perfection, please refrain from purchasing. #Headphones #WiredAndWireless #Commuting #School #Music #Movies #Games If anyone is interested, feel free to comment.
