This is a DUNU DN-2000. I bought it for about 30,000 yen at the time. The sound quality is very good, and I think it's well-balanced overall. There are scratches, stains, and rust, so I'm selling it at a lower price. The items in the photos are included. I have confirmed that it works when connected to my tablet. Please note that this is a used item and is non-refundable and non-returnable (NCNR). DN2000 Earphones
