This is the YAMAHA professional monitor headphone "HPH-MT8." I've used it a few times, but I own multiple headphones and haven't found much use for this one, so I'm selling it. There are no noticeable scratches or stains on the exterior, and I think it's in very good condition for a used item. All accessories are included, and I will ship it in the original box. [Accessories] ・Instruction manual ・1.2m coiled cable ・Carrying pouch ・3.0m straight cable ・6.3mm standard stereo phone plug adapter Recommended for those seeking high-resolution, flat monitoring sound. While I consider it to be in good condition, please understand that it is a used item before considering a purchase.
