Thank you for viewing. This is the Unique Melody Mason v3. It is a universal model, not a custom-made product. The accessories are as shown in the photos. In addition to the original cable, a 4.4mm balanced cable and a 2-pin conversion cable made by Uran Audio are included. The overall condition of the product is good.
