This is a digital-to-analog converter. Currently, as of January 8, 2026, it is sold on Amazon for 1699 yen. I purchased it on Amazon in December 2025. I used the converter to connect to my TV with an optical cable and output analog audio. I bought it because of its high ratings, but I couldn't get any sound, so I'm not sure if it's due to poor operation or incompatibility. Therefore, I am selling it at a low price. The items for sale are the converter unit, a USB cable, an optical cable, and the instruction manual. I will ship it in the original box, which will then be placed in another box.
