Manufacturer: 1Mii Product: DS-200Pro Specifications: LDAC Hi-Res Audio Built-in Bluetooth, DAC I used this for a while after purchasing it and then stored it. I have confirmed its operation before listing it, and it works without any problems. I had it connected to my home audio system, and the sound quality is satisfactory. It costs over 12,000 yen when new. The protective film is still attached, so it's starting to peel a little, but there are no major scratches, and the condition is good. The box is also dirty, so please understand that it is a used item. Please judge the condition from the photos. Please refrain from purchasing if you are sensitive to such things. The accessories are those shown in the photos. All accessories are included. The original box will be folded and included. It will be shipped via Takkyubin Compact.
