Everything is exactly as in the product description. Shipped fast, but arrived a little late. I had to pay customs duty. The product was well packed. Inside there is the dac box, charger, 6mm to 3.5mm adapter, optical and usb cables, BT antenna, an additional front plate and user manual. Audio quality is very good for the usb input, but average for Bluetooth. The volume control also acts as input source selector.The device will remember last used input and volume.
