FiiO K9 PRO ESS High-Resolution Headphone Amplifier & DAC Purchased used. All accessories are shown in the images: Main unit, AC power cable, USB cable, 6.3mm to 3.5mm adapter, Bluetooth antenna, replacement fuse, vertical stand, stickers, and box. It appears the quick start guide and the XLR headphone jack cover are missing. The rubber feet are already attached. It was working without any problems. I don't think there are any major scratches or stains, but please understand that it is used and may show signs of wear. It is also listed on other apps, so it may be sold out depending on the timing. Thank you.
