This is a set of the Fiio K5 and X3 II. Includes: UGREEN RCA cable (2 male to 2 male) 2-prong to 3-prong AC adapter 64GB microSD card for the X3 Photos will be added later. No box or manual included. The items are in working condition. The K5 was not sold domestically, so it's rare. I checked the used price on Amazon recently, and it was 49,800 yen. It is currently out of stock. I have set the price based on that. Audio Player High-Resolution Audio Headphone Amplifier High Sound Quality
