One of my more recent purchases. I enjoy using this so much. I didn’t think I’d be this happy about buying this. The Fiio Disc is multi purpose for receiving bluetooth for wired earphones or transmitting audio to wireless earphones, or even usb-dac to wired earphones. I use this everyday when I head out. This plays flacs on a micro sd card. Mainly playing my CD rips from albums I bought, but I also have some songs from anime etc stored there. The best feature of it all is the spinning album art.
