I have a FiiO X3 and its the only way I can properly hear music nowadays. I'm a freelancer musician from time to time I have to spend proper time with high quality audio files as folks who transcribe music sometimes eat notes for pleasure or mistake.

Also, thanks to a friend who was into whatcd, my entire entire CD collection was ripped in a great way. I moved abroad a few years ago and I'm thankful that I could donate the less rare ones to the local library and avoid shipping a bunch of boxes to my new place.

I still purchase the majority of albums I want from bandcamp and HDtracks and having a dedicated device that can take a profissional headphone is great for my study.
