I'm not going into details about how good this player sounds. There are plenty of reviews that will explain it better than I would. So let's get to the bad stuff. The UI is straight up unusable. I didn't make this video, but it illustrates my experience/frustration with it perfectly: There is a gapless playback switch, but it doesn't work. All it does is make the gaps shorter. I'm not joking. Look it up if you don't believe me. This may not be an issue if you don't use IEMs. But with sensitive IEMs, there's a very noticeable background hiss...
