Actually it sounds much better than old cassette.
The Empire Zeus IEM with seven drivers is amazing with excellent nuanced details and realistic soundstage.
Another thing is that internet connection is very stable and fast in Seoul, Korea.
While in suburb of Seattle, I had some discontinuity of music through Youtube.
This IEM almost sounds like floor standing speaker except body slamming bass.
