I recently learnt about Hi-fi audio and the audiophile community in general. Felt like I should try out something entry-level in this spectrum. I bought the following two things IEM and DAC

However, I feel I’m unable to truly appreciate the difference. Yes it sounds ‘better’ in some vague sense of the word but I can’t articulate how the sound is different from regular headphones (I have the sony XM4 and other crappy earphones).

I’d really appreciate it if someone gave me a way to really start appreciating and enjoying these devices. Maybe a popular song that amplifies the difference? Or maybe a specific detail that I should look for that I’ll find in Hi-fi gear but not in regular headphones?

Looks like I still have no clue what it means to be an audiophile :)

Please help.
