As someone who doesn't care much about audio quality I can try to explain. Part of it I suppose is that even though I like music, I don't _like_ like music as some people seem to do, like music is their life and a huge spare time interest. I just like to listen to some stuff sometimes, but sometimes I can go a week without listening to my Spotify account or the radio. Another part of it is that I feel like I get most of the benefit already with "regular" ear-phones, I don't need super duper audio quality to enjoy a song. The song is in your brain anyway, and your perceptions are not as perfect as you think. Think of it like suspension of disbelief in a video game. I used to play games with really shitty graphics, but that didn't affect the way I enjoyed the game because my brain fills in the rest.
