My $150 IEM 3.5mm headphones sound better than any wireless headphones in that same price bracket.
Having a headphone jack built into my phone would be great so that I didn't need an extra dongle. I still carry around a DAP to listen to music to that way I don't have to rely on streaming services, since my last few phones haven't had a headphone jack.
Free "studio" wired headphones that came with some other equipment sound better than my $400 wireless ones. I never thought much about audio quality before then so the difference really surprised me. Now I only use wired ones.
I think part of the reason is that I like listening to acoustic music rather than pop rock edm or whatever is popular and consumer headphones tend to be bass heavy rather than going for clarity. I followed up with some studio speakers and they sound really excellent to me in comparison to the expensive consumer speakers I had before.
