Me neither, but I can definitely tell the difference in audio quality between cheapies and quality ones.  

Definitely agree! I'm no audiophile, at least not like some I know, but with good headphones I can definitely hear the difference between a good flac that I have in my music library and an MP3. Or worse, the nasty compression you can hear on some songs on YouTube.

Oh for sure, cheap headphones can make things sound tinny, but decent sound comes from decent sound systems. Get a proper set of headphones and suddenly you can really hear parts of the music youd never have heard before.
