I'm definitely not an audiophile and I listen mostly to voice podcasts, such as NPR programming. Besides sound quality, is there any real advantage on these over low-end, detachable-cable Shure?
I'd check the level of noise isolation, since that is likely to be the main difference. Custom in-ear with wrapped tips (Comply) seems to be the best you can get (roughly -26 dB). They aren't total isolation -- I have fairly good hearing and can still hear people talking next to me if there's nothing playing through them -- but put any kind of sound through them at almost any volume and I might as well be alone.
