Nope, I haven't tried them. My last ear buds were the Audio Technica CM7ti, and my last IEMs were the UE Super.Fi 5. I only bought the IEMs for isolation purposes - and wouldn't wear them unless I absolutely needed that isolation. As far as ear buds go, I simply no longer have a need for them. All of my listening is done at home now, and thus portability and size aren't a concern for me.
If I ever need portability again, I'll probably use ear buds again unless I find myself needing isolation as well. While I don't find them as comfortable (or as good sounding) as full size circumaural headphones, I don't have a problem using them for the shorter periods that tend to make up portable use.
So yeah, I didn't mean to blow my ear bud comfort levels into a big deal, so much as point out that swbf2cheater's idealized future isn't necessarily the ideal for everybody.
