I remember now why I never liked earphones -- I can't wear them properly. The left one will fit just fine, but the right one will never fit properly. So I have to keep shoving it in or else it'll come loose eventually. The result is an aching right ear, raw around the canal opening.
So stupid, that my right ear is shaped ever so slightly differently from my left.
I knew I should've bought headphones. Maybe one of those big ones that you see at the listening stations at HMV or Tower. Dammit.
