I can't really tell from the over-exposed pics. But soft custom tips for PFE shouldn't be fitted with the IE8 unless it has a widest sound tunnel bore. You can go look at Future sonics' custom and look at the bore is huge. Dynamic needs it. Or else the sound is going to be messed up(muffled, recessed, Bad SQ). On the other hand. BA drivers IEM doesn't require as much bore width. btw, that guy has some very straight&long canals I've ever seen.
imo, canal only or around body custom tips are going to stick out just as much and performance just as same in sonic performance. just looks.
