^^ yeah they are bigger than most of IEM and don't go very deep in ear, but that are quite comfortable, i use large silicon tips and i can wear them atleast 3-4 hours if i have to, without a problem. But i tried the biflange and they are not as soft as silicon once so there was slight pain if i wore them 30-40 Min.
btw lately i have been noticing it soundstage and instrument saperation, IT IS AWESOME. Forget pinpointing, You can shoot the person playing the instrument blindfolded.
