the problem with universal iems is that there will always be a few kinds of ear shapes an universal iem can't fit into. It's impossible to achieve such a feat since there are so many different kinds of ear shapes. For the people that rate these highly they don't really get the flaws you get. That's why I never really bothered with iems, most don't fit in my ears .

@cs098 Too many flaws that prior Senn's didn't have and many other IEM's don't have.
It would appear I'm not the only one upset by the new design changes:
