I'm trying to improve isolation on my ECCI PR401s. I have a couple of leftover Comply T-400s (for my now broken Nuforce NE-7M) but they don't seem to fit the PR401 nozzles. Can anyone recommend an appropriate size/model for the ECCI PR401s?
Secondly, I like the seal and fit of the Comply foams but was never really in love with how they seemed to deaden the highs. Are the new foams any better? I don't want to lose whatever sparkle is in the IEM's signature.
