Hi all, I have a perfectly functional etymotic er6i. Issue is it's original flange has worn out. I bough the replacement flange from etymotic but the replacement are much smaller then original and so not provide a good for and comfortably fit at all. Are there any other options ? For example - will any of the shure triple sleeve flange work with er6i ? In worst case I may switch to foam although it's not my first preference. I see mention in Internet that shure black foam olive sleeve works with er6i. Anyone here got any experience with it ? Thanks for your comments in advance.
