The Ety larger sized tips (I need the big ones) are more cushy and spongy kind of feel:
So they fit me different. Plus, the ER4Ps have a long, thin narrow shaft on the end. So I get a different insertion depth than with some other headphones. Don't know if that would help you or not.
Ah, they are different. Shame they wouldn't fit on the Hifimans, the opening is far too small.
What would the angle change, and how would that potentially help with my problem?
