I have KS 7’s with tulip domes. To insert them (esp. the left) I have to push somewhat hard. Also, both ears itch.
I tried tulip domes. I have small ear canals. The receiver end of the ReSound tulip domes that I tried had a hard oblong shape to hold the dome “petals” (flaps) flared out. So I think it was mostly that that made the tulips uncomfortable for me to wear. The “one-size-fits-all” large but compressible, overlapping flaps/petals probably did not help, either. For me, one ear canal is larger than the other so it’s more comfortable to wear domes that are unmatched in size. As far as I can tell, that doesn’t cause a different hearing sensation in each ear. So I’m now wearing a small power dome in one ear, a medium-sized one in the other. I wanted a fair amount of occlusion.
