Domes Info

Wanting to get some feedback.

I've been testing the Oticon Dual Connects. I like them a lot but I'm trying to get the most out of them. There are four different types of domes: open, plus, power, and RITE mold. So far I've tried the open and plus; I'm liking the plus better for many reasons.

Can anyone give me some information on the power dome; what it's like, best applications, or any other insights. How it works, and why it's called a power dome?

Any feedback would be great.
