Noise reduction and open fit

There are choices for venting between completely closed and completely open. I have custom molds, which are about the size of dones but made specifically for your ear canals. Mine have select-a-vent which is a big hole with a set of vent inserts of different caliber. I go with the smallest vent that doesn’t occlude and I get great results hearing in noise, and no feedback.

With your hearing loss you should get good results.
