Thread: Domes styles, open, closed, double, sizes, customs?

The fitter at Costco cut a u-shaped chunk out of the larger rear dome, and that solved the problem. They went in deep and stayed there with no issues.

    That worked fine while I waited for custom molds to come in. I has them installed a couple of days ago, and really like them. ReSound made them, molded permanently around the receivers. I'd tried acrylic molds a few years ago where you jammed the receiver into the mold, and hated them, but these are really nice.
    I assume that the clear section is the part that goes into the canal, and the brown section of the mold is the part that is visible from the outside and it fills out the ear "well", is that right?

    So it looks like the receiver sits in the brown section because I don't see any receiver in the clear section, is that right? Is that still as effective as the receiver sitting deeper into the canal? Do you lose some volume if it sits that far out from the ear canal?

    Also, if the receiver goes bad in this case, I assume that you'd have to make a new mold for a new receiver, right?

I also found the (M) double dome and tulip domes just too loose for me. So far, the (L) power domes are working out great, but if I had the time & money, I'd sure like to try out the custom-molded receiver case like you have.

    I have to ask: with these custom molds, does the receiver also sit DEEPER into your ear canal than with the typical silicone dome? Cuz that would be another huge improvement. I ask cuz I see the tiny twig at the end to enable pulling it OUT at day's end.
    I can't tell if the molds are deeper, but they are much more comfortable. And the REM test showed that the aids are performing closer to the target gain than they did with the domes.

    The clear part sits outside the canal in the bottom of the ear and anchors the mold in place.
