Thanks to Mago for making me aware of these- and in quotes below I cite his prior post.
As I have struggled to get my Resound Double domes to fit me comfortably, I have experimented with the Starkey Occluded Comfort Domes. I do feel they fit securely on my Resound Forte receivers.
These Starkey Comfort Domes have a clever 3 dimensional design that incorporate some of the the attributes of custom molds into domes. They have something of a globe shape and fit over an area in your ear canal (as does a mold) rather than at just the highest point of pressure as does a common double dome.
The fit of these appears to be more critical- and Starkey seems to acknowledge this as these comfort domes are available in 5,6,7,9, & 11 MM sizes (unfortunately no 8 or 10 mm)
As Starkey is the only large US based Hearing Aid company, the online source I could find for these was based in the UK (go figure) . I ordered the 9MM and found them to be VERY comfortable, but ever slightly not snug enough, as I got a lot of feedback. They were so close to fitting me that I knew the size I was truly going to need was a 10 MM size which is not offered.
I ordered the 11mm ones and received them yesterday- and as I feared they are a bit too tight. I have stuffed them into my ears and am trying them at work today- but right now I am afraid I am going to conclude that the 9 mm are too small, and the 11 mm are too big.
By the end of the day I fear I will be back my homemade solution of punching holes is the sides of my Resound Double Domes -still trying to find that elusive comfortable fit.
“Starkey makes Comfort Buds occlude. These domes have 2 tiny holes, and come in a variety of sizes. I wear them on OPN1 P100 receivers. After years of trial & error - slitting, cutting, hole punching, and trying every dome available, my Audi gave me these to try. The absolute best, most physically comfortable solution to date. If the teeny holes get plugged or turn and hit my canal, I get that stopped up feeling. The small amount of venting is perfect for me and consistent from dome to dome. I also wash them daily, unplug the holes with the black plastic wire tool to keep the vents open.”
