What is your hearing sensitivity at low frequencies between 250-1000 Hz? What is the worst number for high frequencies (4-6K Hz)?
I had the same issue during my first trials and my Audi had to redo the mold for 3 times. I found the double domes would snug better all day till I go home and have dinner. Yes, I have occlusion and it’s getting worse if I catch cold but sounds perspective is good most of the day. Due to COVID, Didn’t have the chance to visit my Audi lately (since January) . I guess it’s time for a check up.
I am using the Opn S1 miniRITE for about 1 year now. Because of the curving of my ear canals molds were made. The first set of molds was replaced because they were slipping out very easy, and because the receivers were being covered by the wall of the canal - if I pulled the molds slightly out of the canal, hearing would improve immediately but the hearing aids would slip out. I have a turn in the right ear canal of about 60-70 degrees. To a much lesser extent I have the same issue in my left ear. My audi took new casts of both canals and had the right side mold made slightly longer and both sides individually shaped such that they would not get covered by the walls. The air vents on each side were differently located to keep the wall from covering the receiver. Third, to prevent them from sliding out, the molds were extended on the outside to sit firmer in the concha. The attached pictures might give you an idea of how they are shaped. The costs for the molds were included in the purchase price of the hearing aids.

Here are my KS9’s with DIY silicone earmolds and a picture of one in my ear.
Per the instructions I use a dome on the receiver to protect the outlet tube when doing the molding. I roll the mixed silicone out into a long thin rod and then wind it around the receiver before putting it in my ear.
I had bad occlusion effects with my left ear and mild effects in my right ear. The grooves you see in the photo are vents that I made to fix the occlusion effects. I used a razor blade to cut the grooves. The instructions suggested using a small file for this.
I paid something like $30 for the silicone kit and have made 5 or 6 sets of earmolds for various reasons. I probably have enough left for several more sets if needed.

I just received my custom slim tips having 1.5mm vent.
The fitting is so comfortable. No feedback atall.
just that after 3 hours or so, I feel its bit lose…hence have to remove them…wipe the tips with tissue/cloth, clean my canals with q-tips and then it fits well again for the next few hours.
I guess my ears are bit oily, hence after few hours the tips seems to slip a bit.
This seems to be an excellent solution. Thanks for sharing.
I would love to try this option.
I tried to look for this seller online, but no luck.
Incase you find any seller, please forward me the link so I can order.
I had this issue when I wore 2 x HAs.
My left would get wet all the time, once dried, the ear mould would fit really well again.
I don’t wear a HA in my right ear now but my right ear never got wet. It was very odd.
Thanks a lot.
I have requested them that I will pay for delivery cost & if they can arrange delivery in Dubai, UAE.
Lets hope for the best.
I received their reply today.
Unfortunately they do not deliver their product outside the USA.
If you can locate a source for the silicone then you don’t really need to order from the American supplier. The kit that he sells has the silicone and the instructions. That’s all there is. Maybe one of the members on the forum can tell you what kind of silicone you need. I suspect it’s the same thing used for ear impressions which they probably do most everywhere in the world.
I think that would work.
Found this on Amazon. Don’t know if it will work in your location.
That is a mirror of a problem I have. I have 2 Oticon made RIC moulds, they are great but the left one is a little loose and gives feedback when eating. I had them made using the “Otoscan” method. I’m thinking of saving up and have 2 made with silicone with canal locks.
I have since then had acrylic full skeleton ear molds made for my ears and I no longer have any problem with my ear mold slipping or with feedback.

I too have acrylic skeleton moulds and have no issues with feedback etc. I don’t have vents.
Great write up, exactly what I intend getting. Power moulds are great but useless if their performance is hindered by poor fitting or excess movement.
In my opinion it is all down to the technician who uses the syringe and solution to make your impression for the mold.
Bad impression…bad mold.
