Have you discussed this with your audiologist? Power domes require a tight fit and, if the smallest one don’t work for you, maybe the best option is to get custom molds.

Maybe try cutting off a tiny bit of the silicone ‘umbrella’ from your current domes to make them slightly smaller.

But I also agree with @OcramSagev, power domes are supposed to provide a good seal, you don’t want to compromise that!

thanks, just what i was looking for.

i asked chatgpt if they’d fit, but apparently not? does anyone have any experience with this combination

If you are close to Costco, ask for the XS sleeve for the Rexton Reach @ the hearing center. They give domes without asking your name (no fee)

I pretty sure they will fit. I’ve tried it the other way around, using Resound domes on Signia HAs and that worked just fine.

Also, if you try cutting, don’t cut length-wise. That will effectively turn your power domes into tulip domes, which have different acoustic properties.

Regarding Costco, my Costco does look up my name. When I wanted to try domes from another manufacturer, the audiologist had to authorize it. The front desk lady wasn’t allowed to just hand out different domes.

Here is a close-up from one of my cutting attempts - I wanted to achieve something in between small and medium, and I was happy with the result:

hadn’t thought of that - domes to tulips. i did try tulips; they felt very comfortable, but as you note, they sounded different.

I’m glad I was able to help !
