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

  1. Default Domes styles, open, closed, double, sizes, customs?

    New to HA's, and having trouble adapting. Signia Pure 7px's, about 3-4 weeks ago.

    Going fairly well EXCEPT for the in-ear receivers. (Why do they call what is to the rest of the world a speaker a receiver?)

    I first tried 12/10mm double domes not vented at all. Drove me nuts! Felt completely stuffed up, really bad own voice, and they itched till I couldn't stand them. With enough determination, I could keep them in about 2 hours max at a time.

    Next tried 6mm open. Way too small, but no problem wearing them long term. Comfortable, but spent all day pushing them back in due to too small.

    Next tried 10mm open. Again, comfortable, sound good, but still spending all my time pushing them back into position.

    I was advised by a friend who has had HA's since childhood that customs are the only way to go for comfort. I believe she has open, customs?

    I don't have 12mm's to try, but I suspect that they will just work their way out like the smaller ones, and be uncomfortable as well. I seem to have tapered ear canals, without much for the domes to grab on to.

    I have my next apt with Audi Friday, and if customs are the better way to go, I'd like to get that done and not drag this experiment out any longer. Cost is not nearly as important to me as something I can wear!

    Any advice appreciated!

    Did you pick out what you want to try or did the audi recommend these dome types for you? I'm surprised that your audi lets you try open domes with your level of loss. I can understand why he/she started you out with a power dome (which I believe the double domes are called). But I can see how you'd hate them with the occlusion problem. The itching may or may not go away, depends on whether your ear canals can adapt to the silicone or not.

    I wonder why the audi didn't put you on closed single bass dome with maybe a single vent hole or double vent hole? That was the first natural choice my audi put me on, a closed single bass dome with a single vent hole. After trying out a couple of sizes to find the right one, that was pretty much it. The occlusion is still there but only slightly (as compared to an power dome), but it kept to a minimum and I got used to it real fast. I tried the same dome but with 2 vent holes (the vent holes are tiny compared to the vents in the open domes), but it caused a slight wheezing feedback when I put my headphones on, so I went back to the single vent hole bass dome.

    I'd recommend you try that next (single vent hole closed bass dome). If still a little occluded, try the double vent hole next.

    If the bass dome still doesn't help, then custom molds would be my last resort. They're not cheap, and they'd feel more occluded, although they can put some vent hole in there to help with the occlusion. If your ear canal is truly very asymmetrical then custom molds may be your only option. At least they'd help out a lot with feedback control as long as you don't have too many vent holes on it.

    you hear well enough with open domes compared to the close ones? molds are pretty much a must, and they aren't too expensive, but surprised that the open domes sound good to you....

    All the kool kids have open domes and iPhones.
    Remember.. “It's more important to look good than to hear good.

    Yes, looking Kool is the most important thing.
    Actually hearing what's going on around you isn't necessary any more.
    Talking and listening aren't Kool (or needed) in today's social media society!
    That's just for old f***s.
    Plug buds in your ears, and text. You'll look Kool, and no one cares if you can hear.

    ^well anyway, I would have imagines since you need alot of highs and mids (frequencies) a closed mold might be more suited, you might wanna check again before deciding for a half shell or something similiar....

    Thanks to all: I appreciate the inputs. It'll take some more trials to find what works, and at the same time, what my ears can tolerate!


    I did find an article on "One of the great mysteries of audiology." Why the HA industry calls the sound generator a receiver:

    Not useful information, but interesting entertainment.

    Bob,

    I've worn hearing aids for about 10 or 15 years. It took a while, but I can go for 6 or 8 hours before I start feeling clogged up and take them out. I never did well with domes. I have tried a few custom molds, and am most happy with the open mold from Westone (model 12). They are not as invisible as domes, but they feel and sound a lot better.

    Based on your advice to Bob, now I'm curious whether I shouldn't have open domes. (I currently do).

    If you're happy with open dome then that's all that matters. But it wouldn't hurt to try the closed bass dome with single or double vent holes just to see if maybe you'll be even
    happier with them. Domes are cheap to try out so I think it'd definitely be worth a try. But you'll need to see your audi not just to get the domes but to also have them change your programming profile to match with the right dome type.
