    Oh, and at Costco (with a hearing aid fitter, not an audiologist), I found that I very much liked the tulip dome in my right ear using Resound Cala 8's (Costco-branded Linx2). The fitter thought I'd need the closed domes but it made me feel as if I were in a bucket or had my finger in my ear every time I spoke. The tulip dome sounded much more natural to me. I got an open dome for my less-lousy left ear.

    OP, it wouldn't hurt to post your audiogram. You could copy the table below to your signature and fill in the blanks from your audiogram.

    R ## ## ## ## ## ## ## ## ## ##
    L
    ## ## ## ## ## ## ## ## ## ##

    Your right ear is shown in O's and red (on a color printout) on the audiogram and your left ear in X's and blue. There may well be other markings, but those are the basics.

    The OP ain't been back since 12/14/16 so I suspect just another bullshit artist!

    Now the tread has been hijacked into another Costco thread!

    I started with closed domes and they felt like fingers in the ears. Open felt better. I'm not sure if that is because they look more flexible. Closed had somewhat of a tunnel sound.

    Looking at pictures of Tulip domes, it seems that they might be described as closed domes with side vents. Is that a good analogy?

    My new Audi says my new HA will be BTE with closed domes. Is that based soley on my recent audiogram?

    Here's a good article on open and closed fittings. http://www.hearingreview.com/2012/11...-fitting-tips/
    Basically, to get any amplification at low frequencies, one needs a more closed fitting. However, ultimately it's up to you. If you can't stand a closed fitting and won't wear the hearing aids, you'd get more benefit from a more open fitting. It's a balance between "occlusion" and audibility.

    Sorry if I offended. I did some poor editing and part of my comment ended up in the quote. (Since fixed)

    No offence MDB. The "fitting tips" article you pointed to was quite informative. Thank you.

    snevetsm: It would be interesting to know if there is any time-line link between your dad's and father-in-law's dementia and when they finally bought their hearing aids. I've read - and seen first-hand! - how dementia can set in if hearing issues aren't addressed.

    Also know first-hand many grumpy, senior HA wearers who refuse any kind of help with a key communication issue (i.e., hearing). Sometimes their issues begin with earwax build-up due to medications. If not addressed, it spirals out of control to complete inability to carry on conversations, withdrawal, anti-social behavior, and even sparring with their audiologists.

    Considering how critical hearing is, it's amazing to me how little attention, insurance and options are out there to correct the issue early-on.

    Yes: closed domes do sound occluded. The open domes are a way of venting the aids - not unlike the vent holes in ITE-style aids (those with a hard plastic shell).

    I like your description of the tulip dome. I had also tried them out on my Oticon Opn miniRITE aids for a few weeks, but due to my hearing loss, found they were TOO vented.

    It's a process! I had also tried out foam domes that I bought at Amazon.com. They were SUPER comfy, but I couldn't seem to get a proper seal, therefore could not hear on the phone AT ALL.

    When at the audiologist's yesterday, I brought a picture of a "zip tip" - which I'd read about right here on the forum. My aud-guy said he'd fit one patient who had an allergic reaction to the material used. So, that nixed THAT option.

    I now have double-domes, size L, which seem to offer comfort, some breathability and still a good seal for better hearing.

    The argument about which dome isn't really that productive. The more severe the loss, the more closed the domes need to be. When one changes style, the aids need to be readjusted. It may not be what one wishes for but it is what it is.
