    The way I understand what Neville is saying is that hard molds may be a little less forgiving than soft molds because if your ear canals vary from time to time (for example they may swell up or contract during the course of the day maybe from your sleep/wake cycle), the soft molds can be compressed or expand a little bit to always provide a snug fit to your ear canals as the canals may vary in size. But if you use a hard mold and it was made while your ear canal was a little more expanded for some reason, then when your canal opens up a little, then the hard mold won't expand up like the soft mold to continue to provide a snug fit anymore.

    So even if the impression and hard mold are made correctly, if they're made at the time when the ear canal expands,then the hard mold may not be snug enough. If the other way around (when the ear canal opens up more), then the hard mold may be made too snug. For folks whose ear canals don't change much then this may not be a big issue, but I think there are folks whose ear canals may change on a daily basis based on their sleep/wake cycle or other factors. Or maybe just changing in size gradually over time.

    The only thing I can think of is for aesthetic reasons if the tube is more visible than the wire, and the BTE is probably usually bigger than the RIC HA. But if he doesn't care about this then I agree, don't see why not.

    Studies have shown that the acoustic seal of various types of molds and mold materials make very little difference in patient satisfaction. Exceptions are excessive jaw movement or someone who is active in sports who may get hit in the ear, in this case vinyl or silicone molds would be the one to go with. Acrylic molds do not shrink, change shape or get hard with time. It also is the easiest to reshape and re tube and is also the easiest to insert in the ear. The ear does not really change size or shape unless you gain or lose 5 lbs or more or you have excessive jaw movement when you chew. If the mold is made correctly you should be good to go for a number of years with a hard mold. As we age the ear canal tissues can thin and lead to problems with hard molds. One thing to remember is an earmold should never hurt, if it does something is wrong.

    Yeah? Really?

    Can I see the sources for those.

    Silicone moulds are used to achieve better acoustic seal than harder materials, not especially for active individuals.

    There's at least five different modulus acrylics on the market. From fully hard to one that's about 35 shore iirc.

    The insertion argument is bogus, especially when you see the number of people who fails get acrylic moulds fitted under their anti-helix.

    You might want to think about your level of confirmation bias when posting this kind of info.

    Could we please get back on track with original query from original poster about giving Costco a try for a hearing aid fitting? I have a similar loss and need for a new aid in the near future. I use silicone molds with medium size vent holes and am curious about the success of ric molds for high power needs.

    I also have size 675 batteries which give me 8 to 9 days of power. Most aids that Costco have seem to use the smaller size 13 battery. I hate the idea of replacing the batteries every 5 days.

    I don't know, but I don't think Costco carries super power hearing aids. Depending on how valuable your time is, if you're already a Costco member, it couldn't hurt to visit and find out.

    Sorry, I used The Hearing Review as well as Audiology Online as a couple of sources of information. I take it you don't agree with them.

    Costco is just like any other hearing aid center: they have good ones and they have bad ones, the trick is to find the good one and go there. Where Costco kills the competition is their price, warranties, trial periods and full 100% refund if you don't keep the aids. They will also give you lifetime adjustments as long as you have the HA's. They will only service the aids for a maximum of 5 years, although you can get the HA's fixed at private repair shops. Their product line is not old technology as some audiologist would have you believe, although it might be missing one or two features found on HA's sold by audiologist. You really have nothing to lose going to Costco except your time if you end up not keeping the HA's.

    I really don't see the downside to trying Costco.. Don't cost nothing in the end if you return them.

    BTW, most OP question seem get lost as more and more folks hijack a thread.

    OP here, to follow up...

    I went to Costco this morning and had a hearing test and talked to the dispenser. I was favorably impressed. The hearing test was as good as any I've had from an audiologist (no significant change from the one in my sig) and he seemed be knowledgeable and willing to work with me. I came in leaning toward the Brio 2 and he agreed with that. He suggested either the BTE or the custom RIC (I think that's the correct term...the RIC that's imbedded in a custom mold). While I've always had BTEs, I'm kind of leaning toward the custom RIC, partly to try something new and partly to get away from the big clunky tubes & ear molds. If they don't work out I'll try the BTEs.

    As mentioned above, I did try RICs once with the soft dome and they didn't work out for me. To be honest about it, I think it was mostly that I just didn't want to mess with them at the time. I think I could probably have gotten them to work if I'd had the inclination.

    At any rate, at this point I'm thinking I'll go with them. The price & 180 day trial period make it hard to pass up. Not much to lose but time and I'm retired.

    Thanks to all for the inputs (even of they did wander a bit off topic ).
