@1Bluejay , i know that theses are no Live aids , but new Naida Lumity SP have 13 battery , and the Sky Lumity SP also powered by 13 zinc-air battery.

#27

Well they do have a 13,

Well if it’s Phonak it’s hardly surprising, it’s all they pushed on people at one stage, but still how many of those that first used rechargeable and found out the hard way how bad it can be and went back to the more dependable zinc air?

If I use recommended prescription - nothing happens, it cannot place sounds into my residual hearing. If I move slider to left to lower frequency stronger - sound S stands before (lower than) sound SH.

I can’t use any model of BTE cuz they require a custom mold - all of the materials I’m allergic to. I can only do RIE aids with a soft, silicone double dome on the speaker. Less than optimal, but I’m VERY grateful they don’t make my ears itch and burn.

I believe custom molds can be done in soft silicone…Maybe one of our audiologists or others in the know will chime in on this.

The production of silicone domes is done by injection moulding, this leaves a surface that is molecularly complete and largely defect free.

Other moulds are produced by 3D printing, forms of casting/hand finishing and using evaporate products, which leaves micro-voids on the product surface and also potentially remnants of the catalyst reaction. Finishing is usually with dipped/UV cured acrylic lacquer, which can be (rarely) hand polished.

Something in one of these processes might be causing a reaction, or simply the micro abrasions/voids in the otherwise perfect surface allow bacterial/fungal production and byproducts to build and irritate the skin. Some people are allergic to the plastics, some to their own bacterial/fungal byproducts, some to both.

This thread was about petition. Can anyone help me write a petition? Are there any lawyers and writers here?

#33

That sure sounds like what could be happening with me. I was never allergic to the smooth, shiny, flesh-colored plastic custom molds when I wore ITEs, but any form of silicone firm or acrylic, and it sets my ears on fire within hours. Bummer.

Perhaps I don’t react to the soft double dome silicone receiver tips cuz they are just a loosey-goosey fit on me - not snug like the custom molds. Thanks for explaining this! Puts my mind at rest.

Ooops, sorry about the digression. Try searching here for legal form or perhaps someone who can help with the petition.

Electronics manufacturers are like politicians. They pay no attention and most likely never even see petitions.

At any company it is the enthusiastic salespeople who are the demigods, as they sit at the point of revenue collection. What customers want and R&D can achieve requires creativity, technical insight and long-term vision, only affecting future sales and the bonus of another CEO- far too distant to bother.

Are titanium moulds not available where you live? I notice they’ve not been mentioned on here other than as tips or for ITC aids. Titanium is hypoallergenic, bio-compatible and yeast and bacteria inhibiting (and looks really cool too). Maybe they’d be an option for you?

In Europe they cost about 150€-200€ each side, which is about double the cost of a normal mould, but providing your ear doesn’t change you can use them forever.

@Lostdeaf

Dimitri, I understand that you want to write a petition (survey?)

However, Phonak has recently shown they watch us here. They responded when a member sent his post with hundreds of responses, and said that Phonak was providing replaceable batteries in Lumity hearing aids where none were available before.

They’ve responded again saying that new receivers with better wax guards would be available for Marvel Paradise and Lumity hearing aids. I’ve been very critical and see this as a necessary improvement.

Until this happened I thougth I would never buy Phonak hearing aids again. I’m very relieved that participation in this forum and helpful criticism has motivated Phonak to modify their product.

I hope this helps you.

Thank you! Yes, I’m thinking of writing a petition, and now I’m composing the text. Phonak are great - they have both superpower hearing aids and a full range of accessories. It’s a pity that their sound doesn’t suit me. The Oticon sound suits me best - but I feel like they’ve neglected the deaf market.

Yes, I’m sure I could get titanium molds for my speakers. I’ve talked to my audi about it. Likely there would be no allergic reaction to that. But my ears swell UP every night and then gradually go down thru the day.

Back in the day of my custom molds made of flesh-colored shiny plastic, I’d have to jam these aids in upon waking (OUCH!) and then by day’s end, they’d be loosy-goosey and I’d start getting squeaky feedback. My feet and even hands have the same issue, but with the ear canals, it’s good to have material that “gives” a bit upon insertion, but then holds fast inside so they don’t fall out.

I DO like the tech look of titanium tho!

Well, you can strike lucky. Years ago I bought an FM radio tuner made by JVC. It whistled under my favourite music station. I opened it up and saw there was no ‘multiplex’ filter - just a factory fitted bypass wire.
Contacted JVC in UK - their reply was ‘There are no user serviceable parts and opening the product will invalidate the guarantee’
So I wrote direct to JVC in Japan. In three days an envelope arrived containing the filter coil plus clear note on how to remove the bypass and fit the coil.
Radio worked beautifully after that, and still does.
I have felt well-disposed towards JVC ever since.

Typical, I wonder if JVC USA will reply the same :thinking:

Well, top marks to Phonak for apparently checking out assorted tips and howls of anguish on this forum. That’s an excellent way to fine-tune product - direct input from actual users.

#45

Correlation does not imply causation. But if you truly believe that Phonak is making major decisions based on a few dozen noisy folks on a forum, then I suggest you start a thread demanding a 50% price reduction. :slight_smile:
