Thanks for the link. I wondered where those seals had gone
I used to use those seals when playing soccer. They’re basically like a condom that fits over the hearing aid. You have to use the tool pictured to stretch out the seal enough to put over the hearing aid. They actually work pretty well – despite being difficult to put on the hearing aids – but they definitely don’t totally encase the hearing aid. I really doubt they’d work for swimming or water dunks of more than a few seconds.
I did call iHear the other day and they said no way they’d use their aids in the water.
Also, the UK manufacturer of IP 68 hearing aids seems to produce “shooters” hearing aids – hearing aids for competitive shooters that have a hearing loss. If you could get them, they might work but their settings are all tied to different types of shooting competitions. So, I’m not thinking that’s much of a solution either.
