Battery dimensions:
If I was new to hearing aids, I’d be self conscious, but I’ve learned that nobody really sees them, or cares. Everyone has something in their ears these days
Having said that, I’m a 60+ male. It will be different for younger people, more fashion conscious or vain, although I feel the stigma is nowhere near as bad now. Still, for marketing, these are important issues.
312 are lovely and keep my Bolero Marvel M70s thin. 4 days is ok, and a strip takes up little room in my wallet.
13 are bigger, so make my Audeo P90s wider, but (being RIC), the aids are really small. I get a decent 6 days out of these.
675 are substantial, as are the Naida P30s. I wear these with full molds. They’ve a much bigger hearing aid, but no bigger than a Venture with shoes and RogerXs. I’ve had these about 10 days and still on 1st batteries.
I can only comment on Phonak, but I see the majority of rechargeable aids are bigger than the disposable equivalent.
Another major issue I read, is that Phonak aren’t the leaders in rechargeable daily battery life, compared to companies like Starkey.
I hope this helps.
