Is your partner already working with an audiologist / ENT to correctly identify the extent of the hearing loss and what the best strategies would be to deal with this? Seriously, that really needs to be the first step. Throwing a set of AirPods at her isn't going to serve in the long term (or even the short term) to resolve her hearing situation.
She's worked with an audiologist / ENT to correctly identify the source and extent of her hearing loss, so she's very familiar with what's affecting her. She was diagnosed at 15, and wore hearing aids at that time until her early-20s. She later realized they didn't make much difference apart from providing some level volume control over what she was hearing. The issue is that the hearing aids that she that
should have given her current level of hearing loss are extremely expensive (about $3,000 CAD per ear), and according to conversations she's had with her dad who's experienced with using hearing aids, she'll have to replace them every couple of years.
Of course, her dad, who's a retired civil servant/law enforcement officer, has health coverage to make sure he's set for life with top-of-the-line hearing aids. He's refused to support her getting any (for reasons I won't get into here), and her current insurance only covers a miniscule amount of the cost. (Can you tell I'm a little salty about that?)
And yes, throwing a set of AirPods Pro 2 (or the HP Hearing Pro, or the Nuheara IQbuds 2 Max) at her won't solve her hearing issues. But they're at least something she can use to ameliorate the day-to-day issues she faces with conversations in various aural environments, since she simply doesn't have access to the kind of money needed for prescribed hearing aids.
It's a potentially viable option that's at least better than what she's got now, which is nothing.
Thanks so much for that link. My partner has the same level of hearing loss as the author of that article, so it's great getting their in-depth perspective on the competitive landscape of sound-amplifying Bluetooth earbuds. I didn't even know products like the Senheisers or the HP buds even existed. She's in the market for getting a new phone so an iPhone is potentially in the cards, which will open up the AirPods Pro 2 as an option for her.
