I was browsing the Phonak documentation and came across the information here, which used to be exclusive to the NAIDAs:
Based on everything I have seen, it looks like Phonak has simply combined the NAIDAs with the Audeo line, because of the high frequency sound transpositioning here:
I’m good with that. So long as I have a UP version with which is compatible. I’m sure I’ll need rechargeables at some point.
If there is no way to get the random rebooting issues on my Oticons fixed, I may have to eat my words and go rechargeables, and go back to Phonak eventually. The random rebooting is a dealbreaker for me (and the fact that there hasn’t been an update to Xceed’s firmware in years) when it comes to sticking with a hearing aid long term. Had no idea the Oticons even had these issues and I am disappointed.
My main criteria is ensuring that 1. A UP powered version exists, 2. It’s also available on CROS, 3. That it has SoundRecover2. And the Audeo UP has all of these.
The fact that it works using Phonak’s latest chipset looks like it would be a massive bonus too.
Obviously, not happening now. But maybe in another year or two. I need to see what can be done with my existing aids while they are under warranty.

As my old mother would say, now long departed this mortal coil…” Where there is a will, there is a way” it is my fervent hope, Phonak engineers have that “Will”, then it is highly likely, they will find that “Way”… I personally have no objection to a rechargeable Naida Sphere, as long as it has at least a couple of days runtime, something like a “Solid State Battery” might give them that option, and easy access to swap out, would be the ideal scenario, we could then carry, charged up spare batteries… Cheers Kev
