I wrote a review here in October '21 about my Phonak top-of-the-range Audeo rechargeable hearing aids that kept turning themselves off whenever I got warm and had a small bit of perspiration behind my ears.
Specsavers offered to change them for the battery version which I gladly accepted. But now I have the same problem with the battery models, though the small advantage is that I can remove the batteries and replace them to switch them back on again.
Phonak advertise that these are category IP68, which as they point out means they can tolerate immersion in 1 metre depth of water for 60 minutes! What nonsense and a wholly untrue and deceptive claim, so how can you believe anything they say?
I tried asking Phonak about this but they refused to comment!
I certainly won't be buying Phonak again.
