I have Costco KS-10 which are to all intents and puposes Phonak Marvels. Fairly pleased with them but the main problem of speech in noise still evades the technology. I look forward to next generation hearing aids which I think we should see soon as tech progress is exponential. There are a number of interesting technologies knocking around and what we need now is powerful enough processor to incorporate them all and more at low battery drain. 2026?
