In the past 4 months I tried Philips and Biocore ( I think that was the name).
I have a pamphlet from Bernafon Alpha XT. They are a Swiss company, "Sound of Switzerland".
In their given list of countries, USA is listed. Here is the website, it's Canadian, but you should be able to access:
bernafon.ca
These were only released 3 weeks ago in Canada. My provider said this is a new type of technology. And... three times more expensive!
I was in a restaurant this week. It is tough, but they did seem much better than my previous experience, in the same restaurant, with Phonak hearing aids (about 8 months ago).
Hope this helps.
