I had phonaks most of my life, from child to 22 I had phonak superfonts, (between 16 and 30 didn't wear HA in my left ear) at 22 I got Widex senso for my right ear - I think this is the best HA I ever had, it had to be bought privately by a private sponsor. At 30 my widex started to wear out and died, tried Oction, sienmens, Phonak digitals none were helping me at all, got Cochlear implant for my right ear but because I wanted some sound while I recover and wait for switch on I got unitron analouge HA for my left ear (first time in 14 years) it was great until recently it no longer benefits me (my hearing were unchanged) they gave me extra powerful unitron Analouge HA... still made no difference, I now have Phonak Superos, I had it for 2 weeks and still is not sure of it! every one sounds like they are on helium! But there is a major break through as I finally can tell if my HA battery had died!
