Thank you, Becky, for your quick reply.
I did a lot of reading on the CROS systems, and I wanted one of the Signias, and I chose my audiologist based on the fact that she carried Signias (and many of the other audiologists in my area did not). However, my audiologist uses a Phonak CROS system herself (since she also has SSD), and most all of the advertising in her office was on the Phonak hearing aids. So, I was afraid that she was going to push the Phonak on me, but she did not. She listened to my concerns, and one of them was I was concerned about the Electromagnetic Frequencies traveling through my brain and making my acoustic neuroma worse. Of course, she told me that the EMFs from the hearing devices would not make my AN any worse. But rather than to say that I was crazy for thinking that, she said, "If that is a big concern for you, then I would recommend the Oticon because it has less EMFs." And she told me a story of how the Pentagon only allows Oticon hearing devices in certain areas because the radio frequencies of the others were too high for certain sensitive areas. She showed me some materials on how the Oticon CROS system transmitted differently than the other ones. So, she persuaded me to go with the Oticon CROS system, and I have been happy with it.
But I still have wondered how well the Signia CROS system worked and if I should have gone with it instead. They seem to be built very well. So that's why I appreciate your input on yours. What made you decide to switch from the Phonak to the Signia?
