@kem Thanks for clarifying. That does make sense. The Plantronics device sounds impressive, especially since the phone could stream to both hearing aids and you're probably only listening with one ear using the Plantronics, correct? I'm assuming you have "Made for iPhone" models of Resounds. There should be ALMOST no reason that your Resounds could not be tweeked to match the performance of the Plantronic device. It's very possible that the frequency response of the hearing aid is not as good as the Plantronics. Most hearing aids only go up to about 8000 Hz, I think. In that case, I can understand why the Plantronic device is superior. Some speech sounds are higher than 8000 Hz. The problem is finding an audiologist that is willing to work with you. I'd appreciate if you could give me the model of that device so I could look up the specs.
