Let me comment on: “Using a telecoil is equally cordless as bluetooth”
Actually I have two neckloops–one is cordless and one is not cordless. I believe that it is the “bluetooth” technology in the one that is cordless that makes it cordless–not telecoil. Telecoil is “loop” technology. . For bluetooth you have to “pair” two devices. For telecoil you don’t do anything like that. I realize that the two technologies can be combined or be separate.
I am not talking here about the hearing aid manufacturers’ technology, as I am not privy to how they combine (or don’t) the two technologies, with their patents, etc. I am only talking about the copper telecoil in your hearing aids, & room/neck/counter looping technology, etc.
You may be talking about the fact that there is no cord between your hearing aids and the neckloop. That is true but that is because of magnetic conduction technology --which is telecoil & not bluetooth. (Notice that you don’t pair your hearing aids with your neckloop.)
Actually I think we are saying the same thing–just expressing it differently.
