Read this to find about generic telecoil–across all brands of hearing aids: " Install Telecoil or Not in your hearing aids?
Of course, each brand makes their telecoil/bluetooth versions of Hearing Assistive Devices, which cost a lot of money. But you can get “generic” telecoil for a lot cheaper (which doesn’t have the bluetooth capability). So these $60 neck loops use cords and can be plugged into many devices, including any device that has a headphone jack. I even used my $60 neck loop on the airplane to listen to their movies–a bonus was that it blocked out background airline humming noise really well. I put it on (manually) my telecoil setting in my hearing aid. Outstanding experience! (NOTE: The Automatic telecoil setting doesn’t block out background noise nearly as well.)
