Hi [USER=4646]@advid[/USER] Welcome;
Typically a hearing aid wearer will want to "Stream" the sound directly into their hearing aids to get clear surround-sound audio directly into each hearing aid. Yes, surround-sound with helicopters flying overhead from left to right/front to back etc.
You will need a TV TV Adapter device connected to your TV/System usually connected via TOSlink/Optical Audio and then you "Pair" your hearing aids to the TV Adapter.
What model hearing aid do you have. Legacy HAs may not support streaming.
