I started using a device called TV Ears when my hearing was diagnosed as heading south. Kind of a crude set of bluetooth-like headphones that boost the dialog. Without them I typically would crank up the volume to the point where my wife was irritated, or leave it so low that I could not pick up any dialog. I must say they have been very helpful. I can even use them and turn the TV sound down to zero - they have a separate volume control. I wish they were more comfortable, but nothing else I've tried is as effective. I'ver had them for a couple years. Replaced the rechargeable battery once so far. YMMV
