I have a hearing problem as well, but mine is mostly hearing voices clearly in a crowd, but I found a good set of Bose headphones that are wireless. I got them mainly to keep from waking my wife at night. I have a sleep disorder and I am up all hours of the night. Like you, I notice things my wife doesn't even see. It drives me nuts when I see impurities in the picture, and when a digital channel is breaking up, it's even worse. I was in the satellite business for nearly 30 years, and being a bit of a perfectionist, I notice things most people don't see. One of the hardest things I had to do was getting customers to recognize the benefits of quality equipment.
When I bought my first FTA receiver, I was very skeptical about its quality. I was not used to buying satellite receivers for a hundred bucks. I did some research before buying, and maybe there are better choices than the HDVR1200, and if there is, I welcome any suggestions. I am glad you figured out a solution to your problem. I didn't realize you had a hearing problem. So far, I am very pleased with the channels I found, and I hope we don't end up on FTA like we did with C-Band in the early days. The programmers realized there was a huge market and that's when they started scrambling their signals. Hopefully that won't happen with FTA.
