Query: Great Headphones

For several years I denied that my sense of hearing diminished due to old age. This headphone solved the problem. The only thing I find annoying is that the volume of the TV must be turned up enough so that the headphones can pick up the signal. But the volume required doesn't disturb others in the house who prefer to sleep. My pet gripe is that actors on nearly all TV dramas seem to think that moving one's lips and pronouncing their lines distinctly is unrealistic. Then, the sound recorder dubs in the background music too loud realtive to the actors' mumblings. Also, when commercials come on, you have to adjust the headphones volume. But you can't have your sound and hear it too.
