Weldon: Best way to say it is the voice track is louder thus easier to hear. The music/background noises are diminished. I know you can use a headset if needed, but for me, standard listening with everyone. It puts emphasis on the vocals in the program at a level you can customize. Trying tonight to use my standard TV in my home and already tempted to go out to the RV since the experience was so much rewarding .....two days and my in home unit will be hooked up. My fishing buddy just ordered one today as well.....his wife says he keeps the TV too loud just to hear the words.
