Much richer sound than any TV can produce. Great for people who have slight hearing problem, great for people who are not native English speakers (you will understand twice as much when it comes to fast dialogues during movies).

A little hissing sound -- minor. A small delay in the sound through the headsets compared to the sound coming out of the TV: you won't be able to use the headphones while somebody else is using the TV speaker

We bought the HDR 120 system about 6 months ago. We are so happy with it that we are buying a second unit.

Added bonus: we can now have quiet conversations while our kids watch TV: no more obnoxious cartoon sounds during dinner! A great investment for the $.
