Donna:
I have 'TV Ears' and like them. My wife bought them as a Christmas gift about 6 months after my surgery, in 2006. We had the usual tug-of-war over the loudness of the TV and she was afraid her hearing would be harmed by having it loud, as I required. The TV Ears solved that problem. She can set the volume quite low and I just turn up the 'gain' on my headphones and hear the TV perfectly.
The drawbacks are as follows: The sound is somewhat 'tinny' as it usually is with small headphones. Programs with loud audience cheering, as on some game shows, comes through as white noise, because the sound overloads the capacity of the headphones to process it. The soft cushions on the ear-pieces fell off within a few months and I cannot get them back on so I simply do without them. Not a big deal. If you have (or plan to purchase) a Hi Definition TV, you'll need an adapter. They sell 'TV Ears' for Hi-Def but the salesman told my wife they don't work all that well and the adapter on the 'original' model is the way to go.
Other then those caveats, 'TV Ears' work just as advertised. They are light, comfortable and easily rechargeable (they sit in a stand that acts as the charger). Not cheap and not like normal hearing but as good as it gets, I suppose. Anyway, they work for me.
