TV Ears 10041 Original System (Black)
They work!
TV Ears do not just amplify the sound.  They have a circuit that emphasizes treble, which makes voices much clearer.  This works.  As an older male user, my hearing is impared mainly in the upper regions.  When I use the TV ears, I can understand speech much better.  The battery/charger seems to be very good.  I can listen all evening without running out of battery.  Just remember to put the ears on the charger the next morning.  There is plenty of volume - much more than I need.  I guess this means they will work for people with more severe hearing problems.  There are separate volume and tone controls on the headset receiver, making it easy to tune the sound to your liking.  The only down side is that the headset band doesn't go over the head.  The apparatus is suspended from your ears.  This is a little bit uncomfortable.  This only dampens my enthusiasm a little, because the ears do such a great job!  The price is pretty steep, and I was worried about spending so much.  But, I am very satisfied with this product.
