If you have a husband like my Keith, this product is well worth the money. My life has been a lot quieter since we got this.
Keith can't watch TV without having the volume maxed out. It makes me nuts. With the TV Listener, we can have our own individual volume level - his blasting and mine normal.
I am not associated with anything concerning this product, just a satisfied customer.

That's where I bought ours. Since then, I've seen them at CVS Pharmacy.
