My grandparents are getting old, and they both seem to have this hearing problem when watching the tv, my grandma has the worst hearing so she blasts the TV to the loudest volume so she can hear, but my grandpa has just slightly less than normal hearing and he gets irritated by it, he wanted to get some wireless headphones so they both can regulate the volume accordly
anyone have any idea of some headphones with this capability?

 

Two Tv's ??

 

one tv, 2 earphones
