My 102 year old Grandmother has a Roku TV in her nursing home room. She can't hear well so I would like to make it so she can use headphones. Here are the issues. 1) She has no cell phone, so no app. 2) She is bedridden (broke her pelvis) and can't see well enough to plug in a charger, so I need something that will keep a charge for a long time (not rechargeable). 3) Her TV is on MANY hours a day, and she will not be able to unplug the headphones from the remote when she is not using them. 3) The staff will not be consistent at helping her plug in or charge things so that is not an option.
Is there anything that will work?
