Episode 1532 (1:13:23)

Seth from Long Beach, CA
Sennheiser RS 120 II

Both of Seth's parents are now hard of hearing and they need headphones to watch TV. Is there a system that can do it for them? Leo says that hearing aids now can pair to the TV. So if they need a hearing aid, that's a good feature to get. But if he wants headphones, Leo got his mother a pair of Sennheiser wireless RF headphones. They work much better than Bluetooth.
