On my AirPods. And I hate them. That's no criticism of AirPods... I suppose they are actually very good... I just don't like using ear buds OR headphones..... although for movies they do help, a LOT.
Reading up on the hearing aids I'm getting they have a device for TV's that allow you to connect, then adjust the sound, without interfering with the others in the room watching and listening thru my speakers. Hmmmm.... I think I'd like to test it before buying... I'm a bit skeptical that it would work. - JamesJM
