Receivers normally have 1/4” jacks for headphones as this Denon AVR-1912 does (not 1/2”). You don’t give enough information for a solution but if the person is mostly listening to TV and the TV has bluetooth then get them a set of BT true wireless earbuds which are more comfortable than headphones. Go to Amazon and search for Boltune Bluetooth 5.0 Earbuds as an example. The Denon receiver can be set up to send the audio to the TV if it is connected with an HDMI cable. When the earbuds are taken out of the case it should connect to the TV and the TV sound should mute automatically. You will have to pair the earbuds with TV before this works but this should be required only once. I don’t know if the audio will come through the TV for other sources such as Radio. but if a cable box is used for TV they usually provide music channels. The receiver does not have bluetooth.
