Both my son and DH wear invisible headphones!
My husband listens to stuff on his phone, eg sports commentaries, via his Bluetooth hearing aids.
I can't tell, so I just talk to him as normal and he genuinely doesn't hear me.
Then when I get his attention there's a lot of,
"Ooh, ooh, hang about, just a minute, there, hang on, what was it?" while he faffs about switching it off and is eventually ready to listen to me.
By which time I'm probably in another room doing something else as the moment has passed 🙄
