Hello, Bear

The AC adapter for the laptop contains a switchmode power supply (SMPS). That type of power supply is very efficient, but often radiates interference.

It could be causing interference to the TV Ears or to the TV. Does the laptop adapter cause interference to the TV when the TV Ears transmitter is not connected to the TV?
If you can not measure it, you can not improve it.
