Hello, I am guessing it is a Radio Frequency issue. Your wireless headsets transmit at a frequency that either matches or is a harmonic of that frequency of your radio station and the radio is dutifully playing what is transmitted on that frequency.. As they are wireless devices you cannot add chokes or filters to them. You could try ferrite chokes on the radio but I suspect that it is the radio's antenna picking up the headset signal. So you could try a number of things to separate the 2 devices. Use an external antenna for the radio. Put a large amount of metal between the radio and headset creating a Faraday cage so that the headset signal cannot reach the radio's antenna. See if the headsets have an alternative frequency that they use. Or encourage your wife to use a wired set of headphones. At least to test the hypothesis. If so, and that station is on 780MHZ then you 'll have to look for a different set of wireless headsets that don't use the same frequency that the existing ones do.
