So I have a 2 to 3 year old set of Sennheiser RS 120 II Wireless headphones and after 3 minutes without any audio signal they start broadcasting a very loud annoying static noise. There is no option with the unit itself to turn this off and its really annoying if your using them but don't constantly have audio coming through. You have to switch them off and then on again when you need them. The switching off and on isn't a big deal its more about how obnoxiously annoying, jarring and loud the white noise is when it kicks in.
My question is can the headphones or transmitter be modified to somehow stop this useless feature (which is meant to be an auto off feature)
Or is there a way I can setup an inaudible signal on my pc to keep them live?
