A radio frequency filtering circuit for audio headphones includes a switching power supply, audio amplifier section, one or more outputs from the audio amplifier section to one or more corresponding channels of the audio headphones, one or more L-C low pass filters arranged between the switching power supply and the audio amplifier section, and one or more L-C low pass filters arranged between the audio amplifier section and the one or more corresponding channels of the audio headphones. A method of filtering radio frequency signals for audio headphones includes providing an input voltage from a switching power supply section of a filtering circuit, passing the input voltage through an L-C low pass filter arranged between the switching power supply section and an audio amplifier section, and passing an output of the audio amplifier section through a second L-C low pass filter arranged between the audio amplifier section and an audio output to the headphones.
