Systems and methods according to one or more embodiments are provided for a hum reduction circuit implemented to provide a ground path between an audio generating device and a powered headset. In one example, a system includes a jack configured to accept a plug comprising a first electrical ground connection. The system also includes a switch coupled to the jack at a first end and coupled to second electrical ground connection at a second end. The system also includes the switch is configured to couple to the first electrical ground at the first end. The system further includes a bias control signal coupled to the switch, configured to control a switch bias, where a first switch bias electrically couples the first electrical ground to the second electrical ground, and a second switch bias electrically decouples the first electrical ground from the second electrical ground.
