A noise-cancellation wired headset device has a left ear piece, a right ear piece, a control box, first and second cables, and a connector for connecting the control box to a third cable. Each of the ear pieces comprises its own speaker, microphone and battery. The control box includes circuitry including noise cancellation circuitry and a power management unit. The left ear piece battery is connected to supply power to the power management unit by means of the first cable; and the right ear piece battery is connected to supply power to the power management unit by means of the second cable. The power management unit in the control box regulates the supplied battery power and supplies regulated power to control box circuitry. The noise cancellation circuitry is for noise cancellation processing of signals provided by the first and second microphones.
