Abstract
An induction-type loopset is provided that is connectable to a wireless device. The loopset contains a first coil electromagnetically coupled to a t-coil hearing aid and an impedance-matching device coupled to the first coil. The impedance-matching device is responsive to an audio signal from the wireless device. The induction-type loopset is powered from the power source of the wireless device. The power source is responsive to an activation state of the wireless device.
