Abstract:
There is provided headphones for connection to an external active noise compensation device. The headphones have at least one earphone, a microphone near the ear, and a passive circuitry network for increasing the amplification of the external noise compensation device. In that way noise compensation in respect of the external noise compensation can be increased by increasing the overall amplification by the passive network.
