A headphone device comprising active noise cancellation means (ANC) having a feedback (FB) signal path, a feed forward (FF) signal path and a sidetone signal path, where the headphone is provided with a control member () that can be displaced or rotated between opposite positions, where the control member () is configured such that the gain of the FF signal path and the gain of the sidetone signal path are controllable by the control member () in such manner that when the control member () is at one extreme position, the gain of the FF signal path is maximum and the gain of the sidetone signal path is minimum and when the control member () is at the opposite extreme position, the gain of the FF signal path is minimum and the gain of the sidetone signal path is maximum.
