Abstract
The invention relates to an earphone () with leakage control, which can be switched between states with and without leakage to adapt the earphone to different listening situations. The leakage of the earphone may be enabled and disabled automatically in dependence of the sound source and/or may be controlled manually by the user. The earphone is connectable to a device and comprises: a housing () substantially covering the external auditory meatus, and accommodating a loudspeaker element (); the housing further comprising a channel () extending between an inner end () facing the external auditory meatus, and an outer end () facing the environment; and closure means () being switchable between a closed state in which said channel is substantially closed, and an open state in which said channel is admitting sound from the environment. The invention also relates to a device co-operating therewith, such as a mobile telephone.
