1. A hearing aid configured to be worn by a user at or in an ear of the user, the hearing aid comprising
at least two input transducers configured to pick up a sound at said at least two input transducers and to convert the sound to respective at least two electric input signals representative of said sound,
a first filter for filtering said at least two electric input signals and providing a first filtered signal,
an output transducer for converting said first filtered signal, or a signal derived therefrom, to stimuli perceivable by the user as sound,
a second filter for filtering said at least two electric input signals and providing a second filtered signal comprising a current estimate of the user's own voice,
a transceiver for establishing an audio link to an external communication device,
a controller configured to allow the hearing aid to operate in at least two modes, a communication mode wherein said audio link to said external communication device is established, and at least one non-communication mode,
wherein each of the first and second filters are configured to operate in a more power consuming and a less power consuming mode in dependence of said controller, and
wherein said controller, when said hearing aid is in said communication mode, is configured to
set said first filter in said less power consuming mode, and
set said second filter in said more power consuming mode.
