1. A hearing assistive device comprising:
a multi-microphone system for providing a processed input signal, the multi-microphone system comprising:
a multitude of microphones for picking up sound from an environment of the hearing assistive device, each of said multitude of microphones providing an electric input signal representing said sound;
a beamformer filter configured to receive said electric input signals, or signals originating therefrom, and to provide a spatially filtered signal in dependence of said electric input signals and fixed or adaptively determined beamformer weights;
an attachment element configured to fix the hearing assistive device to the body or clothes of a person, the attachment element being configured to be in different first, open and second, closed states; and
wherein the multi-microphone system is configurable to operate in at least two modes in dependence of a mode control signal, said at least two modes comprising:
a) a directional mode wherein said multi-microphone system is configured to provide said processed input signal as a directional signal,
b) an omni-directional mode wherein said multi-microphone system is configured to provide said processed input signal as a omni-directional signal; and
wherein the attachment element is configured to provide an electric signal indicative of a current state of the attachment element; and
wherein the hearing assistive device further comprises:
a mode controller for providing said mode control signal in dependence of said electric signal indicative of the current state of the attachment element;
wherein the attachment element in said first, open, state is configured to be attached to clothing or other body-worn items, and to enter said directional mode; and
wherein the attachment element in said second, closed, state is configured to be un-attached to clothing or other body-worn items, and to enter said omni-directional mode.
 
16. A hearing assistive device comprising a processor for processing an input audio signal and providing a processed input signal, and an attachment element comprising first and second mutually movable mechanical parts allowing the attachment element to grip an item, the hearing assistive device being configured to control said processing in the hearing assistive device in dependence of the attachment element being in a first or second state determined by monitoring a current flowing through said first and second mutually movable mechanical parts.
