    Abstract: A hands free communication device (2), such as a headset, adapted to be simultaneously connected to a first telecommunication device (2) and a second telecommunication device (3). The hands free communication device (2) is adapted to send a call status signal to the first telecommunication device (3) upon reception of a corresponding call status signal from the second telecommunication device (4) and to send a call status signal to the second telecommunication device (4) upon reception of a corresponding call status signal from the first telecommunication device (3). The invention also relates to a system implementing such a hands free device (2) and a method using such a system.

    Abstract: Noise cancelling headsets and a method of improving audio sensitivity for a headset are disclosed. The headset comprises a speaker, a microphone unit comprising at least a first and a second microphone for picking up incoming sound and generating a first audio signal generated at least partly from the at least first microphone and a second audio signal being at least partly generated from the at least second microphone, a signal processor being configured to receive and analyse the first audio signal and the second audio signal to determine one or more equalization filter coefficients, an equalization filter configured to receive the second audio signal and the one or more equalization coefficients, and to equalize the second audio signal according to the determined one or more equalization filter coefficients to provide an output audio signal, wherein the one or more equalization filter coefficient are determined so as to approximate a power spectrum of the output audio signal to a power spectrum of the first audio signal.

    Abstract: The present invention is directed to, amongst other things, detection of the causes of communications failures primarily between a base station and wireless headset and then taking action in response thereto, such as notifying the user wearing the headset. The wireless telephone sound interface device (2, 22) is characterized in that the device controller (41) further is adapted to estimate a disconnection cause for said disconnection and to control the electronic circuit (42-49) in dependence on the estimated disconnection cause.This may allow the wireless telephone sound interface device (2, 22) to avoid superfluously alerting the user of a disconnection deliberately caused by the user and may thus aid in reducing daily annoyance of the user and/or of colleagues in a working environment.
