The earphone () is adapted to be arranged in an operating position at a first ear () of a user () and, in the operating position, provide a first acoustic output signal (S) to the first ear (). The earphone has a first input unit () adapted to receive a first audio input signal (S); a first noise cancellation signal path () with a first microphone () and a first noise cancellation filter (), wherein the first microphone () is arranged to receive ambient sound (S) from ambient space () with the earphone in the operating position and is adapted to provide a corresponding first reference signal (S), and wherein the first noise cancellation filter () is adapted to apply a first transfer function (H) to the first reference signal (S) to provide a first noise cancellation signal (S).

Headset with active noise cancellation

A signal processor () for a headset () configured with a microphone terminal () for receiving a microphone signal, a loudspeaker terminal () for outputting a loudspeaker signal, and a far-end terminal () for communicating an inbound signal and an outbound signal with a far-end; comprising: a side-tone path () configured to generate a side-tone signal from the microphone signal via a controllable side-tone filter; wherein a side-tone filter controller () receives the microphone signal and computes a first noise estimate with a signal-to-noise level of the microphone signal at respective frequency bands and based thereon controls the side-tone filter () to improve or optimize a signal-to-noise ratio.
