Abstract

An earphone arrangement comprises a first and second earphone arranged to operate in a binaural arrangement. An audio data exchange between the earphones supports a binaural processing of the earphone arrangement. The earphones may specifically be hearing aids each of which comprises one or more microphones. An audio environment processor (119) of the hearing aids determines an audio environment characteristic in response to signals from at least one microphone (101, 103) of the first earphone. A binaural controller (117) controls a data rate of an audio data exchange between the first and second earphone in response to the audio environment characteristic. Specifically, the data rate of the audio data exchange may be varied in dependence on a signal to interference ratio, a signal to noise ratio and/or an angle of arrival estimate for an interferer. The approach may typically reduce power consumption and increase battery life.
