Abstract
An audio headset may comprise a case, near field microphone and far field microphone. A speaker, processor, memory, battery, charging interface and cradle detection circuit may be mounted to the case. Processor-executable instructions embodied in the memory, may be configured to implement a battery charging method. The headset may be shut off in response to placement of the headset in a charging cradle. The far-field microphone is turned on but not the near-field microphone. The battery may then be charged from the cradle. A headset having near-field and far-field microphones may be used to distinguish between user speech and competing sounds by generating signals from the sounds detected by each microphone and comparing the strengths of the signals. The signals may be processed as user speech if they are of comparable strength. Otherwise, the near-field signal may be processed as user speech and the far-field signal as competing sounds.
