Abstract
A headset device with active noise reduction includes a housing configured to be mounted near or in a human ear, a speaker unit equipped within the housing and configured to emit a sound signal, one or more microphone units configured to collect ambient sound and a signal processor electrically connected to the one or more microphone units. The signal processor is configured to selectively operate either in a hearing aid mode in which ambient sound coming in from the outside through the one or more microphone units is emitted, or in a noise reduction mode in which ambient sound coming in from the outside is inverted and the inverted ambient sound is emitted through the speaker unit to reduce the ambient sound. A corresponding method of operating the headset device is also provided.
