Abstract
Existing ANC headsets have active noise reduction circuitry and a power supply in the headset. Alternate ANC headsets rely on ANC circuitry in the player and have non-standard connectors meaning that they cannot be used with any other players. An audio headset () having an encoder () and active noise cancellation audio processing device () having a decoder () are described. The encoder () enables the audio headset to be used in enhanced (ANC) mode when connected to a compatible audio processing device and in normal mode when connected to a non-compatible audio processing device since a standard audio jack plug can be used. Similarly the decoder () in the active noise cancellation audio processing device () enables the active noise cancellation audio processing device to be used in enhanced mode when connected to a compatible audio headset and in normal mode connected to a non-compatible audio headset since a standard audio socket can be used.
