The system comprises audio headsets able to apply audio processing operations in response to presets that are common to all the headsets, smart terminals provided with audio flow generation means, and communication means to transmit to the headsets an audio flow and presets to be applied to this flow. A preset server memorises the presets associated with works. Certain terminals can generate presets and transmit them to the server, whereas other terminals collect these presets to apply them to the corresponding works at the time of reproducing these latter.
