Abstract

There is provided a headset having at least one microphone for detecting ambient noises, at least one electroacoustic reproduction transducer and a control unit for controlling the headset. The headset also has a digital active noise reduction unit for performing digital active noise reduction based on the ambient noises recorded by the microphone. The headset further has a data interface for receiving data and/or parameters for the headset and for outputting data and/or parameters stored in the headset.

Claims

1. A headset comprising:

at least one microphone for detecting the ambient noises;

at least one electroacoustic reproduction transducer for outputting an audio signal to be reproduced;

a control unit for controlling the headset;

a digital active noise reduction unit for performing active noise reduction based on the ambient noises recorded by the microphone; and

a data interface for receiving data and/or parameters for the headset and for outputting data and/or parameters stored in the headset.

2. The headset as set forth in claim 1;

wherein the data interface is adapted to update the control of the control unit.

3. The headset as set forth in claim 1, or further comprising:

a wireless data interface for transmitting and receiving data and/or parameters from or for the headset.

5. The headset as set forth in claim 2, further comprising:

a wireless data interface for transmitting and receiving data and/or parameters from or for the headset.

4. An earphone comprising:

at least one microphone for detecting the ambient noises;

at least one electroacoustic reproduction transducer for outputting an audio signal to be reproduced;

a control unit for controlling the earphone;

a digital active noise reduction unit for performing active noise reduction based on the ambient noises recorded by the microphone; and

a data interface for receiving data and/or parameters for the earphone and for outputting data and/or parameters stored in the earphone.
