摘要： A headset or earphone is provided, having an electro-acoustic reproduction transducer (10) with an oscillator coil (11) arranged in an axis. An amplifier (20) is coupled to the electro-acoustic reproduction transducer (10). The headset or earphone also has a magnetic interference sensor (50) for measuring a magnetic interference field. A correction unit (40), for analyzing an output of the magnetic interference sensor and for producing a compensation signal, is coupled to the magnetic interference sensor (50). In addition, the headset or earphone also includes an adding unit (30) for adding the compensation signal to an input signal and for outputting the result to the amplifier (20).

摘要： The invention relates to an in-ear headphone comprising a housing (100), a converter housing (200), and a supporting unit (300). The converter housing (200) is used to receive an electroacoustic converter. The supporting unit (300) is connected to the housing (100) and is designed to be fixed in a concha of a carrier. The supporting unit (300) at least partially consists of a soft flexible material. In this way, the in-ear headphone can be fixed in any concha of a carrier.
