摘要

The headphone (5) has a microphone (40) for detecting ambient noise. An active noise compensation unit (30) produces a compensation signal based on the detected noise. Transducers (10, 20) reproduce an audio signal and the compensation signal. The transducers have different diameters. A housing (50) includes an end (51) provided on a side facing away from ears, and another end (52) on a side facing towards the ears during wearing the headphone. One of the transducers (20) is provided in or at the latter end. The other transducer (10) is provided in a centre section (53) or in the former end.
