Abstract

A headphone or earphone is provided which includes a housing with an open end and at least one defined dominant acoustic opening, an acoustically sealing earpad arranged at the open end of the housing, and at least one microphone arranged adjacent to common ear or in the vicinity of the dominant acoustical opening for detecting noise. The dominant acoustic opening is arranged within a radius of 2 cm around a midpoint of the at least one microphone. The headphone or earphone also includes an active-noise-compensation unit for performing an active noise compensation based on the output of the microphone and for generating a compensation signal. The headphone or earphone also includes an electro-acoustical transducer inside the housing for reproducing the compensation signal.
