Abstract:
A noise-cancelling headphone is provided that avoids an influence of the wind and prevents degradation in the sound quality of the reproduced sound output from a driver unit. The noise-cancelling headphone includes an ear piece including a housing unit having an interior and an exterior, a driver unit attached to the housing unit, and a microphone collecting external sounds at the exterior of the housing unit. The housing unit includes an accommodating portion accommodating the microphone and a sound collecting hole establishing the communication between the accommodating portion and the exterior of the housing unit. The accommodating portion is disposed in an upper portion of the housing unit of the noise-cancelling headphone when worn by the user. The sound collecting hole is open toward the upper side of the housing unit of the noise-cancelling headphone when worn by the user.
