<p>Headphones are disclosed that can cancel noise input from external sources. The headphone includes a microphone, an attenuation circuit, a speaker, a headphone housing and an ear pad whose buffering member is wrapped by an outer skin. The buffering member contains a plurality of micro-spaces to which air is permeated. The outer skin forms a plurality of audio sound through-holes. Since the buffering member fills the whole inside of the ear pad, it provides a user with a snug, comfortable fit when the user wears the earphones and can manually reduce external noise that flows in from the outside to the ear canal. Although the ear pads are subject to pressure from external environment factors, such as the user's hands, etc. and thus the air is compressed within the headphones, the buffering member can buffer the pressure through its plurality of micro-spaces into which air permeates. In addition, since the buffering member fills the whole inside of the ear pad, the headphone substantially extends the audio sound space and thus can reduce the generation of the acoustic feedback.</p> |
