PROBLEM TO BE SOLVED: To provide a particular sound reproducing apparatus and a particular sound reproducing headphone capable of correctly acquiring required sound emitted at the outside of a space in the sound shielded space and keeping stillness in other cases. SOLUTION: The particular sound reproducing apparatus 1 buffers sound picked up by a microphone 2 to a sound storage section 12, discriminates the presence/no presence of phrases and sound patterns registered in advance in a sound pattern registration section 17, and when the particular sound reproducing apparatus 1 detects the registered phrases and sound patterns, the particular sound reproducing apparatus 1 reads a sound just before the recording of the phrases and sound patterns from the sound storage section 12 and emits the sound from a speaker 3. Thus, a user 6 passes a time indoor (in-room) wherein outdoor noise is shielded ordinarily and stillness is maintained, and when sound including the registered phrases and sound patterns is emitted outdoor, since the particular sound reproducing apparatus 1 detects it and emits the recorded sound, the user does not fail to catch the registered phrases or the like.
