description	PROBLEM TO BE SOLVED: To easily detach and adjust a bone microphone by constituting a head set of an ear muff incorporating a speaker for reproducing a sound signal from the outside a bone microphone for outputting the vibration signal of the voice of user to the outside, and a retainer freely attaching and detaching the bone microphone on the ear muff and a support for pressing the microphone corresponding to the shape of the facial bone of the user. SOLUTION: The outer peripheral of a disc-shaped speaker baffle 16 is fixed with a small pin 21 by a fixture 22 on the inside face of a side wall 14a in the neighborhood of the bottom of a housing, and a speaker 15 is fixed almost at the central part of the speaker baffle 16. A bottom 14b of the housing is shaped like a disc except the inside, and the outer peripheral is provided with a projecting stepped part at a speaker 15, and a retainer hole 23 is formed at the stepped part. A stopper screw 18a is freely attachable and detachable retained to the hole, and a projecting part 18b is interfit into the inside face of the side wall 14a so that the housing can be surely connected with an ear pad, and this can be easily detached as necessary.
