A listening headset 10 is provided, with a pair of earphones 20 and a head grip 50 attached to the pair of earphones 20 so as to keep the pair of earphones 20 in place on the user's head. Each earphone 20 includes an adjustment element 30 so as to make it possible to adjust, selectively, the earphone 20 between a closed position in which the user's exterior auditory duct is isolated from the sounds which surround him, with the aid of the earphone 20, and an open position in which the user's exterior auditory duct is linked with the outside world. <IMAGE>
