The utility model relates to the technical field of headset, discloses a self adjusting headset volume, including: the noise collecting module, when the environmental noise reaches the minimum level and above level, at least one trigger and environmental noise level corresponding loop output signal; signal amplification module, the signal amplification output; the control switch module, according to the received signal after amplification, switch control and the ambient noise level corresponds to the closure, the resistance of the sound output module becomes smaller; the voice output module, and adjusted according to the resistance value of the gain of the external input audio signal output, or when the ambient noise did not reach the lowest level when the standard resistance corresponding to the external input audio signal output gain. Because the utility model can automatically adjust the headset according to external noise output volume, so as to solve the headset to manually adjust the headset volume due to accommodative lag caused the effect to the problem of influence.
