The utility model provides an earphone temperature measurement circuit and an earphone with the earphone temperature measurement circuit, and the earphone temperature measurement circuit comprises a plurality of temperature monitoring circuits which are used for achieving the temperature monitoring of heat source areas inside and outside the earphone. A first heat source area and a second heat source area are distributed in the earphone; the first heat source area is provided with a first temperature monitoring circuit which is used for monitoring the temperature of the first heat source area. The second heat source area is provided with a second temperature monitoring circuit which is used for monitoring the temperature of the second heat source area. According to the scheme of the utility model, the plurality of NTC temperature monitoring circuits are respectively arranged on main heat sources inside and outside the earphone, so that the temperatures of different heat source areas of the earphone can be mon
