Among them, most of the existing Bluetooth headsets on the market cannot rotate, and a small number of rotatable Bluetooth headsets also rotate around the center of the circle. Their disadvantages are: (1) The headset and the ear hook are loose; (2) It is unstable when rotating; (3) There is a large intermittent position between the headset and the ear hook when rotating; (4) It is easy to pinch the user's flesh. Boys have larger auricles and girls have smaller auricles. If the headset is worn in the same position for a long time, the auricle will be uncomfortable. Slightly rotating it can relieve the fatigue of the auricle. It is also convenient to adjust the appropriate tightness during exercise and leisure. It should be tighter during exercise to prevent falling, and looser during leisure. Content of the Utility Model
