[0002] A Bluetooth headset is a device that applies Bluetooth technology to hands-free headsets, allowing users to get rid of the constraints of wires and easily talk in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business users to improve efficiency. Bluetooth headsets work in the microwave frequency band, with a transmission rate of 1M bytes per second and a maximum transmission distance of 10 meters, which can be increased to 100 meters by increasing the transmission power.

[0003] A Chinese patent application CN208623872U discloses a portable headset, the key points of its technical solution are: by setting up a portable headset, the bottoms of the two ends of the head-mounted ear hook are respectively connected with a first earmuff and a second earmuff through telescopic arms, and the telescopic arms are used to facilitate the adjustment of the length of the head-mounted ear hook to adapt to people with different head circumferences. A first slide groove is provided on the outer side of the first earmuff, and a data plug is provided on the inner wall of one side of the first slide groove. The Bluetooth headset is installed and connected to the first slide groove, and the data plug is plugged into the Bluetooth headset, so that the Bluetooth headset can be charged during installation and can be used directly at ordinary times. When traveling on business trips or sharing with others, the Bluetooth headset and earplugs can be taken out by opening the sliding cover.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: there are many types of Bluetooth headsets, and the most commonly used ones are head-mounted Bluetooth headsets. Since the ear frames on most head-mounted Bluetooth headsets lack protective mechanisms, they will be contaminated with hair oil during long-term use, and there will also be problems of mutual wear between the ear frames and the hair; therefore, a head-mounted portable Bluetooth headset is proposed to address the above problems.
