Compared with the prior art, the utility model has the advantages that the shell is connected with the speaker through the ear hook, and is hung on the ear through the ear hook, which is convenient for wearing; The round sound hole facilitates the transmission of the sound of the speaker, the sound-absorbing layer effectively isolates external noise, the anti-slip sleeve improves the stability of the speaker placed in the ear hole, and greatly increases the user's experience of use. The hinged relationship of the body can be rotated, so as to shorten the distance between the microphone on the link and the sound source, and improve the quality of the call.

As an improvement, the operation keys include volume up, power switch and volume down.

As an improvement, a protective cover is buckled on the USB charging hole, and one end of the protective cover is hinged with the housing to prevent dirt from blocking the USB charging hole.

As an improvement, the sound-absorbing layer is made of sound-absorbing cotton material, the sound-absorbing cotton has high sound absorption rate, good sound insulation performance, and has excellent waterproof, moisture-proof and breathable performance, which increases the comfortable experience of wearing.

As an improvement, the non-slip sleeves and ear hooks are made of silicone material, and the earplugs are provided with an anti-slip sleeve made of silicone material to prevent the earphones from falling off during wearing, and at the same time provide a certain guarantee for the sound insulation effect of the sound-absorbing layer , The ear hook further improves the wearing stability of the Bluetooth headset, and the ear hook made of elastic silicone can be comfortably hung on the ear, and there is no need to worry about the falling off of the Bluetooth headset.
