According to the solar portable TWS Bluetooth headset device 100 provided by the embodiment of the invention, the left Bluetooth headset, the right Bluetooth headset and the necklace type connecting piece 8 are arranged, the headset body 4 of the left Bluetooth headset and the right Bluetooth headset is arranged into two sections which can be rotatably connected and magnetically connected and fixed with the connecting block 82 of the necklace type connecting piece 8, so that when a user does not use the headset, the left Bluetooth headset and the right Bluetooth headset can be sucked and fixed on the necklace type connecting piece 8 worn on the neck of a human body, hung in front of a chest for storage, and no headset box is needed for storage; when the earphone is needed to be used, the left Bluetooth earphone and the right Bluetooth earphone are directly applied to be separated from the necklace type connecting piece 8 in front of the chest, and then the earphone is put into the ear, so that the earphone is convenient to store and take, and the whole earphone cannot independently occupy the storage space in a pocket or a bag of a user, so that the earphone is very convenient to carry. Meanwhile, the solar panel 9 is arranged on the surface of the earphone body 4 of the left and right Bluetooth earphone, so that the Bluetooth earphone can be directly charged by utilizing solar energy without carrying an earphone box, and the problem of battery endurance caused by insufficient electric quantity of the Bluetooth earphone is not required to be worried about when the Bluetooth earphone is used outdoors.

The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims, rather, as the description of the invention covers all embodiments of the invention.
