You only need to hide this lightweight device next to the headset to make free calls without using communication devices (mobile phones, computers, etc.). A Bluetooth headset is a hands-free headset that uses Bluetooth technology to allow users to avoid the entanglement of annoying wires and make calls in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business people to improve efficiency.

[0003] Traditional Bluetooth headsets are integrated with power supply batteries. When the power supply batteries are out of power, the Bluetooth headsets must be charged together with the batteries, and thus cannot be used any further, resulting in inconvenience in use. Therefore, existing Bluetooth headsets also have split structures in which the batteries can be removed and replaced. When such Bluetooth headsets are used, they are connected to the Bluetooth body through a detachable cover. Since such Bluetooth headsets can be removed, waterproofing is also an issue that needs to be considered. Existing waterproof structures generally include a sealing ring with a flat surface installed on the cover.
