  "textContent": "Provided are a Bluetooth headset, a charging cabin and a charging system thereof. The Bluetooth headset includes: a headset charging interface circuit, a control circuit, a level shifting circuit and a chip module. The headset charging interface circuit includes a detecting terminal connected to a power supply voltage terminal of the Bluetooth headset through the control circuit. When the detecting terminal is connected to a detecting pin of the charging cabin, a voltage of the detecting terminal is shifted from a first voltage provided by the power supply voltage terminal to a second voltage provided by the detecting pin of the charging cabin to trigger the control circuit to output a first level signal to the level shifting circuit, and then the first level signal is shifted to a power-off signal through the level shifting circuit to trigger the chip module to power off the Bluetooth headset.",
