Wireless headset system and wireless headset

A wireless headset system, comprising:

• a wireless headset, comprising a processor and a magnetic sensor coupled to the processor, wherein the magnetic sensor is configured to detect a magnetic field vector around the wireless headset, and transmit the detected magnetic field vector to the processor, and wherein the magnetic sensor is a three-axis Hall effect sensor;
• and
• a case comprising a first cover, a second cover, and an accommodation compartment, wherein the accommodation compartment is configured to accommodate the wireless headset, a first magnet is disposed on the first cover, a second magnet is disposed on the second cover, and the first magnet and the second magnet are on opposite sides of the wireless headset and the magnetic sensor is between the first magnet and the second magnet when the wireless headset is accommodated in the accommodation compartment;
• and
• wherein the processor is configured to:
• determine the case is closed and the headset is placed in the case when the received magnetic field vector satisfies a first vector threshold;
• determine that the case is open and the headset is placed in the case when the received magnetic field vector satisfies a second vector threshold;
• and
• determine that the wireless headset is in an out-of-case state when the received magnetic field vector satisfies a third vector threshold.
