Abstract: This application relates to a wireless headset system and a wireless headset. The wireless headset system includes the wireless headset and a case. The case includes a lower cover, an upper cover, and an accommodation compartment. A first magnet is disposed on the upper cover. The wireless headset includes a processor and a magnetic sensor coupled to the processor. 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. The processor determines a status of the wireless headset based on the received magnetic field vector. The status of the wireless headset includes at least a state in which the case is closed and the headset is placed in the case, a state in which the case is open and the headset is placed in the case, and an out-of-case state.

Abstract: A wearable device includes a first optical transmitter configured to transmit first optical signals. One or more first optical sensors are configured to detect the first optical signals. A second optical transmitter, in the form of a vertical-cavity surface-emitting laser, is configured to transmit laser light. One or more second optical sensors are configured to detect the laser light transmitted by the second optical transmitter. One or more processors, connected to the first optical transmitter, the first optical sensors, the second optical transmitter, and the second optical sensors, and are configured to determine a wearing status of the wearable device based on optical signals detected by the first optical sensors and the second optical sensors.
