1. A system comprising:
- a mobile device comprising a transmission module for transmitting at least one of data or voice signals over a microwave frequency band; and
a wireless headset comprising a transceiver that enables the wireless headset to wirelessly communicate with the mobile device during a time when the mobile device and wireless headset are linked within a personal area network (PAN);
wherein the wireless headset is configured to receive instructions from the mobile device to enter a sleep mode;
wherein the transceiver is turned off during the sleep mode;
wherein the wireless headset further comprises a microphone configured to receive audio during the sleep mode;
wherein the wireless headset further comprises match detecting circuitry configured to determine whether the received audio matches a predetermined audio file; and
wherein the predetermined audio file includes audio signals of a ringtone of the mobile device.
