Abstract
A method of preventing loss of headphones configured to communicate with a cell phone enables an alarm setting using an app on the cell phone; the app responding by continuously measuring a received magnitude of a wireless signal transmitted between the cell phone and the headphones. If the measured received magnitude is lower than a predetermined threshold value for a first predetermined time, an audible alarm is activated at the headphones. The continuous measurement and the activation of the alarm dependent on the measured received magnitude occur automatically, independent of any user interaction with the app after the alarm setting enablement. Another method addresses a corresponding issue in a similar way to prevent loss of one earbud of a pair.
