Abstract

An earphone device and a method for operation saves power and time when a user is interrupted from listening to communications. The earphone device includes a cable of a predetermined length, an ear jack, an earphone, a light sensor, and a controller. The ear jack is installed at one end of the cable, and is preferably arranged into an ear jack hole provided in a terminal for providing sound or voice reproduction. The earphone is installed at the other end of the cable and includes a speaker, and preferably inserted into and/or on a user'"'"'s ear. The light sensor is positioned to periodically sense brightness. The controller determines whether or not the earphone is actually in use (or non-use) based on the brightness periodically sensed by the light sensor. The transmission of audio signals to the earphone is enabled/disabled according to the determination by the earphone.
