A method of conserving battery power includes providing an electrical conductor that is connectable between an audio source and an accessory of the audio source. The conductor is capable of conducting a first electrical signal, containing audio information from the audio source, to the accessory. A second electrical signal is applied to the conductor when the first electrical signal is not present on the conductor. An aspect of the second electrical signal is measured while it is being applied to the conductor. An amount of battery power supplied to the accessory is reduced when the measured aspect meets a predetermined condition.
