The invention relates to headphones which can facilitate the transfer of electrical power from the headphones' internal power source to other devices. A pair of headphones can connect to a device through a modified cable. The modified cable triggers the transfer of electrical power to the device. A pair headphones may have a modified port which, when connected to the device through a non-modified or regular cable, causes the transfer of power from the headphones. A power management component connected to the internal power source of the headphones helps control or regulate the transfer of power transfer to and from the headphones.
