Headphones are transducers that receive an electrical signal originating from an electronic source (such as a radio, receiver or audio player) that by design allow speakers to be placed near the ears to generate audible sound waves. Headphones are normally detachable and interchangeable, meaning that they can be easily plugged in or unplugged from the equipment that requires them, and that the same headphones can be used by various audio systems. In the context of telecommunications, headphones refer to a type of apparatus that refers to a combination of headphones and microphone for two-way communication. For example, a mobile phone.
