Headphones are a pair of small loudspeakers that are designed to be held in place close to a user's ears. They are also known as earspeakers, earphones or colloquially, cans. The alternate in-ear versions are known as or earbuds but also can be referred to as earphones. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones either have wires for connection to a signal source such as an autio amplifier, radio, cd player, portable media player, mobile phone, electronic musical instrument, or have a wireless receiver, which is used to pick up signal without using a cable.
