The audio jack that is commonly seen on stereo headphones, audio devices such as the iPod, and many cell phones is known as the TRS Connector. The TRS phono plug connector is an audio jack with either 2 or 3 rings. TRS is an acronym representing Tip + Ring + Sleeve. The 2 ring version is for mono audio and the three ring version is for stereo audio. There are also other variants such as a four ring version which is often designed for camcorders, the extra ring for the video signal.
