Stereo plug with additional function (four-pole)
The stereo plug with additional function is a variant of the stereo plug in which an additional ring has been separated from the sleeve, providing a total of four contacts. Stereo plugs with additional functions are mainly used on mobile phones and smartphones to connect headsets. Two different pin assignment variants are commonly used to transmit stereo audio and a mono microphone channel. Both variants use the tip to transmit the left audio channel and the first ring to transmit the right audio channel. In the Open Mobile Terminal Platform (OMTP) variant, the microphone channel is transmitted on the second ring and ground is on the third ring or socket. In the variant of the Cellular Telecommunications Industry Association (CTIA), also known as the inverted variant, the assignment of the microphone channel and the ground is swapped so that the ground is on the second ring and the microphone channel is on the socket.
Both variants allow the problem-free use of normal headphones with a three-pin jack plug in a four-pin socket, as the pin assignment of the tip and the first ring matches that of the three-pin plug. The microphone channel is then short-circuited through the plug directly to earth. The variant makes a difference when connecting a headset to a three-pin socket with a dedicated contact spring for earth (but without a contact ring for the shaft), such as those used in MP3 players or computers. If a four-pin plug is plugged into such a three-pin socket, the contact for earth is on the second ring. In the OMTP variant, the microphone channel is located here, meaning that a headset with a pin assignment according to the OMTP variant cannot be used in a three-pin socket. A headset with the CTIA pin assignment, on the other hand, can be used in three-pin sockets without any problems, as the earth is located on the second ring and is correctly contacted by the socket. In this case, the microphone channel is without contact and inevitably without function.
The pin assignment according to the OMTP variant is used by older mobile phones from Nokia, Samsung and Sony Ericsson. The CTIA variant, on the other hand, is used by Apple (iPhone, iPad, iPod and MacBook), AVM, Blackberry, Xbox One Stereo Headset Adapter, HTC, as well as newer Nokia, Samsung and Sony mobile phones. It is also used in some notebooks from HP, Lenovo and Dell, as well as in other devices. On some mobile phones, especially older ones, the pin assignment may differ from the variants described above. Standard accessories may then only be able to be used with adapters.
