This format is common on newer smartphones, mobile devices, and gaming consoles.Īlthough CTIA is a standard for newer phones, Apple uses a proprietary format implementation of CTIA to ensure that Apple accessories work seamlessly with Apple devices. The second ring then acts as the ground, while the sleeve handles the mic signal. The difference between CTIA and OMTP TRRS plugs.įor instance, the CTIA format transmits left and right audio channels through the tip and first ring. However, its position in the line-up varies depending on whether it follows the Cellular Telecommunications and Internet Association (CTIA) or Open Mobile Terminal Platform (OMTP) standards.Īs such, this connection configuration is also called the CTIA or OMTP TRRS jack connector format. 4-conductor plug (TRRS) TRRS Plug Diagram.Īvailable Connectors: Tip, sleeve, and two ring connectors with three insulating bands.Īside from transmitting stereo audio signals, the TRRS plug also has a dedicated conductor for a microphone. For that, see the TRRRS connector below.Ĭommon Usage: These are the most common jack connectors you’ll often see them on the end of most stock headphone cables. TRS cannot carry a balanced stereo signal as this requires at least four conductors. 3-conductor plug (TRS) TRS Plug Diagram.Īvailable Connectors: Tip, sleeve, and one ring connector with two insulating bandsĪdding a ring conductor (R) opens up different possibilities, such as support for balanced mono signals and unbalanced stereo signals. The longer the cable, the higher chance it’ll pick up more noise.Ĭommon Usage: You can find TS connectors mainly with guitars, instruments, and applications that do not require a long cable connection. However, since the ground is a reference point for the signal, it can pick up interference noises like an antenna. The tip connector carries the audio signal, while the sleeve acts as a return path and ground. To help with this, we’ll break down each format and explain its uses:Īvailable Connectors: Tip, sleeve, and one insulating bandĪ TS configuration is relatively straightforward. That said, it’s a good idea to familiarize yourself with plug conductor configurations to avoid functional errors in your audio devices. However, manufacturers can choose to configure jacks and plugs in various ways.īut one thing remains constant regardless of the configuration: both must be complementary.
